This study aims at finding optimal threshold in diffusion tensor tractography (DTT) of pelvic floor muscles. Twenty healthy adults (ten males and ten females) were included in this study. Conventional MRI sequences(T1WI, FSE-T2WI) and diffusion Tensor Imaging (DTI) were acquired in GE Signa HDxt 3.0T MRI. Then the DTI were post-processed in ADW4.5 workstation. Levator ani muscle, coccygeus and obturtor...
Objective: To investigate the multi-detector computed tomography (MDCT) manifestations of the normal sigmoid mesocolon. Methods: Fifty cases were studied to evaluate the 64-detector computed tomography appearances of the normal sigmoid mesocolon. Results: (1) The inferior mesenteric artery (IMA) and inferior mesenteric vein (IMV) were identified on axial, coronal and sagital MDCT images in 50 cases...
Purpose: Discussing the effect of magnetic resonance diffusion weighted imaging with background signal suppression that used to evaluate the efficacy of angiogenesis inhibitor endostatin that applied in the treatment of rabbit liver VX2 hepatic transplantation model. Method: Tumor-bearing rabbits were randomly divided into two groups, each group with eight rabbits, saline (10ml / d) was injected into...
Comparing the imaging features on the ordinary fa-value and high-b-value DWIBS with that on the enhanced imaging, to explore the value of 3.0T MR high-b-value diffusion weighted imaging with background suppression (DWIBS) in detecting the cerebral metastases. 41 patients with cerebral metastases confirmed by clinically and pathologically were collected. All the patients underwent conventional MRI...
Objective: To evaluate the multi-slice computed tomography (MSCT) manifestations of the normal small bowel mesentery. Methods: Sixty cases were study to assess the 64-slice CT manifestations of the normal small bowel mesentery. Results: (1) The superior mesenteric artery/ vein were identified on axial, sagittal and coronal CT images in 60 cases. The diameter of the jejunal mesenteric vein (which had...
To investigate the CT findings of gastrocolic ligament involved by acute pancreatitis(AP) and study the correlation between CT findings and CT Severity Index (CTSI) of AP. Methods: Seventy-nine patients with AP were retrospectively reviewed. Balthazar's CT classification of all the patients' was C grade or more. Emphasis was placed on the following findings: the CTSI, the thickness and density of...
Objective: This study aims to construct the imaging network teaching system based on picture archiving and communication system (PACS). Material and methods: Taking image storage and communication system from GE medical system as the basic platform, this study attempts to design the teaching service unit in accordance with teaching requirements of the university. In addition, with the basis of multimedia...
Objective To investigate the feasibility of using PWI analysis software in assessment of carbogen breathing BOLD-fMRI in normal prostate. Materials and Methods BOLD-fMRI was performed using a 1.5 Tesla superconducting magnetic scanner (Siemens) equipped with a pelvic phased-array multi-coil in 15 healthy volunteers. BOLD (T2*-weighted EPI sequence, 13 slices, 3mm thickness) were acquired during 5×2minute...
