ABSTRACT
This article discusses intravenous and intra-articular uses of contrast in cross-sectional imaging for the evaluation of musculoskeletal abnormalities. Emphasis will be placed upon the important traditional uses of contrast-enhanced computed tomography and the recent developments in contrast-enhanced magnetic resonance imaging.

This article discusses the unique contribution of MR imaging to the evaluation of selected pediatric disorders of the ankle and foot. MR imaging is helping to unravel the complex congenital malformation of talipes equinovarus. It is the study of choice for the examination of intraarticular abnormalities such as Trevor's disease. The MR imaging staging of osteochondritis dissecans and delineation of a tarsal coalition have shown great promise in guiding surgical management of these abnormalities.

The variety of imaging techniques available to the clinician facilitates the diagnosis of acute and chronic wrist disorders. In most cases, conventional radiographs provide sufficient information. Computed and trispiral tomography, arthrography, video-fluoroscopy, and magnetic resonance imaging are additional imaging techniques that are useful in making the correct diagnosis and deciding on a course of treatment.

Infrapopliteal balloon angioplasty was performed in 11 patients facing reconstructive surgery for limb salvage. Twelve separate sessions of angioplasty were performed, during which 15 of 16 diseased tibial runoff vessels were successfully dilated. Three complications occurred during percutaneous transluminal angioplasty (PTA). One was related to the concomitant use of a thrombolytic agent to open a femoropopliteal bypass graft and not related to the angioplasty itself. No limbs were lost as a result of complications. The procedure was a technical success in nine of 12 cases (75%) and an initial clinical success in eight of the nine that were technically successful (89%). Follow-up ranged from 1 to 22 months. Six of the nine cases (67%) remained clinically successful during this period. Preliminary results suggest that infrapopliteal PTA is a safe and effective alternative to surgical reconstruction in selected patients.
