CAD for Breast Solution Shown to Increase Diagnostic Accuracy by 44 Percent

February 12, 2008 - A recent study found a significant increase in diagnostic accuracy when using Medipattern's B-CAD v2 on lesions less than 1 centimeter in size, based upon 100 confirmed biopsied cases, comparing the diagnostic accuracy of three reading scenarios: a single physician, double reading with two physicians and a single physician reading with B-CAD.

The study was conducted at the PLA301 Hospital in Beijing, PRC, revealed the accuracy of the single physician increased with B-CAD in all categories. The most striking result shows a 44 percent improvement in diagnostic accuracy for the single reader with B-CAD v2 on lesions less than 1 centimeter in size (n equals 9).

The physicians were not aware of the pathology outcomes when reading, and cases were separated into three size categories, malignant cancers greater than 2 centimeter, ranging from 1 to 2 centimeters and less than 1 centimeter. The cases were evaluated using the American College of radiology (ACR) Breast Imaging Reporting and Data System (BI-RADS) Lexicon. Doctors reading without B-CAD used the lexicon to characterize the lesions in the study and assess the diagnosis. B-CAD automatically finds the edge of the lesion and uses this information to characterize the lesion for the physician. B-CAD further consolidates the information into a detailed report documenting whether the lesion is probably benign or probably malignant.

"The Value of Computer-Aided Detection for Breast Ultra-Sonography (B-CAD) in the Diagnosis of Breast Cancer" by Dr. Li and Dr. Xu will be shared at the 18th annual conference of the National Consortium of Breast Centers (NCBC) which takes place March 1 to March 5, 2008 in Las Vegas. Each year participants are invited to submit an abstract to share research, programs, and results in order to facilitate communication among breast care centers and individual members.
