Concordance of Breast Imaging Reporting and Data System with Routine Interpretation of Digital Mammography

Abstract

The American College of Radiology’s (ACR) Breast Imaging Reporting and Data System (BI-RADS) provide a lexicon that give a standard way of reporting mammogram that help ensure better follow up of suspicious findings.The study conduct to assess the concordance of final findings of mammograms reported using BI-RADS lexicons and the final impression of radiologist those using routine interpretation of mammogram. The data descriptively analyzed and Kappa value was determined to measure the concordance. The result appeared as the concordance of the breast composition was (k = 0.5) that point Moderate agreement. According to mass, the presence of the mass was (k = 0.83) that was a Very Good agreement, the shape of the mass was (k = 0.53) that a Moderate agreement, the margin of the mass was (k = 0.475) that point Moderate agreement, the density of the mass was (k = 0.74) that point a good agreement, in addition the associate calcifications was (k = 1) that point a total agreement. According to calcification the Kappa value was for presence (k = 0.87) that point to Very Good agreement, the morphology of the calcifications was (k = 0.85) that point to Very Good agreement and distribution was (k = 1) that point Very Good agreement. In addition, the architectural distortion was (k = 0.85) that point to Very Good agreement, and A symmetry was (k =0.138) it was poor agreement. The intramammary lymph node was (k = 0.65) that point a good agreement and the overall agreement and concordance to the final finding was (k = 0.58) that point to a moderate agreement. As the conclusion the study revealed that there is a wide variation in wording of the mammography report between the radiologists. Therefore, it is very important to follow the BIRAD lexicon in order to avoid any misunderstanding or confusion.
