She’ll compare displays of masses, calcifications, and distortions in 2D mammography with displays in 3D tomosynthesis. This 75-minute Web-based training is enhanced with discussions of numerous clinical cases. Introduction Dr. Maria Bernathova Medical University of Vienna, Austria Introduction 04_Morphology-of-lesions_02-Intro-to-lecture_V02.mp4 Asymmetries and Spiculated Masses Asymmetries and Spiculated Masses Dr. Maria Bernathova Medical University of Vienna, Austria Asymmetries and Spiculated Masses 04_Morphology-of-lesions_03-Asymmetries-and-spiculated-masses_V02.mp4 The mimic effect of overlapping structures can be reduced. This results in fewer false-positive results. The mask effect of overlapping structures can be reduced. This results in fewer false-negative results. Low-contrast masses benefit the most from the ability to separate tissue in the z-direction. In-depth resolution isn’t important; only the in-plane resolution has a clinical impact. What is not a clinical benefit of high in-depth resolution? Knowledge Check Select the best answer. Knowledge Check Correct Incorrect The solution: In-depth resolution isn’t important; only the in-plane resolution has a clinical impact. Incorrect The solution: In-depth resolution isn’t important; only the in-plane resolution has a clinical impact. Correct The solution: In-depth resolution isn’t important; only the in-plane resolution has a clinical impact. Explanation of the Correct Answer Continue In-depth resolution is most important for overcoming the overlapping effect, which causes masking (FN) and mimicking (FP) of lesions, and the conspicuity of masses. In-plane resolution is important for detecting microcalcifications.

Please select a topic to access the related information. 1 1 1 2 2 2 3 3 3 4 4 4 Course Review Detection of Additional Lesions DBT compared to FFDM Detects more additional lesions in the same breast: multifocality/multicentricity. Distortions DBT has a unique capacity to detect architectural distortions, leading to more true-positive and false-positive findings. Distortions only visible on DBT (without ultrasound correlation) require tomo-guided biopsy and have a 19 % likelihood of malignancy. Microcalcification DBT compared to FFDM Iceberg phenomena: better detection, and characterization of lesions with associated microcalc. Better visualization of the 3D distribution of microcalc. Evaluation of microcalc clusters requires experience with DBT reading. In general, microcalc is better detected in FFDM. Asymmetries and Spiculated Masses DBT compared to FFDM Improves detection of masses and architectural distortions, resulting in higher sensitivity. Reduces mimic effect resulting in fewer false-positive asymmetries. Offers higher conspicuity for spiculated masses. Following the market introduction in 2009, several clinical studies on Digital Breast Tomosynthesis have proven the value of this technique for breast imaging.
