Abstract
There has been an increase in the diagnosis of thyroid nodules in recent years. In addition to the well-known criteria, features that are likely to increase the risk of malignancy are in the research process. In this study, we aimed to evaluate the malignant potential of nodules that expand the thyroid capsule ultrasonographically. A total of 109 patients with thyroid capsule-expanding nodules and 288 patients with non-expanding nodules were included in the study. Demographical data, ultrasonography features, and cytology results were noted, and histopathological findings were determined in operated patients. While malignant cytology was detected in 5.5% of capsule-expanding nodules in FNAB results, this rate was 0.7% in the non-capsule expanding group (p<0.001). According to the histopathological results, the incidence of malignancy was 15.6% in the capsule-expanding nodule group, while it was 3.1% in the other group (p=0.001). As a result of logistic regression analysis, it was determined that the risk of malignancy increased by 4.44-fold (95% CI 1.4-13.8, p=0.01) in patients with capsule-expanding nodules. Other features that increased the risk of malignancy were hypoechogenicity, microcalcification, and irregular margin presence. In this study, we found that the risk of malignancy increased in nodules expanding the thyroid capsule. Based on the increasing study data on this subject, monitoring thyroid capsule expansion in nodules may take its place among the criteria for malignancy in future evaluations.

Comparison of Cytological Adequacy between 23- and 25-Gauge in Ultrasound-Guided Fine-Needle Aspiration of Thyroid Nodules: A Single-Center Prospective Study. Acta Cytol 2024; 68:121-127. [PMID: 38599193 DOI: 10.1159/000538290] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2023] [Accepted: 03/08/2024] [Indexed: 04/12/2024]
Abstract
INTRODUCTION Approximately 15% of fine-needle aspiration (FNA) of thyroid nodules are considered nondiagnostic. Several factors are potentially involved, including clinical and nodule features but also the gauge (G) of the needle used. However, few studies have compared the cytological adequacy obtained with different gauge needles and the data are controversial. We aimed to evaluate cytological adequacy results using 23- or 25-G needles. METHODS This study is an observational and prospective study of thyroid nodules submitted to ultrasound-guided FNA. The procedure was performed randomly using 23- or 25-G needles. The samples were reported by different cytopathologists who were blinded to the information of the gauge of the needle used. Statistical analysis was performed to compare cytological adequacy of FNA between the two groups. RESULTS A total of 177 thyroid nodules were included - 98 (55.4%) using 23-G and 79 (44.6%) using 25-G needles. The 23-G group presented a higher rate of cytological adequacy (69.4% [68/98] vs. 46.8% [37/79], p = 0.002). No differences were found between the two groups regarding patient or nodule characteristics. On logistic regression, 23-G needles correlated with better cytological adequacy (unadjusted OR 2.57 [95% CI: 1.39-4.77]), even after adjusting for nodule dimension, location, and type of cytology (slides +/- additional liquid-based cytology) (adjusted OR 2.44 [95% CI: 1.23-4.84]). CONCLUSION The gauge of the needle used was found to be an independent predictor of cytological adequacy, with 23-G needles providing more adequate samples. Further investigation is needed to confirm our results in order to stablish the optimal diagnosis technique.

Abstract
Thyroid nodules are common findings, particularly in iodine-deficient regions. Our paper aims to revise different diagnostic tools available in clinical thyroidology and propose their rational integration. We will elaborate on the pros and cons of thyroid ultrasound (US) and its scoring systems, thyroid scintigraphy, fine-needle aspiration cytology (FNAC), molecular imaging, and artificial intelligence (AI). Ultrasonographic scoring systems can help differentiate between benign and malignant nodules. Depending on the constellation or number of suspicious ultrasound features, a FNAC is recommended. However, hyperfunctioning thyroid nodules are presumed to exclude malignancy with a very high negative predictive value (NPV). Particularly in regions where iodine supply is low, most hyperfunctioning thyroid nodules are seen in patients with normal thyroid-stimulating hormone (TSH) levels. Thyroid scintigraphy is essential for the detection of these nodules. Among non-toxic thyroid nodules, a careful application of US risk stratification systems is pivotal to exclude inappropriate FNAC and guide the procedure on suspicious ones. However, almost one-third of cytology examinations are rendered as indeterminate, requiring "diagnostic surgery" to provide a definitive diagnosis. 99mTc-methoxy-isobutyl-isonitrile ([99mTc]Tc-MIBI) and [18F]fluoro-deoxy-glucose ([18F]FDG) molecular imaging can spare those patients from unnecessary surgeries. The clinical value of AI in the evaluation of thyroid nodules needs to be determined.

