Abstract
Introduction The diagnosis of lung cancer, as well as that of lung nodules, is increasing. Percutaneous biopsy has become a transcendental tool for its diagnosis. Traditionally, computed tomography is used for these procedures because of its ability to clearly demonstrate bone and aerated lung. However, in selected cases it can be performed with ultrasound. Methods Retrospective study conducted between January 2020 and December 2021, during the SARS-CoV-2 pandemic. All patients had pleural-based lung lesions or pleural lesions, some with a known history of cancer. Results Thirty-six procedures were performed, in 32 (88.9%) the sample obtained presented diagnostic yield and the most used additional test was Immunohistochemistry in 23 (63.9%). Complications were reported in 5 patients (13.9%): 2 with mild pneumothorax, 2 with hemothorax (1 mild and 1 moderate) and 1 patient reported pain. Conclusion Ultrasound is a valid method to be used as a guide for biopsies of pleural and peripheral pulmonary lesions. The complications and diagnostic rate has been shown to be in line with the experience of other authors and international guidelines.

Expert Rev Respir Med 2023; 17:805-813. [PMID: 37787485 DOI: 10.1080/17476348.2023.2266377] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2023] [Accepted: 09/29/2023] [Indexed: 10/04/2023]
Abstract
BACKGROUND Real-time thoracic ultrasound-guided pleural biopsy (TUSPB) is an important diagnostic method for pleural diseases. Traditional two-dimensional thoracic ultrasound, as well as newly developed contrast-enhanced ultrasound (CEUS) and ultrasound elastography (UE), are all used as guidance tools for pleural biopsies. Herein, we aimed to determine the diagnostic yield of real-time TUSPB for pleural diseases to better inform the decision-making process. METHODS A literature search of the MEDLINE/PubMed, Embase, and Cochrane Library databases was performed up to June 2023. A binary random-effects model was applied to determine the pooled diagnostic yield. RESULTS Fifteen studies comprising 1553 patients with pleural diseases were included and analyzed. The overall diagnostic yield of TUSPB for pleural diseases was 85.58% (95% confidence interval [CI]: 81.57-89.58%). The sensitivity was 77.56% for pleural malignancy and 80.13% for tuberculous pleurisy. The sub-analysis result revealed that CEUS-guided pleural biopsy provided a pooled diagnostic yield of 98.24%, which was higher than that of conventional TUSPB (78.97%; p < 0.01). The overall proportion of adverse events for TUSPB was 6.68% (95% CI: 5.31-8.04%). CONCLUSION Conventional TUSPB has good pooled diagnostic yields and high safety. CEUS and UE are promising guidance tools for pleural biopsy with the potential to increase diagnostic yield.

Abstract
AIM To explore the factors that influence sample adequacy and safety of ultrasound (US)-guided biopsy for peripheral pulmonary lesions (PPLs) with 16-G needles. MATERIALS AND METHODS A total of 263 patients (150 men, 113 women; mean age, 60.7 ± 13 years) who received US-guided biopsy for PPLs with 16-G needles from July 2017 to March 2021 were included. Variables including patient demographics, lesion location, lesion size, proportion of lesion necrosis, presence of emphysema, presence of bullae around lesion, patient position, and number of needle passes were recorded. Univariate analysis and multivariable logistic regression analysis were performed to explore the factors that influence sample adequacy and safety. RESULTS Biopsy specimens were adequate for diagnosis in 242/263 (92%) cases. Multivariable logistic regression analysis revealed lesion size was significantly associated with sample adequacy (p=0.005, odds ratio [OR] = 1.039). The incidence of overall complication rate was 10.6% (28/263), including pneumothorax and haemorrhage, which occurred in 2.7% (7/263) and 9.9% (26/263) of patients, respectively. Patient position (lateral versus supine) was associated with overall complication rates (p=0.029, OR=3.407) and haemorrhage (p=0.013, OR=4.870). The presence of bullae around the lesion (p=0.026, OR=73.128) was an independent factor associated with pneumothorax. CONCLUSION US-guided percutaneous biopsy for PPLs with 16-G needles is effective and safe. Sample adequacy is significantly affected by lesion size. Patient lateral position is a risk factor for overall complication and haemorrhage. The presence of bullae around the lesion is a predictor of pneumothorax.

