SPECT in Diagnosis of Legg-Calve-Perthes Disease (Comparison with Planar and Pin-hole Scintigraphy)

In diagnosis of Legg-Calve-Perthes (LCP) disease clinical examination, X-ray, scintigraphic methods and recently MRI are used. The pin-hole scitigraphy and MRI are found the most sensitive in detection of adult aseptic femoral head necrosis. Our intention was to estimate sensitivity of SPECT in comparison with planar and pin-hole hip joint scinitgraphy. We examined 35 patients using planar and pin-hole scintigraphy and SPECT. The patients were distributed into 2 groups: those who had only positive clinical signs of LCP disease and those who had both clinical signs and positive X-ray findings. Our result showed that SPECT is the most sensitive among scintigraphic methods (100%). Pin-hole scintigram was also highly sensitive (91%), whereas planar scintigraphy remained the least sensitive. In our opinion it is reasonable to perform pin- hole scintigraphy when LCP disease is suspected. In case of negative result, it is useful to perform SPECT which is the most sensitive scintigraphic method for detection of LCP disease. It allows not only photon deficient area detection, but also a better insight into growth plates which is very important for therapy and prognosis of the disease. Although our group of patients was rather small we consider that high sensitivity of SPECT we reached in our study be near to MRI sensitivity.