Abstract
PURPOSE To identify commonly used needle types in cross-sectional interventional radiology (CSIR) and to review features and safety profiles of those needles. METHODS Members of the Society of Abdominal Radiology (SAR) emerging technologies commission (ETC) on CSIR were sent a 13-question survey about what needles they use for common CSIR procedures: random and targeted solid organ biopsy, ultrasound-guided paracentesis, and ultrasound-guided thyroid fine needle aspiration (FNA). Results were compiled with descriptive statistics, and features of the most commonly used needles were reviewed. RESULTS 19 surveys were completed (response rate 57.6%, 19/33) from 16 institutions. For solid organ biopsies, the majority of respondents reported using an 18-gauge needle with an automatic firing mechanism and a variable throw length option. The most commonly used needle for both random and targeted biopsies was the Argon BioPince (26.3%, 5/19) The three most commonly used needles for solid organ biopsies all featured automatic firing, variable throw length options, and 18-gauge size. A 5 French Cook Yueh needle was most the most commonly used paracentesis needle (36.8%, 7/19). For thyroid FNA, all respondents used spinal needles, and 25-gauge was the most common size (72.2%, 13/18). CONCLUSION Abdominal radiologists use a variety of needles when performing common interventional procedures. Members of the SAR CSIR ETC commonly use automatic, 18-gauge, variable throw length needles for solid organ biopsies, 5 French catheter style needles for paracentesis, and 25-gauge spinal needles for thyroid FNA.

Abstract
PURPOSE Thyroid Bethesda classification system provides 6 diagnostic categories, the first being a sample deemed non-diagnostic or insufficient and requiring a subsequent second biopsy. Our objective was to evaluate differences in non-diagnostic fine needle aspiration (FNA) of thyroid nodules conducted with a 23-gauge(G) needle vs. those conducted with a 25 G needle. METHODS Data from 298 aspiration procedures using either 23 G or 25 G needles were collected, including cytological findings, ultrasound characteristics and patient demographics. The samples were classified as diagnostic or non-diagnostic according to final cytology. RESULTS There was no statistically significant difference between the 25 G and 23 G needles in terms of non-diagnostic rates (35.7%, 31.9%; p = 0.494). Nodules defined as cystic had higher non-diagnostic rates (p < 0.05). Older patients as well as cystic nodules were associated with a higher non-diagnostic rate (OR = 1.018, p = 0.047, OR = 13.533, p = 0.0001, respectively), while nodule size was associated with lower non-diagnostic rates (OR = 0.747, p = 0.017). CONCLUSIONS The use of 25 G needle did not produce a lower non-diagnostic rate when compared to 23 G needle. Larger nodules might increase diagnostic rates, while older patients and cystic nodules are prone to inadequate samples. Patients and caregivers should be aware that FNA of small or cystic nodules as well as nodules in older patients may result in a higher non-diagnostic rate. Further research comparing other needles gauges should be conducted.

Abstract
PURPOSE This study was aimed to compare thyroid fine needle aspiration biopsy (FNAB) techniques (conventional vs. whirling) in terms of cell harvesting ability ex vivo, the unsatisfactory rate and complication rate in vivo, and multi-operator performance in a phantom study. METHODS In the ex vivo study, cell counts per background at ×100 magnification were compared between both techniques. In the in vivo study, 70 patients who underwent whirling FNAB from July 2019 to November 2019 were retrospectively compared to 140 matched patients who underwent conventional FNAB from January 2018 to November 2019 regarding the unsatisfactory rate and complication rate. As a subgroup analysis, thyroid nodules in difficult biopsy situations (nodule diameter <10 mm and location within 3 mm from major anatomical structures) were compared. In the phantom study, eight operators with varying experience recorded levels of dexterity and needle tip visualization, and their preferences for both techniques. RESULTS In the ex vivo study, cell counts were comparable between both techniques in all thyroid nodule mimickers (80.0% vs. 87.5%, P=0.178). In the in vivo study, the unsatisfactory rate was comparable between the two groups (15.7% vs. 12.9%, P=0.859). In the subgroup analysis, the whirling technique demonstrated a lower unsatisfactory rate (5.9% vs. 24.2%, P=0.045) and a lower complication rate (0% vs. 6.1%, P=0.553). In the phantom study, the whirling technique demonstrated better dexterity and needle tip visualization and was preferred by all operators. CONCLUSION This newly proposed whirling technique for thyroid FNAB may be effective and safe, especially in difficult biopsy situations.

