Abstract

We compared two MR angiography (MRA) techniques, time-of-flight (TOF) and phase-contrast (PC), with digital substraction angiography (DSA), in relation to operative findings in 40 patients with cerebrovascular disease. The investigations were performed using a 1.5 T whole-body system. 2D- and 3D-TOF and 2D- and 3D PC sequences were used in sagittal and axial planes. Velocity-encoding of the PC sequence varied between 5 and 100 cm/ s, depending on the blood flow velocity. The 3D data-sets were analysed using a maximum intensity projection program. The sensitivity of TOF and PC is comparable with that of DSA in the diagnosis of venous thrombosis. MRA may be superior to DSA in patients with giant aneurysms.
