Femoral Head Osteonecrosis: Detection and Grading by Using a Rapid MR Imaging Protocol

Abstract

There was excellent agreement between the full and screening MR examinations for both detection of and determining the extent of osteonecrosis. The time and potential cost reduction achieved with a limited examination may allow introduction of MR imaging earlier in the diagnosis of femoral head osteonecrosis, as well as its more widespread use in patient care.
