Every year, 2.5 million women have screening mammograms in the United Kingdom. Around 8 per 1,000 women screened are diagnosed with a breast cancer and 3 per 1,000 women will present with an interval breast cancer following a negative screening mammogram and before their next mammogram.Robust quality standards have to be adhered to at every stage in the screening pathway in order to maintain the fine balance between detecting cancers early and avoiding unnecessary false-positive results. As part of this process, there is a mandatory requirement for screening units to review all breast cancers. We present a pictorial illustration of the lessons learnt from such a review in this essay. The cases described here are from one large breast screening unit in the North of England. In this unit, 30,000 to 40,000 women have a screening mammogram each year and these are all double read by human readers. All cases requiring recall and those where there is a disagreement between the first and second human reader go through a consensus/arbitration process involving a minimum of two human readers. Interval cancers are identified through a consistent process outlined by the screening program and are then subjected to a review by a minimum of two reviewers. In this process, the reviewers have access to the false-negative mammograms along with all priors that were available at the time of initial read. The reviewers make a decision on whether the initial mammogram is normal or abnormal without seeing the diagnostic mammogram with the interval cancer. They also categorize the density of the breast and describe the mammographic abnormality if there is any on a standardized interval cancer data collection form. Finally, they categorize the interval cancer into one of three types—“satisfactory,” “satisfactory with learning points,” or “unsatisfactory.”","PeriodicalId":51597,"journal":{"name":"Indian Journal of Radiology and Imaging","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2024-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140235123","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Contrast-enhanced imaging techniques are necessary to evaluate vascularity due to the limited sensitivity of conventional color Doppler techniques, in which motion artifacts are eliminated using wall filters. However, in this process, low-flow signals from small vessels also get removed unintentionally. Advancements in technology have revolutionized the way ultrasound images are generated, resulting in tremendous improvements in Doppler imaging techniques. The new, ultrasound-based noncontrast microvascular imaging techniques overcome the limitations of conventional Doppler, and are highly sensitive for detecting microvessels and low flow. The resultant high Doppler sensitivity leads to detection of vascularity in more breast lesions. It is important for radiologists to understand the imaging principles and the clinical implications of the new techniques, to optimally utilize them and aid correct diagnosis. Angio-PLUS is one such recent advancement, which uses unfocused or plane waves and three-dimensional wall filtering to analyze tissue motion in time, space, and amplitude domains that effectively distinguish between blood flow and tissue. The information is beneficial for assessing the lesion vascularity without using contrast. This article aims to explain the Doppler imaging techniques, their clinical applications, scanning methods, and review the common Doppler-based diagnostic criteria used in the evaluation of breast lesions.","PeriodicalId":51597,"journal":{"name":"Indian Journal of Radiology and Imaging","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2024-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140234614","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two-dimensional ultrasonography (USG) based “International Ovarian Tumuor Analysis Simple Rules (IOTA-SR)” are used primarily in clinical practice. Three-dimensional (3D) USG is an emerging modality. The authors conducted this study to compare the performance of 3D USG with IOTA-SR for preoperative differentiation of benign and malignant adnexal masses.\u0000 Methods This prospective observational study recruited 84 patients with adnexal masses undergoing surgical management. IOTA-SR and 3D USG with power Doppler examination were applied to characterize the masses and correlated with histopathology. Logistic regression analysis defined individual 2D and 3D USG parameters' significance in predicting malignancy. The receiver operating characteristic (ROC) curve was plotted for significant variables, and area under the curves (AUCs) with cutoff values were calculated using the Youden index.\u0000 Results Out of the 84 adnexal masses, 41 were benign and 43 were malignant. IOTA-SR were conclusive in 88.1% (74/84) cases, with a sensitivity of 83.78% (95% confidence interval [CI]: 67.99–93.81%) and specificity of 89.19% (95% CI: 74.58–96.97%). The sensitivity and specificity of 3D USG with power Doppler were 84% and 88%, respectively, with an AUC of 0.96 (95% CI: 0.92–0.99). Ten cases were inconclusive by the IOTA-SR, and 3D USG could further correctly differentiate four of these cases.\u0000 Conclusions The diagnostic performance of both techniques is comparable. With good diagnostic performance and easy applicability, IOTA-SR remain the standard of care. 3D USG, although a more objective assessment, requires further validation and standardization.","PeriodicalId":51597,"journal":{"name":"Indian Journal of Radiology and Imaging","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2024-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140235416","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
