![]() Detection of mammographically occult architectural distortion on digital breast tomosynthesis screening: initial clinical experience. (2016) Radiographics : a review publication of the Radiological Society of North America, Inc. Tomosynthesis-detected Architectural Distortion: Management Algorithm with Radiologic-Pathologic Correlation. Durand MA, Wang S, Hooley RJ, Raghu M, Philpotts LE. Pathologic Outcomes of Architectural Distortion on Digital 2D Versus Tomosynthesis Mammography. On some charts depth contours are shown in solid lines the depth represented by each line is shown by numbers placed in breaks in. The types of lines used for various depths are shown in Section I of Chart No. These lines present a picture of the bottom. Comparison of digital mammography and digital breast tomosynthesis in the detection of architectural distortion. Soundings are supplemented by depth contours, lines connecting points of equal depth. Dibble EH, Lourenco AP, Baird GL, Ward RC, Maynard AS, Mainiero MB. Gaur S, Dialani V, Slanetz PJ, Eisenberg RL.

D’Orsi CJ, Sickles EA, Mendelson EB, Morris EA, et al. The BI-RADS Atlas suggests that an ultrasound finding of architectural distortion thought to be due to postsurgical scar may be categorized as probably benign ( BI-RADS 3), but there is sparse data supporting this approach 5. 3.Depths are considered safe if they are equal to or deeper than the. 2.The mariner sets the Safety Contour Depth equal to the Vessel Safety Draft, which is calculated as: Vessel Safety Draft Vessel Draft + Dynamic Squat + Safety Margin. In most cases, architectural distortion is a suspicious finding ( BI-RADS 4) 8, 9. Deep Contour: Indicates the limit of sea area where shallow water effects occur that can affect a vessel. 1.ECDIS allows the mariner to set the Safety Depth and the Safety Contour Depth independently. straightening or thickening of Cooper ligamentsĪrchitectural distortion can be reported as a standalone finding or be associated with (adjacent to) another finding, such as asymmetry, calcifications, or mass.blurring of normal tissue planes such as the fat-fibroglandular junction.focal retraction, distortion, or straightening at the edge of the parenchyma.radiating thin straight lines or spiculations.Mammography/US/MRIĪrchitectural distortion is characterized by a number of possible appearances 5: Targeted ultrasound should then be performed to confirm the finding, but MRI is an alternative if no ultrasound correlate is found 9. Compared to 2D mammography, digital breast tomosynthesis increases the sensitivity, confidence, and interobserver agreement in detection of architectural distortion 7-10. Tomosynthesis also helps localize the abnormality. Architectural distortion can be visually subtle.