Abstract
Background Classifying thyroid lesions is challenging; nonetheless, using ultrasonography may allow for accurate diagnosis, differentiation and management of thyroid lesions and help avoid unnecessary biopsy. Objectives The main objective of the study is to determine the diagnostic accuracy of ultrasonography in classifying thyroid nodules compared with fine-needle aspiration. Materials and Methods This retrospective study included all 68 patients diagnosed with thyroid nodules at King Fahd Hospital of the University, Al Khobar, Saudi Arabia, between June 1, 2014, and November 30, 2016. Parameters were selected based on the Society of Radiologists in Ultrasound criteria. Ultrasonographic features, namely, nodule margins, echotexture, vascularity and calcifications, and fine-needle aspiration cytology (FNAC) results were reviewed by two radiologists blinded to each other's findings and validated by another experienced interventional radiologist. Ultrasonography results were compared against that of FNAC to calculate sensitivity and positive- and negative-likelihood ratios, and the nodule types were compared using Fisher's exact test. Results Of the 68 nodules analyzed, 59 were reported as benign using FNAC (specificity = 95%; P < 0.001). Of these 59, 56 were also reported as benign using ultrasonography. The specificity of ultrasonography in determining benign nodules was 94.9%, and the positive- and negative-likelihood ratios were 13.0 and 0.35, respectively. Six of the nine suspicious nodules were confirmed as malignant using FNAC, and the ultrasonography and FNAC findings were strongly associated (P = 0.001). According to the Society of Radiologists in Ultrasound criteria, FNAC and ultrasonography findings were significantly associated for nodule calcification (P = 0.001) and echogenicity (P = 0.001). Conclusion The diagnostic specificity of ultrasonography and FNAC in this study are consistent with those reported previously, indicating that ultrasonography reliably classifies thyroid nodules, and thus can assist in the decision-making regarding need for biopsy.

Abstract
AIMS Today, the color Doppler ultrasonography is used to further evaluate suspected malignant tumors. This study investigates the malignant thyroid nodules using color Doppler. METHODS After extracting true positive, false positive, false negative, and true negative among included studies, a quality was evaluated by the Quality Assessment of Diagnostic Accuracy Studies-2 tool. Sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, and diagnostic odds ratio (with 95% confidence interval) were found using a random effect model. Summary receiver operating characteristic curves (SROC) were used to assess relationship between sensitivity and specificity. The area under the curve of the SROC was calculated to estimate the performance of color Doppler ultrasound to distinguish malignant thyroid nodules. Our registration code in PROSPERO is CRD42018111198. RESULTS Of 1125 articles, 288 articles were selected for the further investigation. After excluding irrelevant and poor articles, 20 studies were included for the meta-analysis. According to a random effect model, the pooled sensitivity and specificity of color Doppler ultrasound to distinguish malignant thyroid nodules were estimated as 0.74 (95% CI 0.62-0.83; [Formula: see text]) and 0.70 (95% CI 0.56-0.81; [Formula: see text]), respectively. The SROC curve consists of representing the paired results for sensitivity and specificity. According to SROC, AUC = 0.78 (95% CI 0.74-0.81) is between 0.75 and 0.92, so that color Doppler ultrasound has a good accuracy. CONCLUSION Color Doppler is a valuable non-invasive method for evaluating thyroid nodules, and it is a high-sensitivity diagnostic tool for assessing thyroid nodules. Resistive index > 0.75 and a pattern III or more in color Doppler predicts malignant with the confidence. Due to its precision, cost-efficiency, easy access, and non-invasive nature, color Doppler should be included in the standard clinical protocol for the decision-making period and the treatment evaluation.

Abstract
Concerning the needle size for thyroid fine needle aspiration cytology (FNAC), 25-27-gauge needles are generally used in Western countries. However, in Japan, the use of larger needles (21-22-gauge needles) is common. The aim of our study was to determine the optimal needle size for thyroid FNAC. We performed ultrasound-guided FNAC for 200 thyroid nodules in 200 patients using two different-sized needles (22 and 25 gauge). For each nodule, two passes with the different-sized needles were performed. The order of needle sizes was reversed for the second group of 100 nodules. The second aspiration was more painful than the first, regardless of the needle size. An association with more severe blood contamination was more frequently observed with the use of 22-gauge needles (32.0%) than with the use of 25-gauge needles (17.5%) and in the second aspiration (37.5%) than in the initial aspiration (12.0%). The initial aspiration samples were more cellular than the second aspiration samples. Regarding the unsatisfactory and malignancy detection rates, there was no statistical difference between the needles. In three of seven markedly calcified nodules, it was difficult to insert 25-gauge needles into the nodules. In terms of the diagnostic accuracy and pain, either needle size can be used. We recommend using 22-gauge needles for markedly calcified nodules because 25-gauge needles bend more easily in such cases. We demonstrated that the initial aspiration tended to obtain more cellular samples and to be less contaminated. Thus, the initial aspiration is more important and should be closely attended.

