Abstract Forty-six patients with suspected avascular necrosis of the femoral head were examined by T2- and T1-weighted sequences before and after intravenous infusion of Gd-DTPA. Both sides were involved in 12 cases. The classification was done according to Ficat [1]. In early stages and in postoperative studies a correlation of signal intensity increase after infusion of Gd-DTPA and clinical symptoms was found. Contrast enhancement of the plain low signal intensity area or of the implanted graft on T1-weighted images was assumed vascularized or vital components in seven cases of Ficat I and in 13 postoperative studies. Contrawise, in seven patients with severe postoperative symptoms we found no contrast enhancement indicating avascular regions.
