Detection of Architectural Distortion in Prior Mammograms via Analysis of Oriented Patterns
Published on: August 30, 2013
Abstract:
Xeromammographic false negatives were analyzed to ascertain the cause of the errors and determine what corrective measures could be taken. Of 52 cancers miscalled, 52% were not visualized and 48% were categorized as misinterpretations. The causes of these errors are discussed. The error rate in all but 8% of the former group appears to be irreducible, yet errors discussed in the latter group are thought to be correctable in a high percentage of cases. Recommendations to reduce the number of false negatives in this group are presented.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
