Metastatic Lymph Node Detection on Ultrasound Images Using YOLOv7 in Patients with Head and Neck Squamous Cell Carcinoma. Cancers (Basel) 2024; 16:274. [PMID: 38254765 PMCID: PMC10813890 DOI: 10.3390/cancers16020274] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2023] [Revised: 12/28/2023] [Accepted: 01/04/2024] [Indexed: 01/24/2024] Open
Abstract
Ultrasonography is the preferred modality for detailed evaluation of enlarged lymph nodes (LNs) identified on computed tomography and/or magnetic resonance imaging, owing to its high spatial resolution. However, the diagnostic performance of ultrasonography depends on the examiner's expertise. To support the ultrasonographic diagnosis, we developed YOLOv7-based deep learning models for metastatic LN detection on ultrasonography and compared their detection performance with that of highly experienced radiologists and less experienced residents. We enrolled 462 B- and D-mode ultrasound images of 261 metastatic and 279 non-metastatic histopathologically confirmed LNs from 126 patients with head and neck squamous cell carcinoma. The YOLOv7-based B- and D-mode models were optimized using B- and D-mode training and validation images and their detection performance for metastatic LNs was evaluated using B- and D-mode testing images, respectively. The D-mode model's performance was comparable to that of radiologists and superior to that of residents' reading of D-mode images, whereas the B-mode model's performance was higher than that of residents but lower than that of radiologists on B-mode images. Thus, YOLOv7-based B- and D-mode models can assist less experienced residents in ultrasonographic diagnoses. The D-mode model could raise the diagnostic performance of residents to the same level as experienced radiologists.

[PMID: 36846436 PMCID: PMC9948592 DOI: 10.1002/lio2.995] [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: 08/13/2022] [Revised: 11/14/2022] [Accepted: 12/04/2022] [Indexed: 12/24/2022] Open
Abstract
Objectives The American Academy of Otolaryngology clinical practice guidelines recommend cross-sectional imaging or fine needle aspiration for any neck mass in an adult that persists beyond 2 weeks that is not convincingly related to a bacterial infection. We aimed to assess the role of ultrasound in the evaluation and management of neck masses. Methods A retrospective chart review was performed of adult patients evaluated in the Otolaryngology clinic at a single institution from December 2014 to December 2015 for a visible or palpable neck mass persistent beyond 2 weeks who had an ultrasound exam as part of their initial workup. Patients with a history of head and neck malignancy or those presenting wtih primary salivary or thyroid gland lesions were excluded. Sonographic features, demographics, imaging, and biopsy results were recorded. Results Of the 56 patients who met inclusion criteria, 36 (64.3%) received FNA or biopsy, of which 18 (50%) demonstrated malignant pathology. Twenty patients (35.7%) demonstrated benign features on ultrasound and did not undergo tissue sampling. Two of these 20 patients underwent subsequent cross-sectional imaging. Eight of these 20 patients were followed with serial ultrasound with an average of 3 exams over 14.7 months. The remaining 12 patients had spontaneous resolution of their adenopathy. None of these 20 patients was subsequently diagnosed with malignancy. Conclusion In this study, approximately one third of patients presenting with a visible or palpable neck mass were able to safely avoid cross-sectional imaging and/or tissue sampling when ultrasound demonstrated features consistent with benign pathology. Our results suggest that ultrasound can play a useful role in the initial evaluation and management of adults presenting with a neck mass. Level of Evidence IV.

Abstract
INTRODUCTION Surgeon-performed ultrasound (SUS) for head and neck masses is increasingly being performed by head and neck surgeons. This is the first study assessing its impact in a head and neck surgical oncology clinic, examining the effect on various parameters. METHODS Retrospective analysis was conducted on a database, analysing and comparing all new patients reviewed 6 months prior to (pre-SUS group) and 6 months following (post-SUS group) the introduction of SUS to the outpatient head and neck surgical oncology clinic. The numbers of radiology imaging investigations (ordered through a medical imaging department), fine-needle aspirations (FNAs) performed, clinical appointments and time to definitive treatment decision were analysed and compared. RESULTS A total of 365 patients were included: 169 in the pre-SUS group and 196 in the post-SUS group. There was a statistically significant difference in the number of total radiological imaging investigations performed (1.60 vs. 0.70, p < 0.00001), radiologist-performed FNAs (0.24 vs. 0.10, p = 0.0234), time for definitive treatment decision being made (16.4 days vs. 11.6 days, p = 0.04338), and number of clinical encounters (3.03 vs. 2.29, p < 0.00001). No statistically significant difference was observed in the number of head and neck surgical oncology clinic appointments (1.70 vs. 1.66, p = 0.6672). CONCLUSION Surgeon-performed ultrasound reduces the number of radiological imaging investigations and FNAs performed, reduces time for definitive treatment decision being made, and reduces the number of clinical encounters for patients. This supports its use in head and neck cancer setting and has important implications for both patients and the health-care system.

