Imaging Diagnostic Systems CT Laser Mammography (CTLM(R)) System Featured at the 94th Annual Radiological Society of North America (RSNA) ...( FORT LAUDERDALE Fla. Dec. 1 /- Imagin...)

FORT LAUDERDALE, Fla., Dec. 1 /PRNewswire-FirstCall/ -- Imaging Diagnostic Systems, Inc., (OTC Bulletin Board: IMDS), a pioneer in laser optical breast imaging, announced today that a recent study on CTLM is one of the featured scientific abstracts at RSNA 2008, November 30th - December 5th. Dr. Jin Qi, a radiologist at the Tianjin Medical University Cancer Institute and Hospital, Tianjin, China, was selected for her paper, "CTLM as an Adjunct to Mammography in the Diagnosis of Patients with Dense Breasts." Dr. Qi is attending RSNA with IDSI and will be present at the company's exhibit.

Her study, which evaluated CTLM as an adjunct to mammography in women with heterogeneously or extremely dense breast tissue, found that CTLM could successfully distinguish malignant from benign lesions in dense breasts. The system's imaging capabilities were not affected by tissue density in breasts and could provide information about angiogenesis in malignant and benign breast lesions.

Women who were scheduled for biopsy were first evaluated with mammography to classify breast density and then examined by the CTLM system. The CTLM examination was performed subsequently with mammography. The findings were then compared to mammography alone, the CTLM system alone, and CTLM and mammography adjunctively. Sensitivity, specificity, and positive predictive values were calculated by using standard methods. Among the extremely dense breast patient population, the sensitivity of mammography alone was 34.40%. CTLM alone resulted in a sensitivity of 74.40%, and mammography plus CTLM produced a sensitivity of 81.57%. The specificity of mammography alone was 90.48%; CTLM alone, 71.00%; and mammography plus CTLM was 72.22%.
