肝海绵状血管瘤的超低磁场MR诊断

ULTRA──LOW MAGNETIC FIELD MR DIAGNOSIS OF HEPER ANGIOCAVERNOMA

报道６例经ＣＴ、超声、血管造影证实的肝海绵状血管瘤的超低磁场ＭＲ资料，本组资料表明：肝海绵状血管瘤在高低磁场ＭＲ的影像不同，即超低磁场ＭＲＴ１ＷＩ、Ｔ２ＷＩ均为高信号，高磁场Ｔ１ＷＩ为低信号、Ｔ２ＷＩ为高信号，这在诊断方面有其独特的优点。

The ultra-low magnetic field MR images of six patients with heper angiocavernoma confirmed by CT echocardiography and angiography were reported.Those images made clear.The images of Heper angiocavernoma taken by high and ultrlow magnetic field MR is different T1wi of the high magnetic field is low signal and T1wi of the ultro-low magnetic field is high,T2wl of them is xame,it is a unique merit in the diagnosis.
