Forty-six primary total knee arthroplasties were performed using either an electromagnetic (EM) or infrared (IR) navigation system. In this IRB-approved study, patients were evaluated clinically and for accuracy using spiral computed tomographic imaging and 36-in standing radiographs. Although EM navigation was subject to metal interference, it was not as(More)
In 22 patients with a diverse range of thoracic abnormalities, T2-weighted magnetic resonance (MR) images of the chest were obtained with electrocardiograph (ECG)-triggered turbo spin-echo (TSE), ECG-triggered conventional spin-echo (CSE), and nontriggered TSE sequences, and the images were compared. A 5-point rating scale was used by three radiologists(More)
The purpose of this study was to use magnetic resonance imaging to evaluate various parameters of the patellar tendon during the first year after harvest for anterior cruciate ligament (ACL) reconstruction. Twelve consecutive patients were serially imaged on a 1.5 Tesla GE magnet (GE Medical Systems, Milwaukee, WI) with a dedicated knee coil at 3 weeks, 3(More)
PURPOSE To study the articular morphology (radius of curvature), (diameter, depth, circularity, and percent of circle) of the capitate, proximal lunate, and the lunate fossa of the distal radius using both magnetic resonance imaging (MRI) scans and plain radiographs. The correlation between plain radiographs and MRI scans for these measurements will also be(More)
PURPOSE The purposes of this study were as follows: (1) to locate the position of the distal wrist flexion crease with respect to the carpal bones, specifically the proximal pole of the capitate, and (2) to determine the cross-sectional area of the carpal canal proximal and distal to the wrist flexion crease to enable us to determine whether or not there is(More)
BACKGROUND Cored autologous graft from the distal ipsilateral femur has been used to fill osteochondral defects in the talus. There are no studies that compare the articular morphology of potential donor sites on the distal femur with recipient sites on the talus. METHODS Using coronal MRI of the talus and distal femur of five matched cadaver, computer(More)
Transitional cell carcinoma (TCC) of the bladder typically metastasizes to the pelvic lymph nodes and to visceral sites including the lungs, liver, and bones. Other sites include the brain, especially after systemic chemotherapy. To our knowledge, we report the first case of TCC metastatic to the soft tissue of the shoulder girdle and discuss common and(More)
Imaging evaluation is important in the follow-up of patients who have undergone surgical repair of the aorta. We present a case in which MR imaging demonstrated compression of the superior vena cava (SVC) as a late complication of ascending aortic aneurysm surgery. This complication led to thrombosis and clinical SVC syndrome.