Abstract
Purpose This study aimed to clarify the sonographic features of suture granuloma and recurrent carcinoma newly detected after thyroidectomy. Materials and Methods We retrospectively analyzed ultrasound reports with images of 25 cases of suture granuloma and 18 cases of recurrent carcinoma that newly appeared in the resected area after thyroidectomy in our institution. Results Both suture granulomas and recurrent carcinomas more frequently exhibited multiple lesions rather than solitary lesions. Suture granulomas tended to appear in the more superficial areas than the carotid artery, while recurrent carcinomas were more common between the trachea and carotid artery. A total of 10 of the 11 suture granulomas that we followed up decreased in size. Recurrent carcinomas showed irregular shape (55.6%), taller-than-wide shape (38.9%), low internal echogenicity (83.3%), and no punctate microcalcifications. By contrast, suture granulomas were fusiform in shape (56.0%) and showed linear internal echo parallel to the tissue plane on the longitudinal scan (64.0%). The vascular flow sign was mild to none in the majority of both lesions. Conclusion Fusiform shape and linear internal echoes indicate suture granuloma, while irregular shape, taller-than-wide shape, and low echogenicity indicate recurrent carcinoma. Given that the clinical management of suture granuloma differs from that of recurrent carcinoma, it is important to distinguish between these two lesions.

Abstract
Papillary thyroid carcinoma (PTC) arising within a follicular adenoma is an exceptionally rare histopathological subtype that shows the nuclear features of PTC within a benign-appearing, circumscribed follicular adenoma. Although it is clinically significant because of its malignant nature, its ultrasonographic features have not been described previously. A 26-year-old man presented with a heterogeneous isoechoic solid nodule with a marked hypoechoic solid focus and a low echoic peripheral rim in the right thyroid gland on ultrasonography. On color Doppler images, markedly increased vascularity was seen in the hypoechoic solid component. An ultrasound-guided gun biopsy suggested a follicular neoplasm. In the evaluation of a hemithyroidectomy specimen, thyroid follicles and a thin fibrous capsule were seen, which favored a follicular adenoma with tumor cells in a focal area indicating papillary carcinoma. Here, we report a case of PTC arising within a follicular adenoma and discuss possible considerations in thyroid ultrasonographic examinations.

Abstract
PURPOSE We aimed to determine the contribution of vacuum-assisted modified Menghini type needle to diagnosis of ultrasound-guided fine needle aspiration biopsy (FNAB) of the thyroid evaluated by a pathologist at the bedside. METHODS A total of 147 thyroid nodules in 138 patients (122 women, 16 men) were included in this prospective study. Sonographic features of nodules, number of aspirations, pain and pain severity during the process, hemorrhage, and presence of sample obtained for cell block analysis were recorded and analyzed with the results of aspiration biopsy. RESULTS Using the 21G modified Menghini type needle, a diagnosis could not be reached in 14.3% of nodules. Adequate samples for cell block analysis were obtained in 47 nodules (32%), 17 of which contributed to the diagnosis. While the difference between diagnostic cytopathology results and the contribution of the cell block were statistically significant, obtainability of cell block samples was not significantly correlated with the number of aspirations or the presence of a cystic component in the nodule. CONCLUSION FNAB with 21G vacuum-assisted modified Menghini type needle is a safe procedure with very low complication rates. In addition to the cytologic smear samples, microtissue fragments obtained with this method help pathologists in the diagnosis of thyroid nodules.

Abstract
The aim of the present study was to verify the optimal method to obtain enough fine-needle aspiration (FNA) materials for detecting thyroid malignancy. A prospective study was performed by comparing two different regional standards of care. In one group a traditional FNA method mainly used in Asian countries, including China, was performed in which a single pass of a 22-G needle was applied with or without aspiration. In the other group, the method mainly used in Western countries was performed in which three passes of a 25-G needle with non-aspiration were undertaken for thyroid nodules. The study included 718 thyroid nodules from 695 patients. These nodules were allocated for three different methods of performing thyroid FNA. There were 332 thyroid nodules subjected to the traditional Asian FNA method using a 22-G needle with aspiration for 142 nodules and non-aspiration for 190 nodules. FNA using the Western method was performed with three passes of non-aspiration using 25 G for 386 nodules. All the FNAs were performed with the guidance of ultrasound. The components of the nodules were documented. All the samples were reported using the Bethesda System for Reporting Thyroid Cytopathology. Among the 22 G group, the non-diagnostic rate in the aspiration group was as high as 76.76%, which was significantly higher than 44.21% in the non-aspiration group (P<0.01). For the non-aspiration group, the non-diagnostic rate in the 25 G group was 34.97%, which was significantly lower than 44.21% in the 22 G group. In general, the non-diagnostic rate for the 25-G needle was 34.97%, which was significantly lower than 58.13% in all the 22 G groups. For the solid and mixed nodules, the non-diagnostic rate was lower in the 25-G needle group compared to the 22 G groups with statistical significance. The non-aspiration method using a 25-G needle with multiple passes can result in a higher diagnostic rate for thyroid FNA.

