title: [Significance of imaging techniques (roentgen, scintigraphy, MRI) in the diagnosis and therapy planning of Perthes disease].
abstract: The value of MRT, bone scintigraphy and conventional radiographs were studied for early stage diagnosis of Perthes' disease. Our experience in a series of 28 patients showed MRI to have a 100% sensitivity and specificity compared with bone scintigraphy (68.1% and 66.7%) and normal radiographs (58.3% and 100%). MRT often demonstrates changes while the conventional radiographs or bone scans appear normal. This might reflect the ability of MRT to detect the histopathologic changes before a measurable bone mineral change occurs.
