MR imaging of spinal cord and vertebral body infarction.
PURPOSE To study the usefulness of MR in the evaluation of spinal cord infarctions and associated findings. MATERIALS AND METHODS MR examinations of 12 patients (10 men and two women) were reviewed retrospectively. Onset of symptoms of spinal cord ischemia was abrupt in all patients; MR was performed 8 hr to 4 months after onset. Contrast-enhanced MR was performed in four of the patients. R...
متن کاملMR imaging characteristics of tuberculous spondylitis vs vertebral osteomyelitis.
Retrospective evaluation was made of four patients with tuberculous spondylitis who had been studied by MR with T1- and T2-weighted images in the sagittal plane and spin-density-weighted images in the axial plane. Evaluation was made of the distribution of abnormal signals within the body and posterior elements of the vertebrae, the intervertebral disk, and the associated paraspinal and epidura...
متن کاملSequential changes of traumatic vertebral compression fracture on MR imaging.
The purpose of this study was to evaluate the sequential signal intensity changes in post-traumatic vertebral compression fractures of varying ages. Sixty-six patients with 115 post-traumatic vertebral compression fractures underwent MR imaging. The ages of fractures at the time of MR images ranged from 1 day to 6 years. Sequential follow-up MR imagings were obtained in 4 patients for 2 years a...
متن کاملDiffusion weighted MR imaging in the differential diagnosis of haemangiomas and metastases of the liver
BACKGROUND The purpose of the study was to evaluate the value of diffusion-weighted imaging in the differential diagnosis of haemangiomas from metastases of the liver. PATIENTS AND METHODS.: We analyzed 69 lesions in 38 patients (33 haemangiomas; 36 metastases) in the retrospective study. Diffusion-weighted imaging was performed using a breath-hold single-shot echo-planar spin echo sequence wi...
متن کاملDiffusion-weighted MR imaging offers no advantage over routine noncontrast MR imaging in the detection of vertebral metastases.
BACKGROUND AND PURPOSE Diffusion-weighted MR imaging of the spine has been used to differentiate benign from pathologic vertebral body compression fractures. We sought to determine the utility of diffusion-weighted MR imaging in the detection of vertebral metastases and to compare it with conventional noncontrast T1- and T2-weighted MR imaging. METHODS Fifteen patients with metastases to the ...
