The Preliminary Study Of 64-Slices Helical CT Perfusion Imaging And Post-Processing Technique In Breast Disease

Part 1 A preliminary study of 64-slices helical CT perfusion imaging in breast diseaseObjective: To evaluate preliminarily 64-slices helical CT perfusion imaging in diagnosis of the breast disease.Materials and Methods: Thirty two patients with breast diseases suspected by clinical examination or mammography were scanned by 64-slices helical CT perfusion. They were classified into four groups according to the pathological results: normal breasts (according to the clinical and imaging diagnosis,n=31), carcinomas(n=12), fibroadenomas (n=5) and hyperplasia of breasts(n=11)."Body perfusion"method was used and the imaging data were processed using"Perfusion 3 body"software package. Their hemodynamic parameters including blood flow(BF), blood volume(BV), mean transit time(MTT), permeability surface (PS) were measured in region of interest and analyzed statistically.Results: The normal breasts,the breast carcinomas, the fibroadenomas and the hyperplasia of breasts showed low perfusion, high perfusion,higher perfusion and higher perfusion, respectively. There were statistically...
