Sixteen patients (17 lower extremities) were prospectively examined with venography and limited-flip-angle, gradient-refocused magnetic resonance (MR) imaging for the presence or absence of deep venous thrombosis. Thrombosed vessels showed decreased-to-absent signal intensity, while patent vessels had high signal intensity. In 16 of 17 extremities, MR images allowed accurate detection and localization of the thrombi found with venography. In the remaining extremity, MR imaging allowed correct identification of thrombus in the iliac and femoral veins but incorrectly demonstrated clot in the calf and popliteal veins. MR imaging with limited-flip-angle, gradient-refocused pulse sequences appears to be a sensitive, noninvasive means of detecting deep venous thrombosis.
对16例患者（17条下肢）进行了前瞻性研究，采用静脉造影和有限翻转角、梯度重聚磁共振（MR）成像检查有无深静脉血栓形成。血栓形成的血管信号强度降低或消失，而通畅的血管信号强度高。在17条下肢中的16条中，MR图像能够准确检测和定位静脉造影发现的血栓。在其余的下肢中，MR成像能够正确识别髂静脉和股静脉中的血栓，但错误地显示小腿和腘静脉中有血栓。采用有限翻转角、梯度重聚脉冲序列的MR成像似乎是检测深静脉血栓形成的一种敏感、非侵入性方法。