Abstract
OBJECTIVES To explore the feasibility of contrast-enhanced ultrasound (CEUS) as a new tool for characterizing vascularization of primary peripheral lung cancer. METHODS 315 consecutive patients with definite primary peripheral lung cancers underwent CEUS examination from November 2016 to March 2022. CEUS parameters including time to enhancement (TE), time to peak (TP), time to wash-out (TW), distribution of vessels (DV), extent of enhancement (EE) and homogeneity of enhancement (HE) were obtained. RESULTS The lesions were grouped on the basis of TE which reflects tumor vascularization: early enhancement (pulmonary arterial vascularization) (n = 91) and delayed enhancement group (bronchial arterial vascularization) (n = 224). Overall, lung tumors commonly (71.1%) manifested a delayed enhancement which indicating blood supply originated from bronchial arteries, while an early enhancement was present in less than a third of the cases. Tumors with bronchial vascularization tended to show a delayed, reduced and heterogeneous enhancement. Correspondingly, it is characterized by a shorter TE, marked EE and a relatively infrequent occurrence of necrosis in tumors with pulmonary vascularization. CONCLUSIONS Providing micro-perfusion information, CEUS is a potentially imaging tool for evaluating blood supply in primary peripheral lung cancer.

[PMID: 36140476 PMCID: PMC9497473 DOI: 10.3390/diagnostics12092074] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2022] [Revised: 08/16/2022] [Accepted: 08/24/2022] [Indexed: 11/20/2022] Open
Abstract
Background: Subpleural focal organizing pneumonia (FOP) and primary lung malignancy (PLM) are usually confused. The aim of this study was to explore the value of ultrasound (US) and contrast-enhanced ultrasound (CEUS) in the differential diagnosis of FOP and PLM. Methods: A total of 23 patients (mean age: 64.57 ± 11.86 years) with FOP and 100 (mean age: 66.29 ± 11.05 years) with subpleural lesions diagnosed as PLM, confirmed by pathological diagnosis and clinical follow-up, were retrospectively enrolled. The largest lesion diameter, angle between the lesion border and thoracic wall, air bronchial sign, internal blood supply, blood supply form, and pleural effusion examined using conventional US were retrospectively analyzed. The indicators of CEUS included the arrival time of contrast agent in the lesion, lesion−lung arrival time difference, degree of enhancement, distribution uniformity of contrast medium, presence of non-enhancing region, and arterial filling mode in the lesion. A p < 0.05 was considered statistically significant. Results: Presence of air bronchial sign (odds ratio [OR] = 6.18, p = 0.025), acute angle between the lesion border and thoracic wall (OR = 7.124, p = 0.033), and homogeneous enhancement (OR = 35.26, p = 0.01) showed predictive value for the diagnosis of FOP. According to the results of the logistic regression analysis, the area under the receiver operating curve of the above features combined was 0.960, and the sensitivity and specificity were 95.0% and 82.6%, respectively. Conclusions: US combined with CEUS has the potential to differentiate between FOP and PLM.