The use of structured reporting of head and neck ultrasound ensures time-efficiency and report quality during residency. Eur Arch Otorhinolaryngol 2019; 277:269-276. [PMID: 31612337 DOI: 10.1007/s00405-019-05679-z] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2019] [Accepted: 10/01/2019] [Indexed: 02/07/2023]
Abstract
PURPOSE Free text reports (FTR) of head and neck ultrasound studies are currently deployed in most departments. Because of a lack of composition and language, these reports vary greatly in terms of quality and reliability. This may impair the learning process during residency. The purpose of the study was to analyze the longitudinal effects of using structured reports (SR) of head and neck ultrasound studies during residency. METHODS Attending residents (n = 24) of a tripartite course on head and neck ultrasound, accredited by the German Society for Ultrasound in Medicine (DEGUM), were randomly allocated to pictures of common diseases. Both SRs and FTRs were compiled. All reports were analyzed concerning completeness, acquired time and legibility. Overall user contentment was evaluated by a questionnaire. RESULTS SRs achieved significantly higher ratings regarding completeness (95.6% vs. 26.4%, p < 0.001), description of pathologies (72.2% vs. 58.9%, p < 0.001) and legibility (100% vs. 52.4%, p < 0.001) with a very high inter-rater reliability (Fleiss' kappa 0.9). Reports were finalized significantly faster (99.1 s vs. 115.0 s, p < 0.001) and user contentment was significantly better when using SRs (8.3 vs. 6.3, p < 0.001). In particular, only SRs showed a longitudinally increasing time efficiency (- 20.1 s, p = 0.036) while maintaining consistent completeness ratings. CONCLUSIONS The use of SRs of head and neck ultrasound studies results in an increased longitudinal time-efficiency while upholding the report quality at the same time. This may indicate an additive learning effect of structured reporting. Superior outcomes in terms of comprehensiveness, legibility and time-efficiency can be observed immediately after implementation.

Impact of structured reporting on developing head and neck ultrasound skills. BMC MEDICAL EDUCATION 2019; 19:102. [PMID: 30971248 PMCID: PMC6458758 DOI: 10.1186/s12909-019-1538-6] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/07/2018] [Accepted: 03/31/2019] [Indexed: 05/06/2023]
Abstract
BACKGROUND Reports of head and neck ultrasound examinations are frequently written by hand as free texts. This is a serious obstacle to the learning process of the modality due to a missing report structure and terminology. Therefore, there is a great inter-observer variability in overall report quality. Aim of the present study was to evaluate the impact of structured reporting on the learning process as indicated by the overall report quality of head and neck ultrasound examinations within medical school education. METHODS Following an immersion course on head and neck ultrasound, previously documented images of three common pathologies were handed out to 58 medical students who asked to create both standard free text reports (FTR) and structured reports (SR). A template for structured reporting of head and neck ultrasound examinations was created using a web-based approach. FTRs and SRs were evaluated with regard to overall quality, completeness, required time to completion and readability by two independent raters (Paired Wilcoxon test, 95% CI). Ratings were assessed for inter-rater reliability (Fleiss' kappa). Additionally, a questionnaire was utilized to evaluate user satisfaction. RESULTS SRs received significantly better ratings in terms of report completeness (97.7% vs. 53.5%, p < 0.001) regarding all items. In addition, pathologies were described in more detail using SRs (70% vs. 51.1%, p < 0.001). Readability was significantly higher in all SRs when compared to FTRs (100% vs. 54.4%, p < 0.001). Mean time to complete was significantly lower (79.6 vs. 205.4 s, p < 0.001) and user satisfaction was significantly higher when using SRs (8.5 vs. 4.1, p < 0.001). Also, inter-rater reliability was very high (Fleiss' kappa 0.93). CONCLUSIONS SRs of head and neck ultrasound examinations provide more detailed information with a better readability in a time-saving manner within medical education. Also, medical students may benefit from SRs in their learning process due to the structured approach and standardized terminology.

