Magnetic resonance (MR) imaging was performed on six patients with thrombosis involving the transverse/sigmoid sinus and jugular bulb/vein. Venographic confirmation was obtained in five cases. Thrombi were characterized by increased intraluminal signal on all planes of section and pulse sequences. The change in signal intensity from first to second echo for thrombi was qualitatively less than that found with slow flow. Partial thrombosis in one case was seen as a ring pattern of central intermediate intensity corresponding to the thrombus, surrounded by a peripheral ring of signal void related to flowing blood. The MR findings closely correlated with venography in predicting thrombosis. Evidence of thrombi was not available from CT. Magnetic resonance is well suited for the diagnosis of occlusive disease of the dural venous sinus and jugular bulb.
对6例累及横窦/乙状窦及颈静脉球/颈静脉的血栓形成患者进行了磁共振（MR）成像检查。5例经静脉造影证实。血栓在所有层面的切片和脉冲序列上均表现为管腔内信号增强。血栓从第一次回波到第二次回波的信号强度变化在定性上小于慢血流所见。1例部分血栓形成表现为中央中等强度的环形，对应血栓，周围是与流动血液相关的信号缺失外周环。MR表现与静脉造影在预测血栓形成方面密切相关。CT未发现血栓证据。磁共振非常适合诊断硬脑膜静脉窦和颈静脉球的闭塞性疾病。
