Abstract:
Objective To investigate the MR postprocessing workstation on PC level.To discuss the hardware enviroment suitble for the lab MR postprocessing and the correspongding clinical diagnostic value. Methods MR diffuison-weighted imaging and routine MRI were performed in 6 normal adults.The ADC and AI parameter images were rebuilt by using Perfect-Tech (version 2.0) software on the market saled PC computer. Results The process and analysis could be performed sucessfully on the the market saled PC computer. On the ADCav images,the boundary between the grey matter(GM)and white matter(WM) was blurring and showed the similar intensity.The anistropy in white matter was averaged out on the ADCav images.The ADC value was (7.59?1.12)?10 -4 mm 2/s in WM and (10.50?4.34)?10 -4 mm 2/s in GM. On the AI images,there was sharp boundary between GM and WM,with hypointensity in GM and hyperintensity in WM. The anistropy contrast was enhanced on AI images. AI was 0.20?0.09 in WM and 0.09?0.07 in GM with statistically significant difference between them(t=4.13,P