Abstract
Background Reports of head and neck ultrasound examinations are frequently written by hand as free texts. Naturally, quality and structure of free text reports is variable, depending on the examiner’s individual level of experience. Aim of the present study was to compare the quality of free text reports (FTR) and structured reports (SR) of head and neck ultrasound examinations. Methods Both standard FTRs and SRs of head and neck ultrasound examinations of 43 patients were acquired by nine independent examiners with comparable levels of experience. A template for structured reporting of head and neck ultrasound examinations was created using a web-based approach. FTRs and SRs were evaluated with regard to overall quality, completeness, required time to completion, and readability by four independent raters with different specializations (Paired Wilcoxon test, 95% CI) and inter-rater reliability was assessed (Fleiss’ kappa). A questionnaire was used to compare FTRs vs. SRs with respect to user satisfaction (Mann-Whitney U test, 95% CI). Results By comparison, completeness scores of SRs were significantly higher than FTRs’ completeness scores (94.4% vs. 45.6%, p < 0.001), and pathologies were described in more detail (91.1% vs. 54.5%, p < 0.001). Readability was significantly higher in all SRs when compared to FTRs (100% vs. 47.1%, p < 0.001). The mean time to complete a report, however, was significantly higher in SRs (176.5 vs. 107.3 s, p < 0.001). SRs achieved significantly higher user satisfaction ratings (VAS 8.87 vs. 1.41, p < 0.001) and a very high inter-rater reliability (Fleiss’ kappa 0.92). Conclusions As compared to FTRs, SRs of head and neck ultrasound examinations are more comprehensive and easier to understand. On the balance, the additional time needed for completing a SR is negligible. Also, SRs yield high inter-rater reliability and may be used for high-quality scientific data analyses.

Abstract
OBJECTIVES To assess the perspectives of OHNS residents with regards to their training in the following advanced head and neck surgery techniques: transoral robotic surgery (TORS), transoral laser microsurgery (TLM), sialendoscopy, and surgeon-performed ultrasound (SP-US) for possible curricula development. METHODS Cross-sectional survey. A 20-item questionnaire was electronically distributed to OHNS residency programs assessing volume of cases, training barriers, satisfaction, additional training preferences, and pertinence to future practice. RESULTS One hundred thirty-one residents completed the questionnaire. Trainee satisfaction with advanced techniques did not vary significantly with level of training (PGY) or intent to pursue fellowship. Residents who participated in more TLM, sialendoscopy, and SP-US cases were significantly more likely to be satisfied with their training (all p<0.05). The most frequently reported limitation to training was low home institution procedure volume. Seventy-eight of 123 respondents (63.4%) indicated insufficient opportunity to participate in TORS, with most residents reporting that TORS was preferentially performed by attendings (59/78, 75.6%). Forty-five of 126 (35.7%) reported having adequate access to skills training in TORS, compared to 43.6%, 48.4%, and 54.8% for sialendoscopy, TLM, and SP-US, respectively. A vast majority expressed interest in home institution-sponsored training courses in SP-US (120/127, 94.5%) and sialendoscopy (105/129, 81.4%). Many anticipated using SP-US (63.3%) and sialendoscopy (49.6%) in their future practices. CONCLUSION Greater resident participation in advanced head and neck surgical procedures is associated with higher trainee satisfaction. There is a possible need for additional home institution-sponsored training courses, especially in sialendoscopy and SP-US. LEVEL OF EVIDENCE N/A.

Anatomic factors affecting the use of ultrasound to predict vocal fold motion: A pilot study. Am J Otolaryngol 2018; 39:413-417. [PMID: 29678501 DOI: 10.1016/j.amjoto.2018.04.005] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2018] [Revised: 04/04/2018] [Accepted: 04/09/2018] [Indexed: 11/22/2022]
Abstract
PURPOSE Ultrasonography is a well-established modality for visualization of head and neck anatomy. Using ultrasound to detect vocal fold mobility has been described before, but no study has evaluated factors affecting the exam reliability. The aim of the study is to determine anatomic factors influencing the reliability of ultrasound to detect vocal fold motion. Methods and materials Patients underwent ultrasound evaluation and flexible laryngoscopy to assess vocal fold motion from August 2015 to March 2016. Length, accuracy, and clarity of ultrasound examination were assessed, compared to flexible laryngoscopy. For patients with prior neck CT scan imaging, laryngeal anatomy was independently assessed by a blinded neuroradiologist. RESULTS A total of 23 patients, 21 with bilateral vocal fold motion and two with unilateral paralysis, were enrolled. Vocal folds were visible in 19 patients (82%). Eight patients (42%) had good/excellent view and 11 patients (58%) had fair/difficult view. The ultrasound correctly detected absent movement of the vocal fold in the two patients with unilateral paralysis. A total of 19 patients had CT scans, and a linear correlation (r2 = 0.65) was noted between the anterior thyroid cartilage angle measured on CT and the grade of view on ultrasound. CONCLUSION Ultrasound was able to detect vocal fold motion in 82% of randomly screened patients. Ease of detection of vocal fold motion correlated with the anterior thyroid angle. Further studies are warranted to investigate the reproducibility of our results and how this might impact use of ultrasound for detection of vocal fold motion in the operative setting.
