| Abstract: | Objective:To determine preliminary the values and limits of computed tomographic angiography (CTA)in assessment of arterial supplying to the femur head.Methods:Two thousand and one sets of femoral head thin slice CT axial images in arterial phase were retrospectively 3D reconstructed on AW 4.2 workstation.CTA was obtained by using the 4-detector row CT scanning after single-bolus injection of 95 mL contrast media at 4 mL/s from the peripheral vein.The supply arteries was observed.Results:The CTA sensitivity... |
