[Femur head necrosis. Diagnosis and morphologic analysis using roentgen, scintigraphy, computerized tomography and magnetic resonance tomography].
35 patients with a total number of 53 AVN were examined with conventional radiographs (n = 53), radionuclide scans (n = 37), CT (n = 19) and MRI (n = 53). Findings were classified according to FICAT (stage 0-IV). With a sensitivity of 96.2% and a specificity of 98.1% MRI proved to be the most accurate imaging modality especially in early stages. CT proved to be a reliable technique, too, although accuracy was less compared with MRI. Radionuclide scanning was of minor value with a sensitivity of 62.1% and a specificity of 59.5%. Typical findings with plain radiographs, radionuclide scans, CT and MRI in different stages of AVN are described.