Abstract
INTRODUCTION Peripheral pulmonary lesions are encountered frequently in clinical practice. Accurate diagnosis of these lesions is of great importance for clinicians. Ultrasound-guided lung tissue puncture is a reliable method for diagnosing these lesions. OBJECTIVES To investigate the application value of contrast-enhanced ultrasound (CEUS) combined with rapid on-site evaluation (ROSE) in the diagnosis of peripheral pulmonary focal lesions. METHODS Eighty patients enrolled from July 2020 to June 2021 were divided into two groups: a conventional ultrasound group and a CEUS group. Both groups underwent diagnostic procedures guided by ROSE to improve the success rate of puncture sampling. The success rates and complications in both groups were compared. The results for lesion enhancement, time taken for the contrast agent to reach the lesions (AT) and lung tissues (L-AT), and the difference between these times (∆AT) were compared in the CEUS group. RESULTS The success rate of biopsy in the CEUS group was 97.62%, which was significantly higher than that in the conventional ultrasound group (84%; P < .05). Puncture complications did not occur in the CEUS group and occurred in 5.26% of the cases in the conventional ultrasound group, but the difference was not statistically significant (P > .05). A comparison of enhancement of benign lesions and malignant lesions in the CEUS group showed a statistically significant difference (P < .05). The difference between the AT and ∆AT of benign and malignant lesions was statistically significant (P <.05). The optimal threshold of ∆AT was 2.05 s. CONCLUSION CEUS combined with ROSE is a very important approach for biopsy in the diagnosis of peripheral pulmonary focal lesions. CEUS has definite clinical value in the diagnosis of benign and malignant lung lesions.

Abstract
OBJECTIVE To explore the clinical value of contrast-enhanced ultrasound (CEUS) in the differential diagnosis of benign and malignant subpleural pulmonary lesions (SPLs). METHODS Among 959 patients with SPLs who were scheduled to undergo ultrasound-guided puncture in our department between January 2019 and June 2019, 506 patients were included and their B-mode ultrasound and CEUS features, including the lesion's location, size, margin, echo, perfusion pattern of ultrasound contrast agent, degree of enhancement, homogeneity, vascular signs, and necrosis, were retrospectively investigated. All malignant cases were diagnosed by pathology, while benign cases were diagnosed by two respiratory physicians after comprehensive analysis of pathology, etiology, imaging, and clinical symptoms. Statistical differences in these features between the benign and malignant groups were then analyzed. RESULTS There were 506 cases in this study, including 219 benign cases and 287 malignant cases. Among them, 351 were males and 155 were females, with an average age of 59 ± 16 years. There were statistically significant differences between benign and malignant groups in the perfusion pattern, the degree of enhancement, and vascular signs. The features of the malignant group included local-to-whole perfusion pattern, hypo-enhancement, and curly hair sign, while those of the benign group included a centrifugal perfusion pattern, iso-enhancement and hyper-enhancement, and dendritic sign. There was no statistically significant difference between the two groups in homogeneity and necrosis. CONCLUSIONS CEUS enhancement mode is different between benign and malignant SPLs, which can provide supplementary information for the differential diagnosis of SPLs in the existing imaging diagnosis.

Abstract
The use of ultrasound has revolutionized the evaluation of pulmonary complaints and pathology. Historically, most lung ultrasound uses described are limited to B-mode, M-mode and occasionally color Doppler. However, the use of contrast can significantly expand the diagnostic capabilities of lung ultrasound. Ultrasound contrast enables significant expansion of therapeutic and intervention capabilities. We provide a detailed description of contrast administration, phases and uses in lung ultrasound. Additionally provided are example contrast use cases and illustrative examples of contrast use in a wide range of lung ultrasound applications including pneumonia, atelectasis, pulmonary embolism and neoplasms. Clinical practice examples will help providers incorporate contrast use into their lung ultrasound practice.

Abstract
Contrast-enhanced ultrasound (CEUS) for the differentiation of benign and malignant peripheral pulmonary lesions has been considered experimental for many years. This study was aimed at evaluating the feasibility of CEUS as a diagnostic modality in this area of discussion. CEUS diagnostic accuracy was explored by comparison with contrast-enhanced computed tomography (CECT). The collective included 449 patients with 449 definitive diagnoses (benign, 178; malignant, 271). Logistic regression analysis of CEUS data revealed that delayed time to enhancement, chaotic pattern of distribution of vessels and mild extent of enhancement were independent risk factors for predicting malignancy. Time to wash-out and homogeneity of enhancement did not differ between the two groups (p > 0.05). Based on histopathology or clinical follow-up as a reference standard, CEUS and CECT had similar diagnostic accuracies of 80.16% and 81.75%, respectively. CEUS is a potentially useful imaging tool for diagnosing peripheral pulmonary lesions.

