“…Lesion less than 4a is considered as a benign lesion while lesion more than 4a is considered as malignant lesions. The routine sonographic manifestations of level 4 BI-RAD breast lesions tend to have a certain degree of overlapping and are sometimes difficult to judge [12][13][14]. Thus, it is difficult to identify the nature of such lesions in clinic.…”

Abstract. Mammography (MG) is the only proven modality to reduce mortality of breast cancer and has been shown to reduce mortality from breast cancer, and ultrasonography (US) is a well-known adjunct to screening MG. BI-RADS classification is actually practical and correlation with histopathology on the palpable diagnostic cases. To explore the clinical value of combined detection of MG and US BI-RADS in the diagnosis of breast cancer, we examined 212 patients using MG and US (62 cases breast cancer and 150 cases benign leision). All selected cases were re-evaluated by BI-RADS MG alone, US alone, and combined MG and US. In the combined imaging assessment, BI-RADS 1-4a category was MG and US both no more than 4a, however, 4b-5a cacategory was considered as the score of MG and US both more than 4a. MG and US alone findings BI-RADS 1-4a level were 142 cases and 144 cases, respectively; 4b-5 level were 70 and 68, respectively; and for Combination, there were 166 cases 1-4a and 46 cases 4b-5 level. Our results demonstrated that the sensitivity of MG, US alone was 80.65% and 72.58 %, respectly; and specificity was 86.67 % and 84.67%, respectly. The sensitivity of MG and US in combination was 69.35%, however, the specificity was improved into 98.00%, and a positive predictive value was improved into 93.47%. The differences in specificity and positive predictive values between MG and combined imaging assessment, US and combined all were statistically significant (P<0.05). The specificity and positive predictive values of combined assessment was the highest, and the sensitivity and negative predictive values was the highest in the MG assessment. Combined imaging assessment is more effective in diagnosing breast lesions.

“…Gray-scale sonography has become an essential medical tool in the detection and differentiation of breast tumor (22)(23)(24)(25)(26)(27)(28)(29)(30), showing higher sensitivity for breast tumor compared to mammography before surgery (gray-scale sonography, 88%; mammography, 69%) (31). Balu-Maestro et al (15) found that gray-scale sonography was more sensitive than mammography for detecting benign lesions after BCT, but showed almost equal ability to detect IBTR (radiography, 95.5%; sonography, 90.0%).…”

“…The American College of Radiology developed a breast imaging reporting and data system (BI-RADS) lexicon for breast sonography to standardize the characterization of breast lesions (22). Several studies have reported that scoring findings from breast ultrasonography based on the criteria used for BI-RADS allowed highly accurate differentiation of benign structures from malignant breast tumor (23)(24)(25). The present study compared the accuracy of PDS and grayscale sonography standardized by BI-RADS for differentiating scar formation and IBTR after BCT.…”

Abstract. The diagnosis of ipsilateral breast tumor recurrence (IBTR) after breast-conserving therapy is of great interest to breast physicians. The present study compared the utility of grayscale sonography standardized by a breast imaging reporting and data system (BI-RADS) and power Doppler sonography for differentiating between benign scar formation and IBTR after breast-conserving therapy. Gray-scale sonography detected 83 solid breast lesions classified as BI-RADS categories 3-5 in 272 patients after breast-conserving therapy, and these lesions were entered into the study (53 lesions as category 3, probably benign; 30 lesions as categories 4-5, suspected malignancy). Power Doppler sonography revealed intratumoral flow in 19 of 83 solid breast lesions. BI-RADS category 3 was accepted as probably benign and BI-RADS categories 4-5 were considered as suspicious for breast tumor recurrence in the gray-scale ultrasound criteria. Positive and negative intratumoral flow were employed as suspicious for breast tumor recurrence and probably benign, respectively, in the power Doppler sonography criteria. Sensitivity was higher for power Doppler sonography (94.7±10.0%) than for gray-scale sonography (57.9±22.2%). Specificity was also higher for power Doppler sonography (98.4±3.0%) than for gray-scale sonography (70.3±0.6%). These results suggest that power Doppler sonography can complement gray-scale sonography standardized by BI-RADS in differentiating between IBTR and benign scar lesions. IntroductionIn the mid-1980s, the National Surgical Adjuvant Breast and Bowel Project (NSABP) B-06 trial demonstrated no difference in survival between mastectomy versus lumpectomy followed by radiation (1). Recently, breast-conserving therapy (BCT), defined as lumpectomy followed by whole-breast irradiation, has become the most common therapeutic option for breast cancer (2-4). Approximately 10-15% of patients undergoing BCT for operable breast cancer develop locoregional recurrence within 10 years (5-7). Patients with ipsilateral breast tumor recurrence (IBTR) without simultaneous distant metastases are considered as good candidates for salvage mastectomy (8,9) or repeat BCT (8,10). However, IBTR is considered to represent one predictor of systemic recurrence and breast cancer-related death after BCT (11). The diagnosis of IBTR after BCT is thus of great interest to breast physicians. BCT is less radical and has a more favorable psychological impact on patients, but frequently results in postoperative changes (12-18). Such changes may include both IBTR and benign situations such as scarring, reparative changes, accumulation of exudate or liquid, post-irradiation mastitis and fibrosis (12-18). The value of both mammography and ultrasonography after BCT is limited, as scars tend to be indistinguishable from IBTR (16,17). According to , ultrasonography was markedly more sensitive than mammography for detecting benign abnormalities after BCT (ultrasonography, 95.7%; mammography, 72.3%). However, ultrasound-guided biopsy is reportedly ...

“…Access to prior images reduces the rates of false positives and unnecessary follow-up imaging [49], and peer-review and peer-learning improve interpretation quality [50]. Of the RADS tools, diagnostic accuracy has been studied most using BI-RADS ® which has consistently been shown to improve accuracy and the quality of interpretations in breast imaging [49,[51][52][53][54][55][56].…”

Improving diagnosis in health care: perspectives from the American College of Radiology

Abstract:In September of 2014, the American College of Radiology joined a number of other organizations in sponsoring the 2015 National Academy of Medicine report, Improving Diagnosis In Health Care. Our presentation to the Academy emphasized that although diagnostic errors in imaging are commonly considered to result only from failures in disease detection or misinterpretation of a perceived abnormality, most errors in diagnosis result from failures in information gathering, aggregation, dissemination and ultimately integration of that information into our patients' clinical problems. Diagnostic errors can occur at any point on the continuum of imaging care from when imaging is first considered until results and recommendations are fully understood by our referring physicians and patients. We used the concept of the Imaging Value Chain and the ACR's Imaging 3.0 initiative to illustrate how better information gathering and integration at each step in imaging care can mitigate many of the causes of diagnostic errors. Radiologists are in a unique position to be the aggregators, brokers and disseminators of information critical to making an informed diagnosis, and if radiologists were empowered to use our expertise and informatics tools to manage the entire imaging chain, diagnostic errors would be reduced and patient outcomes improved. Heath care teams should take advantage of radiologists' ability to fully manage information related to medical imaging, and simultaneously, radiologists must be ready to meet these new challenges as health care evolves. The radiology community stands ready work with all stakeholders to design and implement solutions that minimize diagnostic errors.
