目标
我们的目标是使用优化的收缩期门控 3D 相差技术，评估 MRA 在检测疑似慢性肠系膜缺血患者的腹腔 (CA) 和肠系膜上 (SMA) 动脉狭窄方面的价值。
材料和方法
在一项针对不同临床指征接受传统腹部血管造影的 24 名患者的初步研究中，对 3D 相差 MRA 技术 (3D-PCA) 进行了评估和优化，以对 CA 和 SMA 进行成像。随后，进行了一项前瞻性研究，以评估收缩门控 3D-PCA 在评估 10 名患有慢性肠系膜缺血体征和症状的患者的肠系膜动脉中的价值。动脉内数字减影血管造影和手术结果作为参考标准。
结果
在最初的研究中，收缩门控似乎对于 3D-PCA 上的 SMA 成像至关重要。在 10 名疑似肠系膜缺血的患者中，收缩门控 3D-PCA 发现 4 名患者的两条肠系膜血管存在明显的近端疾病。这些患者的狭窄血管得到了成功的重建。
结论
心脏门控 MRA 可能成为选择疑似肠系膜缺血且可能从手术中受益的患者的有用工具。
OBJECTIVE
Our goal was to assess the value of MRA for detecting stenoses in the celiac (CA) and superior mesenteric (SMA) arteries in patients suspected of having chronic mesenteric ischemia, using an optimized systolically gated 3D phase contrast technique.
MATERIALS AND METHODS
In an initial study in 24 patients who underwent conventional angiography of the abdominal vessels for different clinical indications, a 3D phase contrast MRA technique (3D-PCA) was evaluated and optimized to image the CAs and SMAs. Subsequently, a prospective study was performed to assess the value of systolically gated 3D-PCA in evaluation of the mesenteric arteries in 10 patients with signs and symptoms of chronic mesenteric ischemia. Intraarterial digital subtraction angiography and surgical findings were used as the reference standard.
RESULTS
In the initial study, systolic gating appeared to be essential in imaging the SMA on 3D-PCA. In 10 patients suspected of mesenteric ischemia, systolically gated 3D-PCA identified significant proximal disease in the two mesenteric vessels in 4 patients. These patients underwent sucessful reconstruction of their stenotic vessels.
CONCLUSION
Cardiac-gated MRA may become a useful tool in selection of patients suspected of having mesenteric ischemia who may benefit from surgery.
