“…Some studies have used CAD systems to classify breast masses by elastography, although without employing the BI-RADS lexicon classification and without comparing the best cutoff values (7,18) . In the study conducted by Zhang et al (7) , a cutoff value of 80% hard areas was used but the authors adopted a 5-point classification system (7,19) . In the present study, cutoff values of 70%, 80%, and 90% hard areas were initially tested in the areas segmented by the radiologists.…”

Objective: To determine the best cutoff value for classifying breast masses by ultrasound elastography, using dedicated software for strain elastography, and to determine the level of interobserver agreement. Materials and Methods: We enrolled 83 patients with 83 breast masses identified on ultrasound and referred for biopsy. After B-mode ultrasound examination, the lesions were manually segmented by three radiologists with varying degrees of experience in breast imaging, designated reader 1 (R1, with 15 years), reader 2 (R2, with 2 years), and reader 3 (R3, with 8 years). Elastography was performed automatically on the best image with computer-aided diagnosis (CAD) software. Cutoff values of 70%, 75%, 80%, and 90% of hard areas were applied for determining the performance of the CAD software. The best cutoff value for the most experienced radiologists was then compared with the visual assessment. Interobserver agreement for the best cutoff value was determined, as were the interclass correlation coefficient and concordance among the radiologists for the areas segmented. Results: The best cutoff value of the proportion of hard area within a breast mass, for experienced radiologists, was found to be 75%. At a cutoff value of 75%, the interobserver agreement was excellent between R1 and R2, as well as between R1 and R3, and good between R2 and R3. The interclass concordance coefficient among the three radiologists was 0.950. When assessing the segmented areas by size, we found that the level of agreement was higher among the more experienced radiologists. Conclusion: The best cutoff value for a quantitative CAD system to classify breast masses was 75%.

“…The general characteristics of mammary gland masses were examined by routine ultrasound for size, shape, location, boundary, aspect ratio, echo, and whether or not there was attenuation and calcifications. RTE-graded elastic images were judged according to the Tsukuba Elasticity Score, [14] as follows: 1 point, the entire mases was green, 2 points, the masses were a mosaic of green and blue, 3 points, the peripheral areas of the masses were green and the center was blue, 4 points, the entire mass was blue, and 5 points, both the mass and the surrounding tissue were blue. The elasticity images were diagnosed as benign with a score of 1-3 points and malignant with a score of 4-5 points.…”

Background: To evaluate the application of three elastography methods including real-time tissue elasticity imaging (RTE), strain rate ratio elasticity imaging (SR), and acoustic radiation force elastic imaging (ARFI) in two ultrasound instruments for the diagnosis of benign and malignant breast lesions. Materials and Methods: The authors examined 97 breast nodules of 97 patients who were ready to undergo adenomammectomy. For each patient, RTE was applied to determin nodule properties by level 5 score method, SR was applied to measure the strain rate ratio of targeted nodules, and the surrounding mammary glands at the same level, ARFI was applied to measure internal and marginal shear wave velocity (SWV) values of targeted nodules. Results: The sensitivity and specificity of RTE, SR, the internal SWV values, and marginal SWV values were more than 80% in diagnosing breast nodules. Area under the curve of RTE, SR, the internal SWV values, and the marginal SWV values in diagnosis of benign and malignant breast nodules were 0.923, 0.934, 0.934 and 0.916, respectively. No significant differences were found among the four values for the diagnosis efficiency. Conclusions: RTE, SR, and ARFI are all highly valuable in diagnosing benign and malignant breast nodules.

“…On the other hand, at T18, shown in Figure 4c, the bulb appears to be a more uniform soft tissue with less strain on elasticity imaging compared to the previous timepoint. Regarding elasticity, Fujifilm established standards by using breast tissue as a sample [14]. According to these standards, Tsukuba Elasticity Score 1 indicates strain throughout the entire hypoechoic area, Score 2 indicates an absence of strain in part of the hypoechoic area, Score 3 indicates strain in the marginal zone without strain in the center of the hypoechoic area, Score 4 indicates strain throughout the entire hypoechoic area, and Score 5 indicates a complete absence of strain [14].…”

This case report describes the successful treatment of refractory vesicourethral anastomosis (VUA) pain in an 82-year-old man following radical prostatectomy using a combination of non-ablative erbium:YAG and neodymium:YAG laser therapy with Fotona SP Dynamis. Despite various conventional treatments, the patient's pain persisted, which significantly impaired his quality of life. The rationale for using laser therapy is based on its potential to promote tissue healing and nerve regeneration and reduce inflammation at the anastomosis site. The patient underwent monthly laser irradiation sessions, with the erbium:YAG laser targeting the area around the urethral anastomosis site via the anus and the neodymium:YAG laser irradiating the base of the penis and scrotum. Urethral pain gradually decreased from a visual analog scale score of 10 to 0 over the course of treatment. This highlights the importance of considering alternative approaches when conventional methods fail to provide relief. The targeted, minimally invasive nature of laser therapy may offer a safer and more effective alternative to systemic medications for managing chronic post-surgical pain. Although further research is needed to establish the generalizability and long-term effectiveness of this approach, this case provides a promising foundation for future investigations of the role of laser therapy in managing refractory VUA pain following radical prostatectomy.
