February 13, 2008 - A study has found that Medipattern's B-CAD 2, a computer-assisted detection program, increased the diagnostic accuracy up to 44 percent on lesions less than 1 cm in size, according to Medipattern Corp.
B-CAD v2 is only available outside the U.S.
The study was conducted at the PLA301 Hospital in Beijing, China and was 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 accuracy of the single physician increased with B-CAD in all categories. According to Medipattern, the most striking result showed a 44 percent improvement in diagnostic accuracy for the single reader with B-CAD v2 on lesions less than 1 cm in size.
The physicians were not aware of the pathology outcomes when reading. The cases were separated into three size categories, malignant cancers greater than 2 cm, ranging from 1 to 2 cm and less than 1 cm. 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.
