Hepatic injury from blunt trauma in children: follow-up evaluation with CT.
Because CT is now used to assess the extent of abdominal injury after blunt trauma, children with hepatic injury often can be treated nonsurgically. We used a CT grading system to evaluate the frequency of complications and the time course of healing in children with hepatic injury from blunt abdominal trauma. ⋯ CT grading of acute hepatic injuries is useful for estimating the time course of healing. Although mild and moderate hepatic injuries heal relatively quickly, severe hepatic injuries take months to resolve. Follow-up CT scans to verify complete hepatic healing should be obtained 3 months after mild injuries, 3-6 months after moderate injuries, and 9 months after severe injuries.

Partial anomalous pulmonary venous drainage of the left upper lobe vs duplication of the superior vena cava: distinction based on CT findings.
Partial anomalous pulmonary venous drainage of the left upper lobe and duplication of the superior vena cava have similar appearances on CT scans. The purpose of this study was to review their appearances and provide guidelines for differentiating between them. ⋯ Careful analysis of the CT scans with particular attention to these two features allows differentiation between partial anomalous pulmonary venous drainage of the left upper lobe and duplication of the superior vena cava.

Comparative StudyRelapsing-remitting multiple sclerosis: sequential enhanced MR imaging vs clinical findings in determining disease activity.
Sequential MR imaging frequently shows disease activity (clinically silent new brain lesions) in subgroups of patients with multiple sclerosis and therefore is valuable in monitoring the effects of treatment. Monitoring of disease activity in patients being treated for relapsing-remitting multiple sclerosis will increase in importance as new and safe therapies are developed. We studied sequential enhanced MR images of patients with early relapsing-remitting multiple sclerosis to define the MR features that indicate disease activity in this subgroup of patients and to compare MR imaging and clinical findings for this purpose. ⋯ Our results suggest that contrast-enhanced MR imaging is more sensitive than clinical monitoring for detecting new disease activity in patients with relapsing-remitting multiple sclerosis and that MR imaging might be useful in the evaluation of therapeutic regimens.
