Patients with antiphospholipid antibodies: CT and MR findings of the brain.
The purpose of this study was to determine the spectrum of neuroradiologic findings in patients with antiphospholipid antibodies (APA) and to compare findings in systemic lupus erythematosus (SLE) and non-SLE patients. ⋯ Infarcts of various sizes and hyperintense white matter foci are the most common abnormalities seen on CT and MR imaging in patients with APA. We found no significant differences in frequencies of abnormalities seen between non-SLE and SLE patients.

Detection of nerve rootlet avulsion on CT myelography in patients with birth palsy and brachial plexus injury after trauma.
Recent advances in neurosurgical treatment of traumatic and birth-related brachial plexus injuries require differentiation of preganglionic nerve rootlet avulsion from postganglionic lesions. The purpose of this study was to evaluate the efficacy of thin-section high-resolution CT myelography for revealing cervicothoracic nerve rootlet avulsion in patients with brachial plexus injuries before surgery. ⋯ High-resolution CT myelography with thin contiguous axial section is sensitive for revealing complete nerve rootlet avulsion in patients with brachial plexus birth palsies and brachial plexus injuries after trauma. Preoperative CT myelography in these patients allows a more complete injury evaluation for accurate prognosis and surgical planning.

The purpose of this study was to assess the additional yield of a repeat skeletal survey in identifying and dating skeletal injury for cases in which child abuse was strongly suspected. ⋯ When child abuse is strongly suspected on the basis of the findings on the initial skeletal survey, other imaging studies, history, or physical examination, a follow-up skeletal survey is recommended to provide a through and accurate assessment of osseous injuries.

The purpose of this study was to evaluate thin-section helical CT for the frequency of visualization of the peripancreatic veins, the venous anatomy at the head of the pancreas, and variations of the venous anatomy. ⋯ Thin-section helical CT scans provide good visualization of the peripancreatic veins.