Abstract
Ultrasonography is a very good tool for guiding different interventional procedures in the chest. It is the ideal technique for managing conditions involving the pleural space, and it makes it possible to carry out procedures such as thoracocentesis, biopsies, or drainage. In the lungs, only lesions in contact with the costal pleura are accessible to ultrasound-guided interventions. In this type of lung lesions, ultrasound is as effective as computed tomography to guide interventional procedures, but the rate of complications and time required for the intervention are lower for ultrasound-guided procedures.

Abstract
To evaluate the application of machine learning for the detection of subpleural pulmonary lesions (SPLs) in ultrasound (US) scans, we propose a novel boundary-restored network (BRN) for automated SPL segmentation to avoid issues associated with manual SPL segmentation (subjectivity, manual segmentation errors, and high time consumption). In total, 1612 ultrasound slices from 255 patients in which SPLs were visually present were exported. The segmentation performance of the neural network based on the Dice similarity coefficient (DSC), Matthews correlation coefficient (MCC), Jaccard similarity metric (Jaccard), Average Symmetric Surface Distance (ASSD), and Maximum symmetric surface distance (MSSD) was assessed. Our dual-stage boundary-restored network (BRN) outperformed existing segmentation methods (U-Net and a fully convolutional network (FCN)) for the segmentation accuracy parameters including DSC (83.45 ± 16.60%), MCC (0.8330 ± 0.1626), Jaccard (0.7391 ± 0.1770), ASSD (5.68 ± 2.70 mm), and MSSD (15.61 ± 6.07 mm). It also outperformed the original BRN in terms of the DSC by almost 5%. Our results suggest that deep learning algorithms aid fully automated SPL segmentation in patients with SPLs. Further improvement of this technology might improve the specificity of lung cancer screening efforts and could lead to new applications of lung US imaging.

Diagnostics (Basel) 2021; 11:diagnostics11071293. [PMID: 34359376 PMCID: PMC8305637 DOI: 10.3390/diagnostics11071293] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2021] [Revised: 07/12/2021] [Accepted: 07/14/2021] [Indexed: 12/19/2022] Open
Abstract
Purpose: To evaluate the value of CEUS in differentiating malignant from benign pleural effusions (PEs). Methods: From 2008 to 2017, 83 patients with PEs of unknown cause were examined using B-mode thoracic ultrasound (B-TUS), CEUS, and cytological examination. The extent of enhancement of the pleural thickening, the presence of enhancement of septa or a solid mass within the PE, and the homogeneity of the enhancement in the associated lung consolidation, were examined. Subsequently, the diagnostic value of cytology, B-TUS, and CEUS in differentiating malignant from benign PEs was determined. Results: With CEUS, markedly enhanced pleural thickening and inhomogeneous enhanced lung consolidation were significantly more frequently associated with malignancy (p < 0.05). In the subgroup analysis, the use of CEUS increased the sensitivity from 69.2 to 92.3 in patients with initial negative cytology but clinical suspicion of malignant PE; it also increased the specificity from 63.0 to 90.0, the positive predictive value from 69.2 to 92.3, the negative predictive value from 63.0 to 90.0, and the diagnostic accuracy from 66.7 to 87.5, in the evaluation of PE malignancy. Conclusion: The use of clinically based B-TUS and CEUS as a complementary method to cytological evaluation may be beneficial for evaluating a PE of unknown cause. CEUS patterns of enhanced pleural thickening and inhomogeneous enhanced lung consolidation may suggest a malignant PE.

