摘要
目的:利用团注追踪3D CE-MRA技术实现重症疑难患者的腹部及双下肢血管一次成像。方法:对6例疑有腹部、盆腔及双下肢血管疾病的体位不能合作的重症患者,实行团注追踪3D CE-MRA一次成像检查。使用Philips gyroscan intera 1.5T超导磁共振机,体部正交线圈,腿部专用支垫,结合bolustrack和mobitrack智能化追踪扫描技术,实现腹部至双下肢动脉血管的一次成像。结果:6例重症患者均能配合完成检查,成功实现腹部至双下肢动脉血管的一次成像,获得满意的成像效果。结论:选择患者可以配合的合适体位,调整好相对应的扫描技术参数,利用团注追踪3D CE-MRA技术可以实现重症患者的腹部至双下肢动脉血管的一次成像,克服了这类患者因体位不能配合检查而错失手术和治疗良机的难题。
Abstract
Objective: To image the arteries and veins of the abdomen and lower extremities in the crucial patients, using bolus tracking 3D CE-MRA technology. Material and Methods: With Philips gyroscan intera 1.5T superconducting MR machine, body coil and special leg rest, using bolustrack and mobitrack(intelligent tracking skill) scan technology, 4 crucial patients suspected of vascular disease, who can’t cooperate with doctors, were scanned. Results: All the 4 patients were able to accomplish the examination and the images of the vessels from the abdomen to lower extremities were of high quality with satisfied results. Conclusion: Suitable posture chosen, corresponding parameters well-modified and bolus-tracking 3D CE-MRA technology adopted, we can obtain high-quality images of vessels, even for the severely sick patients and thus we can provide necessary information in time before operation and therapy.