Abstract
The objective of this study was to investigate the effect of the ultrasonographic (US) characteristics and ultrasound elastography (UE) patterns on the probability of a nondiagnostic result when performing ultrasound-guided fine-needle aspiration (UG-FNA) cytological sampling of solid thyroid nodules larger than 10 mm, to determine the efficacy of needle tip localization in UG-FNA. We retrospectively reviewed the cytological results of 710 samples from 355 patients. We compared the US characteristics and UE patterns between nodules with nondiagnostic and diagnostic results, using univariate and multivariate analyses. Among the 710 samples, 81 samples (11.4 %) from 41 patients had nondiagnostic results. According to multivariate analysis, the combinations of hypoechogenicity with avascularity [odds ratio (OR) = 2.42; 95 % confidence interval (CI) 1.37-3.72; p < 0.05], hypoechogenicity with the "hard pattern" (OR = 2.12; 95 % CI 1.58-4.59; p < 0.05), and hypoechogenicity with avascularity and the hard pattern (OR = 2.61; 95 % CI 1.40-5.21; p < 0.05) were risk factors that increased the incidence of nondiagnostic results in UG-FNA. UG-FNA was more likely to yield nondiagnostic results when the needle tip sampling region displayed hypoechogenicity and avascularity in US and the hard pattern in UE.

Abstract
OBJECTIVE We evaluated the diagnostic role of ultrasonography-guided core needle biopsy (CNB) according to ultrasonography features of thyroid nodules that had inconclusive ultrasonography-guided fine-needle aspiration (FNA) results. METHODS A total of 88 thyroid nodules in 88 patients who underwent ultrasonography-guided CNB because of previous inconclusive FNA results were evaluated. The patients were classified into three groups based on ultrasonography findings: Group A, which was suspicious for papillary thyroid carcinoma (PTC); Group B, which was suspicious for follicular (Hurthle cell) neoplasm; and Group C, which was suspicious for lymphoma. The final diagnoses of the thyroid nodules were determined by surgical confirmation or follow-up after ultrasonography-guided CNB. RESULTS Of the 88 nodules, the malignant rate was 49.1% in Group A, 12.0% in Group B and 90.0% in Group C. The rates of conclusive ultrasonography-guided CNB results after previous incomplete ultrasonography-guided FNA results were 96.2% in Group A, 64.0% in Group B and 90.0% in Group C (p=0.001). 12 cases with inconclusive ultrasonography-guided CNB results were finally diagnosed as 8 benign lesions, 3 PTCs and 1 lymphoma. The number of previous ultrasonography-guided FNA biopsies was not significantly different between the conclusive and the inconclusive result groups of ultrasonography-guided CNB (p=0.205). CONCLUSION Ultrasonography-guided CNB has benefit for the diagnosis of thyroid nodules with inconclusive ultrasonography-guided FNA results. However, it is still not helpful for the differential diagnosis in 36% of nodules that are suspicious for follicular neoplasm seen on ultrasonography. ADVANCES IN KNOWLEDGE This study shows the diagnostic contribution of ultrasonography-guided CNB as an alternative to repeat ultrasonography-guided FNA or surgery.

Abstract
OBJECTIVES To compare the diagnostic performance of radiologists and to determine interobserver and intraobserver variability with regard to differentiation of benign and malignant thyroid nodules using prospectively obtained 2-dimensional (2D) and 3-dimensional (3D) sonograms. METHODS This study had Institutional Review Board approval, and the requirement for patient informed consent was waived. Conventional 2D and 3D sonograms were obtained from 82 patients (age range, 20-77 years; mean age, 51 years) with 91 thyroid nodules (15 cancers, 13 indeterminate, and 63 benign lesions) before diagnostic fine-needle aspiration. Three radiologists reviewed stored 2D and 3D images for internal content, shape, margin, echogenicity, echo texture, and the presence of calcification and estimated the level of suspicion as to the probability of malignancy according to known sonographic criteria. The diagnostic performance of 2D images was compared with that of 3D images. RESULTS For all readers, interpretation using 3D images was more sensitive and specific than that using 2D images for diagnosis of malignant thyroid nodules, with the exception of specificity for reader 1. However, differences were not statistically significant (P > .05). Area under the receiver operating characteristic curve values were 0.83 for 2D images and 0.92 for 3D images for reader 1; 0.78 for 2D images and 0.89 for 3D images for reader 2; and 0.89 for 2D images and 0.93 for 3D images for reader 3. Interobserver agreement between the 3 radiologists for differentiation of benign and malignant thyroid nodules was better for 3D images (κ = 0.49) than for 2D images (κ = 0.15). Intraobserver variability for nodule descriptions and assessments using 3D and 2D images was fair to moderate. CONCLUSION The performance of radiologists and interobserver and intraobserver agreement for characterization of thyroid nodules were better when 3D sonograms were used than when 2D sonograms were used.