Abstract
Objective To evaluate the accuracy and safety of contrast-enhanced ultrasound (CEUS) guided biopsy in the diagnosis of radiologically determined pleural based lesions. Method A prospective study was conducted on patients with radiologically determined pleural based lesions. Patients who met the inclusion criteria received pleural biopsy guided by CEUS to obtain specimens, followed by histomathological and microbiological examinations. After treatment and follow-up, surgical thoracoscopy was performed on cases with undefinite diagnosis. Result A total of 460 patients were finally included. CEUS showed internal necrosis in 72.17% cases and obvious peripheral vessels in 55.43% cases, both of which were significantly higher than the conventional ultrasound imaged (p < 0.05). The diagnostic accuracy through CEUS guided biopsy sampling was 98.91% (455/460). The microbiological diagnostic yield achieved 71.88% (225/313) in infectious lesions. In 330 cases combined pleural effusion, CEUS guided biopsy increased the diagnostic yield from 60.30% (199 /330) to 98.36% (325 /330) in all cases (p < 0.05), from 15.56% (14/90) to 94.44% (85/90) in malignant lesions (p < 0.01) and from 77.08% (185/240) to 100% (240/240) in infectious lesions (p < 0.05). No serious adverse events occurred. Conclusion CEUS guided biopsy provides a minimally invasive, effective and safe diagnostic biopsy method for pleural lesions.

Ultrasound-Guided Percutaneous Core Needle Biopsy of Peripheral Pulmonary Nodules ≤ 2 cm: Diagnostic Performance, Safety and Influence Factors. Front Oncol 2021; 11:671884. [PMID: 34055640 PMCID: PMC8160365 DOI: 10.3389/fonc.2021.671884] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2021] [Accepted: 04/16/2021] [Indexed: 12/28/2022] Open
Abstract
Purpose To evaluate diagnostic performance and safety of ultrasound-guided needle biopsy in the diagnosis of peripheral pulmonary nodules (PPLs) ≤ 2 cm, and the influence factors of sample adequacy and safety. Materials and Methods 194 patients (99 men, 95 women; mean age, 56.2 ± 13.7 years) who received biopsy for PPLs ≤ 2 cm between January 2014 to January 2019 were included. Variables including patient demographics, lesion location, lesion size, presence of lesion necrosis, presence of emphysema on CT, patient position, biopsy needle size and number of needle passes were recorded. Univariate analysis and multivariate logistic regression analysis were performed to explore the influence factor of sample adequacy and safety. Results Biopsy specimens were adequate for diagnosis in 161/194 (83%) cases; the diagnostic accuracy was 81.4% (158/194). The overall complication rate was 8.8% (17/194), including pneumothorax, hemoptysis and pleural effusion, which occurred in 2.1% (4/194), 5.2% (10/194), and 1.5% (3/194) of patients, respectively. The incidence of pneumothorax in the 16-gauge-needle group were significantly higher than that of the 18-gauge-needle group (5.6% vs 0%, P=0.018). Adequate sampling of 16-gauge and 18-gauge needles were achieved in 90.3%(65/72) and 78.7%(96/122) cases, respectively. Multivariate logistic regression analysis revealed needle size (16-gauge vs 18-gauge) was an independent influence factors of sample adequacy (P=0.015, odds ratio=3.419). A receiver operating characteristic curve was plotted and the area under the curve was 0.774. Conclusion US-guided percutaneous needle biopsy is a feasible and safe technique for small PPLs ≤ 2 cm. Needle size is an independent influence factor of sample adequacy and post-procedure pneumothorax. Sixteen-gauge needle has the advantage of achieving adequate sample for pathological analysis, though the risk of pneumothorax should be alerted.

