FAQ
Our Frequently Asked Questions (FAQ) are that nifty sections of our projects where we will find answers to recurring the project questions. For our BreastScreening (FAQ), MIDA (FAQ) and MIMBCD-UI (FAQ) projects, they guide us to perform common actions, such as typical configurations or fixing some issues. Please, follow the respective FAQ for each project, as it may have different Questions/Answers.
The purpose of this section is to provide answers regarding several aspects of the BreastScreening project. A project that is highly contributed by both MIDA and MIMBCD-UI projects. The project is part of the work done between SIPg, an ISR-Lisboa group, and University of Adelaide. ISR-Lisboa is one of the Associate Laboratories from IST at ULisboa.
Below, we will find answers to all of your Medical Imaging (MI) questions. Bookmark this page and check back often, as it is updated with new questions.
In this section, we present a more detailed Frequently Asked Questions (FAQ) regarding the important context of the Breast Cancer across our projects. Understanding Breast Cancer variables is important to our project since the answers to it will cover the respective domain scope of the project.
A startling fact is that 1 in 8 women will be diagnosed with breast cancer in their lifetime.
How to Classify Examinations as True-Positive (TP), True-Negative (TN), False-Positive (FP), and False-Negative (FN)?
Source: ACR BI-RADS® ATLAS — Follow-up and Outcome Monitoring - Frequently Asked Questions Concerning Breast Imaging Audits
A woman has a mammography screening examination at a facility in which the examination is interpreted before the woman leaves the premises so that additional imaging can be performed immediately if needed. A noncalcified asymmetry is seen in one breast, only on the craniocaudal view. The interpreting radiologist obtains a second craniocaudal view to clarifying the significance of this asymmetry. The examination is then interpreted as negative because the asymmetry (judged to represent a summation artifact) is not visible on the repeat craniocaudal view.
This single examination in effect represents a positive screening examination (BI-RADS® category 0), for which the woman was recalled for additional diagnostic imaging that resulted in a negative 2013 64 American College of Radiology FOLLOW-UP AND OUTCOME MONITORING (BI-RADS® category 1) assessment. Thus, the screening component of this examination should be classified as false-positive (FP), and the diagnostic component of the examination should be classified as true-negative (TN). Note that whenever a screening examination is interpreted before a woman leaves the premises, and the examination is converted to a diagnostic examination to clarify a sonographic finding identified on standard screening views (by the recording of additional images), this single examination should be considered to have a positive screening interpretation (BI-RADS® category 0) and also a positive or negative diagnostic interpretation depending on the final assessment that is rendered. Also note if the interpreting physician in the provided scenario had determined at repeat scanning that the initially depicted finding was an artifact without documenting this by recording one or more additional images, the completed screening examination would have contained only standard images, been assessed as negative (BI-RADS® category 1), and therefore been audited as true-negative (TN). However, also note that the approach of not recording additional images upon rescanning may subject the interpreting physician to malpractice exposure if breast cancer subsequently is diagnosed at the site of the depicted finding, although this exposure might be somewhat mitigated by adding a sentence to the screening report indicating that the depicted finding is considered to be an artifact because it could not be reproduced at subsequent rescanning (no additional images recorded).
