Volumetric growth assessment of pulmonary lesions is crucial to both lung cancer screening and oncological therapy monitoring. While several methods for small pulmonary nodules have previously been presented, the segmentation of larger tumors that appear frequently in oncological patients and are more likely to be complexly interconnected with lung(More)
Objectives : To evaluate diffusion-weighted imaging (DWI) with low b factors of the peripheral zone (PZ) of patients with prostatic cancer. Materials and methods : An EPI diffusion MR sequence (TE = 75 ms, TR = 4000 ms, slice thickness = 4 mm), with low diffusion factors incremented by 10 s/mm 2 , has been developed on a 1.5 T magnet. Axial T2-weighted(More)
The fusion of computed tomography (CT) and positron emission tomography (PET) may improve diagnostic accuracy, but is limited by different breathing protocols. This study aimed at quantifying respiration-induced alignment errors. PET-CT was acquired in 24 patients. Contrast-enhanced whole-body CT was obtained in a single breath hold in the expiratory state(More)