Abstract
BACKGROUND A 3-year prospective study was conducted to evaluate the efficacy of Xpert MTB/RIF (Xpert) in the diagnosis of pleural tuberculosis (pTB) on contrast -enhanced ultrasound (CEUS)-guided pleural biopsy specimens. METHOD Patients suspected with pTB were prospectively enrolled to receive CEUS-guided biopsy. Specimens (pleural tissue and fluid) were submitted for Xpert and other routine examinations. Surgical thoracoscopy was performed on undiagnosed cases. RESULT A total of 316 patients were enrolled, including 280 cases of pTB (definite 195, possible 85) and 36 cases of non-pTB. The sensitivity of Xpert was 69.64% (195/280) in biopsy specimens, which was significantly higher than that in pleural effusion specimens (p < 0.01). In 195 definite cases, the highest sensitivity of 100% (195/195) and NPV of 29.75% (36/121) were achieved by Xpert on biopsy specimens. Xpert-positive results were obtained in 149 culture-negative cases and 90 histopathological MTB PCR-negative cases. The incidence of necrosis by CEUS in Xpert-positive pTB was significantly higher than that in Xpert-negative pTB (χ2 = 72.41; p < 0.01). No serious complications occurred. CONCLUSION Xpert achieved highly diagnostic sensitivity in pTB through CEUS-guided biopsy sampling, especially on necrotic lesions, which was proven to be efficient, minimally invasive and safe.

Abstract
The purpose of this study was to investigate the role of contrast-enhanced ultrasound (CEUS) in determining the viable target area in patients with subpleural pulmonary lesions before ultrasound-guided transthoracic core biopsy. In this retrospective study, we analyzed 92 patients with subpleural pulmonary lesions (63 males and 29 females; mean age: 65.17 ± 11.72 y). All patients underwent B-mode ultrasound, color Doppler and CEUS. Color Doppler was performed to identify the major vessels. The time to enhancement of the contrast agents, homogeneity of enhancement and the presence of areas without enhancement were recorded after administration of the contrast agents. The viable target areas were defined as regions showing enhancement relative to those without enhancement and regions showing delayed enhancement in reference to peripheral lung tissues showing early enhancement. Afterward, real-time ultrasound-guided transthoracic core needle (18 gauge) biopsies were performed and the complication rate, success rate and diagnostic accuracy were calculated. With CEUS, the needle pathways of these lesions were readjusted the biopsy strategy in 40/92 patients (43.5%). It was determined that the satisfactory rate of the subsequent biopsy specimen was 100%. The histologic diagnostic accuracy of the biopsy was 97.83%. No serious complications occurred during the biopsy. In conclusion, the application of CEUS before biopsy was able to depict the viable target areas of the lesion to readjust the biopsy routes. With the help of CEUS, ultrasound-guided core biopsy could obtain adequate samples, improve the diagnostic accuracy and reduce the complication rates of biopsies.

Propensity-score-matching analysis to compare efficacy and safety between 16-gauge and 18-gauge needle in ultrasound-guided biopsy for peripheral pulmonary lesions. BMC Cancer 2021; 21:390. [PMID: 33836683 PMCID: PMC8034192 DOI: 10.1186/s12885-021-08126-7] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2020] [Accepted: 03/25/2021] [Indexed: 12/26/2022] Open
Abstract
Background Definitive diagnosis of peripheral pulmonary lesions (PPLs) depends on the histological analysis of the pleural biopsy sample. Ultrasound (US)-guided sampling is now standard practice in the clinical setting. However, determining a suitable needle size and sampling times to improve the efficacy and safety of the biopsy remains challenging. Here, we compared the efficacy between 16- and 18-gauge core biopsy needles in US-guided percutaneous transthoracic biopsy for PPLs on histological diagnosis and procedure-related complications. Materials and methods In total, 1169 patients (767 men, 402 women; mean age, 59.4 ± 13.2 years) who received biopsy for PPLs between September 2011 and February 2019 were included. The propensity score matching (PSM) analysis was performed to adjust the baseline differences, and the rate of successful specimen assessment and complications were compared between the 16-gauge (249 patients) and 18-gauge (920 patients) groups. The number of pleural surfaces crossed (NOPSC) was defined as the number of times the visceral pleural surface was transgressed. Stratified analysis was performed based on NOPSC. Results The overall success rate was 92.0% (1076/1169). The overall complication rate was 9.6%, including pneumothorax, hemorrhage, and vasovagal reaction, which occurred in 2.5% (29/1169), 6.6% (77/1169), and 0.5% (6/1169) of the patients, respectively. When NOPSC was 1 or > 2, the success and complication rates in the 16-gauge group were comparable to those of the 18-gauge group (all P > 0.05). When the NOPSC was 2, the success rate in the 16-gauge group was significantly higher than that in the 18-gauge group (P = 0.017), whereas the complication rate was comparable (P > 0.05). Conclusion Higher success rate could be achieved using a 16-gauge than an 18-gauge core biopsy needle in the US-guided percutaneous transthoracic biopsy for PPLs when the NOPSC was 2. We recommend using 16-gauge needles with 2 times of needle passes in biopsy for PPLs in clinical practice.

