Among all noninvasive techniques, high-resolution ultrasonography used alone has rarely been used for the diagnosis of thrombosis in the calf. Nineteen patients with suspected AVT were examined with ultrasonography and phlebography during 4 months. For each patient, a sonogram and a phlebogram were taken within less than 24 hours and interpreted(More)

In the spin echo mode, sequences with long TR and long TE provide great contrast, while, conversely, sequences with short TR and TE produce images with a greater anatomical fidelity. This dual performance, a notion that had never been expressed as explicitly in imaging, has led to(More)
