“…It has been demonstrated that cadaver laboratories improve surgical residents' ability to perform and interpret FAST examinations . It has also been demonstrated that the use of phantom models is realistic for teaching breast US imaging to surgical residents, and that training in US‐guided breast biopsies improves patient safety and accuracy . Additionally, it has been demonstrated that the use of a mannequin and associated computer simulation system for training compares favorably with the more traditional hands‐on approach using patients …”

The use of point-of-care ultrasound (US) in the clinical setting has undergone massive growth, although its incorporation into training and practice is variable. Surgeons are interested in using point-of-care US and can incorporate it effectively into clinical practice. However, the current state of point-of-care US training in general surgery is inadequate. The Accreditation Council for Graduate Medical Education introduced the Milestones Project to evaluate resident and fellow performance. Emergency medicine is the only specialty with a point-of-care US milestone. We have successfully implemented a US training program into our general surgery residency curriculum and now propose milestones in point-of-care US for all general surgery residents.

“…This makes it possible to visualize direction-dependent ultrasonic tomograms similar to those expected from actual patients. In previous studies, phantoms using tofu, (2) gelatin, (3) agar, (1,4) silicone, (5) and cadavers (6) have been reported; however, in this study, silicon-based materials were used in consideration of cost and long-term availability.…”

Fine needle aspiration cytology (FNAC) is commonly used and is essential for diagnosing thyroid diseases. Despite its widespread use, it presents a significant barrier for doctors who lack experience with this procedure, owing to the inherent difficulty involved in identifying and avoiding venous arteries such as the internal jugular vein, common carotid artery, and trachea. At this stage, a universal neck simulator supporting FNAC practice has yet to be developed. This project is based on an earlier simulator developed by the authors. However, a number of significant improvements have been made to bring this closer to what could be potentially a practical simulator for thyroid FNAC practice. Improvements have been made in terms of the accuracy of the organs and the addition of muscle tissue, but the most significant issue is the use of a material that does not require special storage, namely, silicone mixed with a number of compounds as required to sonographically and haptically simulate the neck and thyroid.

“…We used breast phantom, which enables multi-reader analysis for the same lesion. There have been several papers discussing breast phantom as a tool for breast US training (15)(16)(17)(18), but this is the first study to directly apply breast phantom for reliability studies for breast CAD system. In our conclusion, there was better agreement of lexicons and final assessment in US than in CAD.…”

Reliability Studies of Different Readers Using Computer Aided Diagnosis System in Ultrasound for Determining Identical Lesions in a Breast Phantom

Background: The computer-aided diagnosis (CAD) has been applied in multiple studies conducted recently in order to perform ultrasound (US) of the breast. There are several studies that have indicated that CAD is useful for improving the diagnostic performance in less experienced radiologists. However, there is no study on several readers analyzing the same lesions using a breast phantom and rare reliability studies. Objectives: To investigate the reliability of different readers using computer aided diagnosis (CAD) system in US for determining identical lesions in a breast phantom. Patients and Methods: From March 2016 to February 2017, six readers (three senior and three junior residents in the department of radiology) evaluated and analyzed breast phantom including 14 lesions. At the first line study, three senior residents (3rd grade with more than one month of training for breast ultrasound [US]) and three junior residents (1st grade without breast US training) evaluated and analyzed the US and applied CAD for lesions in breast phantom, and they were able to make final decisions by subjective combination. A month later, they conducted the second line study as they did the first line study. We analyzed the inter-and intra-reader reliability and accuracy of US, CAD, and combinations (subjective, conjunctive, and disjunctive). Results: In the total of first and second line studies of six readers, the kappa value of US (0.609) was significantly higher than CAD (0.411). In the subjective combined conclusion, the kappa value was improved by the junior group. In the whole inter-and intrareader analysis, the kappa values of final assessment of the senior and junior group were more variable on CAD than on US, especially in the junior group, and this result was statistically significant. The area under the curve (AUC) of US, CAD, subjective, conjunctive, and disjunctive combination in seniors were all better than those of juniors. In all groups, the AUCs, sensitivities, and specificities were improved on conjunctive combined US with CAD. Conclusion: The combination US with CAD improved the reliability and diagnostic performance. The CAD results of the junior group were variable and inconsistent. Therefore, minimum training and experience for breast US is indispensable for the better use of breast CAD, and, combination US with CAD is useful for all readers.
