非对比增强（CE）磁共振血管造影（MRA）技术是相当感兴趣的诊断血管疾病的上肢，由于重复检查的可能性，测量体积的充分覆盖，因为可能的副作用，管理碘或钆基造影剂和辐射暴露可以避免。本研究的目的是探讨优化的心电图（ECG）触发的笛卡尔静止间隔选择性（QISS）技术用于手部动脉MRA的可行性。使用优化的QISS-MRA脉冲序列在1.5特斯拉下检查20名健康志愿者（HV）的双手。将腕、手部动脉树分为36段。测量所有动脉段的横截面积（CSA）。对于脉冲序列的技术评价，计算信噪比（SNR）和对比度噪声比（CNR），并对6种成像伪影进行分级。两名经验丰富的观察员使用顺序评分系统评估每个动脉节段的图像质量。确定观察者间的一致性。尺动脉和桡动脉的平均CSA为7.3 mm 2，4条指总动脉为3.2 mm 2，5条固有指动脉为1.5 mm 2。第三固有总动脉的SNR和CNR中位数分别为45.9和20.3。所有动脉段均未被静脉强化污染。在所有1440个动脉节段中，双手动脉节段的图像质量被认为是诊断性的占87.2%。使用五级评分系统确定双手动脉节段图像质量的观察者间一致性为0.67。优化的QISS-MRA作为第一种MRA技术允许对掌浅弓（SPA）和掌深弓（DPA）变体进行分类。与先前使用CE计算机断层扫描血管造影和使用固定尸体手的研究相比，使用QISS-MRA可以对5种新的SPA和6种新的DPA变体进行分类。通过使用这种优化的2D笛卡尔QISS-MRA协议，手腕和手部动脉的无造影剂血管造影提供了高平面内空间分辨率和良好的小指动脉可视化。
Non-contrast-enhanced (CE) magnetic resonance angiography (MRA) techniques are of considerable interest for diagnosing vascular diseases in the upper extremities owing to the possibility of repeated examinations, sufficient coverage of the measurement volume, and because possible side effects of administering iodine- or gadolinium-based contrast agents and radiation exposure can be avoided. The aim of this study was to investigate the feasibility of an optimized electrocardiogram (ECG) triggered Cartesian quiescent interval slice selective (QISS) technique for MRA of hand arteries. Both hands of 20 healthy volunteers (HVs) were examined using an optimized QISS-MRA pulse sequence at 1.5 Tesla. The wrist and hand arterial trees were divided into 36 segments. Cross-sectional areas (CSA) of all arterial segments were measured. For the technical evaluation of the pulse sequence, the signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) were computed and six imaging artifacts were graded. Two experienced observers used an ordinal scoring system to assess the image quality of each arterial segment. Interobserver agreement was determined. The median CSA was 7.3 mm2 in the ulnar and radial artery, 3.2 mm2 in the four common digital arteries, and 1.5 mm2 in five proper digital arteries. The median SNR and CNR of the third common proper arteries were 45.9 and 20.3, respectively. None of the arterial segments were contaminated by venous enhancement. The image quality of arterial segments for both hands was considered as diagnostic in 87.2% of all 1440 segments. An interobserver agreement of 0.67 for both hands was determined for image quality of arterial segments using a five-grade scoring system. Optimized QISS-MRA allows as the first MRA technique the classification of superficial palmar arch (SPA) and deep palmar arch (DPA) variants. 5 new SPA and 6 new DPA variants could be classified using QISS-MRA in comparison with previous studies using CE computed tomography angiography and using fixed cadaver hands. By using this optimized 2D Cartesian QISS-MRA protocol, contrast agent-free angiography of the wrist and hand arteries provided a high in-plane spatial resolution and an excellent visualization of small digital arteries.