Abstract
OBJECTIVES To evaluate the efficacy and safety of MRI-guided percutaneous biopsy procedures of head and neck lesions using 0.23T open MRI with optical tracking. METHODS A retrospective analysis of 77 patients (51 male, 26 female; mean age, 43 years; range, 11-88 years) who underwent MRI-guided percutaneous biopsy of a head and neck lesion was performed. Mean lesion diameter was 3 cm (range, 1-7.8 cm). Rapid gradient echo sequences were used for image guidance. 23/77 lesions were biopsied after intravenous gadolinium. Tissue sampling techniques included needle aspiration (n = 19) and core needle biopsy (n = 58). Outcome variables included technical success, diagnostic accuracy, procedure time and complications. RESULTS In all patients, a sufficient amount of tissue for pathological analysis was obtained. Pathological analysis diagnosed 41 malignant lesions and 36 benign lesions. In 42 cases, surgical correlation was available. In 35 cases, the final diagnosis was confirmed by imaging and clinical follow-up. MR-guided biopsy had a sensitivity, specificity, positive predictive value, negative predictive value and accuracy of 93.2%, 100%, 100%, 91.7%, and 96%, respectively. Procedure time was 29 min (range, 15-47 min). No major complications occurred. CONCLUSIONS MRI-guided biopsy of head and neck lesions has a high diagnostic performance and is safe in clinical practice. KEY POINTS • MRI-guided biopsy helps clinicians to assess patients with head&neck masses. • Differention of malignant and benign lesions is possible with 96% accuracy. • The safety profile of MRI-guided biopsy of head&neck lesions is favorable. • MRI guidance enables accurate biopsy without the use of ionizing radiation.

Abstract
PURPOSE The purpose of the present study was to integrate safety-engineered devices into outpatient fine-needle aspiration (FNA) biopsy of the thyroid in an interventional radiology practice. MATERIALS AND METHODS The practice center is a tertiary referral center for image-directed FNA thyroid biopsies in difficult patients referred by the primary care physician, endocrinologist, or otolaryngologist. As a departmental quality of care and safety improvement program, we instituted integration of safety devices into our thyroid biopsy procedures and determined the effect on outcome (procedural pain, diagnostic biopsies, inadequate samples, complications, needlesticks to operator, and physician satisfaction) before institution of safety devices (54 patients) and after institution of safety device implementation (56 patients). Safety devices included a patient safety technology-the mechanical aspirating syringe (reciprocating procedure device), and a health care worker safety technology (antineedlestick safety needle). RESULTS FNA of thyroid could be readily performed with the safety devices. Safety-engineered devices resulted in a 49% reduction in procedural pain scores (P < 0.0001), a 56% reduction in significant pain (P < 0.002), a 21% increase in operator satisfaction (P < 0.0001), and a 5% increase in diagnostic specimens (P = 0.5). No needlesticks to health care workers or patient injuries occurred during the study. CONCLUSIONS Safety-engineered devices to improve both patient and health care worker safety can be successfully integrated into diagnostic FNA of the thyroid while maintaining outcomes and improving safety.

Abstract
Fine-needle aspiration (FNA) biopsy of thyroid nodules is minimally invasive and safe and is usually performed on an outpatient basis. However, the optimal application of FNA requires not only technical skill but also an awareness of the limitations of the procedure, the indications for its use, the factors that affect the adequacy of the biopsy specimen, and the postprocedural management strategy. Ultrasonographic (US) features that are considered indications for FNA include single and multiple thyroid nodules. The results of FNA biopsy are operator dependent. In addition, the results may be affected by the lesion characteristics, the accuracy of lesion and needle localization, the method of guidance, the number of aspirated samples, the needle gauge, the aspiration technique, and the presence or absence of on-site facilities for immediate cytologic examination. With regard to postprocedural management, nodules that are diagnosed as benign on the basis of an adequate FNA specimen should be monitored with follow-up US. Circumstances that necessitate repeat FNA include sample inadequacy, nodule enlargement, cyst recurrence, or clinical or imaging findings that arouse suspicion about the presence of a malignancy even when cytologic findings in the biopsy specimen indicate benignity.

