OBJECTIVE The purpose of this study was to determine if there are magnetic resonance (MR) characteristics of the medial plica that correlate with the likelihood of plica resection. METHODS Sixty-six knee MR examinations from patients who underwent subsequent knee arthroscopy were evaluated retrospectively for the presence of a medial plica. The plicae(More)
The results of evaluation of the hila and mediastinum with 67Ga scans are contradictory, as are the recommendations by different investigators on the use of 67Ga scintigraphy in the clinical evaluation of patients with primary lung carcinoma. Nevertheless, the economy and logistic simplicity of evaluating local and distant metastases with a single imaging(More)
UNLABELLED Achieving union between host bone and massive structural allografts can be difficult. Donor and recipient human leukocyte antigen (HLA) mismatches and recipient antibody response to donor HLA antigens might affect union. In a prospective multiinstitutional study, we enrolled a consecutive series of patients receiving cortex-replacing, massive(More)
Osteochondral lesions are relatively common and usually occur as a result of trauma. They often are unrecognized acutely and lead to osteochondral defects and eventually osteoarthritis. Detection of these lesions has been aided by bone scan, CT, and MR imaging. Acute osteochondral fragments can be replaced and internally fixed. Chronic osteochondral defects(More)
OBJECTIVE The purpose of this report is to describe the imaging findings of nontraumatic avulsions of the pelvis. CONCLUSION A diagnosis of avulsion fracture of the pelvis in an adult without appropriate history of substantial trauma must raise the suspicion of an underlying malignancy. If a patient has not been diagnosed as having a primary neoplasm,(More)
Conventional MR imaging evaluation of the knee focuses mainly on the effects of acute trauma and degenerative conditions. Numerous other conditions that affect the knee may mimic clinical characteristics of common traumatic and degenerative disorders. Synovial and marrow abnormalities are frequently encountered and often unsuspected on routine MR imaging(More)
Because of the high local recurrence rate associated with surgical resection alone, patients with diffuse intraarticular pigmented villonodular synovitis were treated with surgical resection followed by colloidal chromic P32 synoviorthesis. The medical records of nine consecutive patients treated in this manner were reviewed retrospectively to determine the(More)
We report the imaging characteristics of osteochondritis dissecans of the tarsal navicular bone in four cases and review the current literature. Its radiological findings are similar to osteochondritis dissecans found in other sites: focal lucency that disrupts the sharp cortical line, the presence of sclerosis, and cortical depression.
