PURPOSE To study the possible correlation between iodine uptake in contrast-enhanced digital mammography images and microvessel density (MVD) in breast lesions. METHODS 20 BIRADS 4-5 patients were included. Mask images were acquired with low-and high-energy spectra from a SenographeDS. Iodine-based contrast medium (CM) was mechanically injected and(More)
A system designed to assist visual impaired persons to travel in a city without external help using GPS navigation system has been developed. With the use of a BIuetooth hands-free, the user only has to give spoken commands to receive spoken directions to get to his/her destination. The directions received from the system will help him/her to walk parallel(More)
OBJECTIVE To correlate image parameters in contrast-enhanced digital mammography (CEDM) with blood and lymphatic microvessel density (MVD). METHODS 18 Breast Imaging-Reporting and Data System (BI-RADS)-4 to BI-RADS-5 patients were subjected to CEDM. Craniocaudal views were acquired, two views (low and high energy) before iodine contrast medium (CM)(More)