Abstract
BACKGROUND The primary goal of ultrasonography (US) in the evaluation of a thyroid nodule is to determine its malignancy, although the diagnosis of a malignant nodule on the basis of US alone is nearly impossible. The aim of this prospective study was to evaluate the predictive value of sonographic features in the preoperative diagnosis of malignant thyroid nodules, and to determine the important features of sonography. METHODS This prospective study included 550 consecutive patients with , thyroid nodules. Nodules were divided into two groups on the basis of pathological diagnosis: group 1 consisted of 1,633 nodules with a benign pathology, and group 2 consisted of 293 nodules with a malignant pathology. RESULTS Microcalcifications, blurred nodular margins, and solid and hypoechoic appearance were more common in malignant nodules compared to benign nodules (89.1% versus 5%; 64.5% versus 4.7%; 81.6% versus 30.6% ; and 62.5% versus 43.1%, respectively; p < 0.001). There was a positive correlation between the detection of malignant thyroid nodules and microcalcification (rs = 0.791, p = 0.0001), blurred nodular margin (rs = 0.625, p = 0.0001), solid appearance (rs = 0.376, p = 0.0001), and hypoechoic appearance (rs = 0.141, p = 0.0001). Microcalcifications, blurred nodular margins, and solid and hypoechoic appearance were independent determinants of malignancy upon US examination of thyroid nodules (OR: 159, OR: 37, OR: 9.9, and OR: 2.2, respectively). CONCLUSION Although we did not identify a single feature indicative of malignancy in the sonographic examination of nodules, microcalcification and blurred margin were the strongest correlates for malignancy.

Abstract
We review the different techniques in the diagnostic of thyroid nodule. The ultrasound and, especially, sonographically guided fine-needle aspiration (US-FNA), are the most accurate diagnostics tests to achieve a correct diagnosis of thyroid nodule, which is only done better by the surgery treatment and the pathology study of all lesion. We review the situations in which US-FNA is necessary and the different diagnostic and therapeutics options. Finally, we propose algorithms for the management of a solitary thyroid nodule, multinodular goiter and casually discovered nodule.

Abstract
AIM To evaluate the effects of sonographic characteristics of thyroid nodules, the diameter of needle used for sampling, and sampling technique on obtaining sufficient cytological material (SCM). MATERIALS AND METHODS We performed sonography-guided fine-needle biopsy (FNB) in 232 solid thyroid nodules. Size-, echogenicity, vascularity, and localization of all nodules were evaluated by Doppler sonography before the biopsy. Needles of size 20, 22, and 24 G were used for biopsy. The biopsy specimen was acquired using two different methods after localisation. In first method, the needle tip was advanced into the nodule in various positions using a to-and-fro motion whilst in the nodule, along with concurrent aspiration. In the second method, the needle was advanced vigorously using a to-and-fro motion within the nodule whilst being rotated on its axis (capillary-action technique). RESULTS The mean nodule size was 2.1+/-1.3 cm (range 0.4-7.2 cm). SCM was acquired from 154 (66.4%) nodules by sonography-guided FNB. In 78 (33.6%) nodules, SCM could not be collected. There was no significant difference between nodules with different echogenicity and vascularity for SCM. Regarding the needle size, the lowest rate of SCM was obtained using 20 G needles (56.6%) and the highest rate of adequate material was obtained using 24 G needles (82.5%; p=0.001). The SCM rate was 76.9% with the capillary-action technique versus 49.4% with the aspiration technique (p<0.001). CONCLUSION Selecting finer needles (24-25 G) for sonography-guided FNB of thyroid nodules and using the capillary-action technique decreased the rate of inadequate material in cytological examination.

