SENSE技术在磁共振腹部动态增强血管成像中的应用

目的：探讨磁共振敏感编码技术在腹部动态增强血管成像(DcE—MRA)中的应用优势。方法：将疑有腹部血管疾病的40例患者分为二组,实验组20例使用SENSE技术扫描;另外20例为对照组,直接行DCE—MRA扫描。结果：对照组20例中,13例因患者呼吸配合好,图像清晰,其中5例显示了动、静脉不同时相,8例由于扫描时间长,得到动、静脉均显影的图像。其余7例因屏气配合不好,图像出现伪影,为诊断带来了困难。实验组20例患者由于扫描时间明显缩短,均获得了清晰且不同时相的图像。结论：sENsE技术的使用大大地缩短了扫描时间,使腹部DCE—MRA可不受呼吸影响,并能获得不同时相血管强化图像,明显改善了DcE—MRA影像的质量,提高了诊断准确性。

Application of SENSE in abdominal dynamic contrast enhanced magnetic resonance angiography

Objective:To investigate the advantage of sensitivity encoding (SENSE) technique in abdominal dynamic contrast enhanced magnetic resonance angiography (DCE MRA).Methods:Forty patients with clinical suspected abdominal vascular diseases were divided into two groups.Experimental group was performed SENSE technique and the control group was directly carried out DCE MRA scanning.Results:In the control group,thirteen patients got clear images because of good holding of their breath, and 5 cases obtained images of arteries and veins respectively and 8 cases simultaneously.The other 7 cases got images with serious artifacts due to bad breath holding.In experimental groups,all 20 cases got clear images of arteries and veins due to shortening of scanning time.Conclusion:SENSE technique greatly shortens scanning time and obviously improvs DCE MRA images quality and can increase the diagnostic accuracy.