Abstract
Lung cancer is one of the commonest malignancies worldwide and necessitates both early and personalised treatment. A key requirement is histological sampling with immunohistochemistry obtained usually from percutaneous biopsy. Conventionally thoracic biopsies are performed using CT guidance, but more recently, there has been development of physician led ultrasound biopsy for pleural lesions. Contrast-enhanced ultrasound (CEUS) has been increasingly used in interventional procedures and is able to offer benefits for thoracic biopsies including improving lesional visualisation and characterisation, targeting viable tissue and avoiding critical vascular structures as well as evaluating for the presence of post-procedural complications. This educational review aims to benefits of the role of CEUS in thoracic biopsies.

Abstract
INTRODUCTION Congenital cystic adenomatoid malformation (CCAM) is a rare developmental lung abnormality, that typically manifests in neonates and infants but rarely in adults. Ultrasound is an important method of diagnosing CCAM in neonates and infants; however, few articles have reported the value of transthoracic lung ultrasound in the diagnosis of CCAM in adults. PATIENT CONCERNS We present a case of a 34-year-old woman with a cavitary lesion in her left lower lobe, that suggested chronic inflammation. DIAGNOSIS The patient underwent ultrasound examination and contrast-enhanced ultrasound-guided transthoracic core biopsy; histology suggested the diagnosis of lung hamartoma. Surgical resection of the lesion followed by histopathological analysis confirmed the diagnosis of CCAM. INTERVENTIONS The patient underwent transthoracic core biopsy under contrast-enhanced ultrasound guidance. A left lower lobectomy was then performed subsequently. OUTCOMES The patient had a smooth recovery and remained asymptomatic during the 12-months of postoperative follow-up. CONCLUSION We report a rare case of CCAM to suggest that transthoracic ultrasound combined with contrast-enhanced ultrasound is a safe and effective method of diagnosing the subpleural lung malformations in adults, thereby avoiding multiple radiation exposures and associated complications.

Abstract
Near-infrared (NIR) fluorescence imaging (FI) has become a research hotspot because of its distinctive imaging properties: high temporal resolution and sensitivity. Especially in recent years, with the research focus of NIR FI shifting to the NIR-II region, which has better imaging performance, it is expected that NIR FI will find significant applications in the field of in vivo imaging. One of the most crucial directions for research into NIR-II FI is the promotion of novel NIR-II fluorophores with superior imaging properties. The remarkable advantages of organic NIR-II fluorophores in biosafety make them more promising than other fluorescent materials in certain applications. But serious defects in their fluorescence performance preclude particular imaging effects and limit imaging functions. In this review, we summarize and discuss the recent leading literature on overcoming the defects of organic NIR-II fluorophores, demonstrating the potential for further improving their imaging properties. In addition, we cover the functions of NIR-II FI that are promoted by the development of fluorophores, notably including its outlook on molecular imaging in vivo.