Abstract
UNLABELLED The purpose of this study is to assess the specific ultrasonic characteristics of papillary thyroid carcinoma and to determine the relative frequency of various patterns of papillary carcinoma on gray-scale ultrasonography (US) and color Doppler ultrasonography (CDU). METHODS We retrospectively reviewed US features in 51 patients with confirmed papillary thyroid carcinoma. The features were analyzed based on tumor size, echogenicity, echotexture, boundary, margin, shape, and calcification pattern on gray-scale US imaging, and on patterns of vascularity on CDU. We obtained the relative frequency of features and classified these features into three categories: common (> or =50% of lesions), less common (>10% but <50%), and uncommon (< or =10%). Individual differences and combinations of features were also analyzed. RESULTS In total, 67 nodules were enrolled in our study. The sizes of 76% of nodular lesions were <20.0 mm. Common US features of papillary carcinoma included: a homogeneous hypoechoic solid picture; a poorly defined boundary; an irregular margin; the absence of halo; the absence of calcifications or microcalcifications; and mixed perinodular and intranodular blood flow patterns. Less common features included: a heterogeneous hypoechoic or very hypoechoic picture; microcalcifications; a well-defined boundary; a regular margin; a halo with uneven thickness or an incomplete halo; and a taller-than-wide shape. Uncommon features included: an isoechoic picture; solid with cystic components; coarse calcifications; mixed coarse calcifications and microcalcifications; "inferno"-type blood flow; and absence of blood flow. On average, each nodule had 4.9 US features considered common, 1.8 US features considered less common, and 0.4 US feature considered uncommon. Features such as predominantly cystic composition, hyperechoic texture, and hypoechoic halo with even thickness were never found in our study. The top two common manifestations of papillary carcinoma were solid architecture and mixed perinodular and intranodular blood flow signals. CONCLUSION All lesions in our series had a predominantly solid characteristic on gray-scale US.

Abstract
Although high resolution ultrasonography (US) is helpful in the differentiation of suture granulomas from recurrent thyroid cancer in most cases, a definite diagnosis cannot always be made. We report a case that mimicked recurrent thyroid cancer on US and 2-[fluorine-18] fluoro-2-deoxy-D-glucose (FDG) positron emission tomography (PET), but diagnosis of a suture granuloma was confirmed by a US-guided fine needle aspiration biopsy (FNAB). In order to avoid unnecessary operations, the differential diagnosis between postoperative suture granulomas and recurrent cancer is important.

Abstract
The goals of imaging in head and neck cancer are to establish tumor extent and size, to assess nodal disease, to evaluate for perineural tumor spread, and to distinguish recurrent tumor from post-treatment changes. MRI is the preferred modality for assessment of nasopharyngeal, sinonasal, and parotid tumors, because of better contrast resolution, high frequency of perineural spread, and less prominent motion artifacts. MRI is the best modality to delineate the extent of intraorbital and intracranial extension of malignant tumors. Tumors of the oropharynx, larynx, and hypopharynx are frequently primarily imaged with CT, which is less affected by breathing and swallowing artifacts. MRI is also the initial study of choice for tumors confined to the oral tongue, and possibly also for other oral cavity locations because MRI is superior in detection of tumor spread into the bone marrow. There is no clear advantage of CT or MRI for evaluation of nodal disease. Positron emission tomography (PET) is very sensitive for metastatic lymph nodes that are at least 8 mm in size and is the technique of choice in dubious cases. Imaging-guided biopsies are performed whenever needed. For imaging of treated head and neck cancer, PET scans have been found to generally offer higher sensitivity than MRI or CT. Combined PET/CT may be the modality of choice because it almost completely eliminates the false-positive and false-negative PET findings. Patients with head and neck cancer who are referred to tertiary care centers commonly arrive with cross-sectional images obtained at other institutions. Reinterpretation of these studies by dedicated radiologists frequently leads to changes in findings, which alter treatment and affect prognosis.

Abstract
Ultrasound (US)-guided biopsy of thyroid nodules, abdominal masses, liver masses, random core liver biopsies, as well as aspiration of abdominal or pleural fluid is now routine practice. The ability of US to guide biopsy of abnormalities seen on cross-sectional imaging studies is well recognized as an efficient and effective means of achieving a tissue diagnosis. Its use requires basic knowledge of US image analysis, but clinically useful intuitive and nonintuitive methods can enhance its strengths. The purpose of this review is to provide a practical guide to some of these tricks that may be useful in everyday clinical practice.

Abstract
Ultrasound plays a prominent role in the management of thyroid disease and parathyroid adenomas. It can detect clinically impalpable thyroid nodules and characterize them as cystic, solid, or complex. Determining that a nodule is definitively benign or malignant is difficult, and so when indicated an ultrasound-guided fine-needle aspiration can be performed. In the follow-up of patients with thyroid cancer, ultrasound can be used alone or in conjunction with computed tomography (CT)/magnetic resonance imaging (MRI) to detect recurrent disease. Recurrences can be confirmed using ultrasound to guide fine-needle aspirations. To locate parathyroid adenomas, ultrasound is often used in conjunction with sestamibi scanning. If both studies agree on the location of the adenoma, the surgeon can perform focused surgery for its removal. In patients in whom the studies do not agree or in whom they do not detect the adenoma, further evaluation with CT or more preferably MRI is indicated.
