使用双侧接收线圈对周围动脉疾病 (PAD) 患者的股动脉进行成像。构建并评估了用于 3T 股动脉双侧 MRI 的八通道表面线圈阵列。双侧阵列能够对从深部到腘窝的 25 厘米股浅动脉 (SFA) 段进行成像。与其他三种市售线圈（4 通道躯干、正交头部、全身）相比，该阵列改善了外围的信噪比 (SNR)，并提高了体模中部的类似信噪比。体内 SFA 的多对比双边图像具有 1 毫米面内分辨率，可以直接将索引 SFA 中的病变与对侧血管中的相应解剖部位进行比较，而无需重新定位患者或线圈。在临床上可接受的约 45 分钟检查时间内获得一组双边飞行时间、T1 加权、T2 加权和质子密度加权图像。开发的双侧线圈非常适合监测 SFA 动脉粥样硬化病变的尺寸变化。
To image the femoral arteries in peripheral arterial disease (PAD) patients using a bilateral receive coil. An eight-channel surface coil array for bilateral MRI of the femoral arteries at 3T was constructed and evaluated. The bilateral array enabled imaging of a 25-cm segment of the superficial femoral arteries (SFA) from the profunda to the popliteal. The array provided improved the signal-to-noise ratio (SNR) at the periphery and similar SNR in the middle of a phantom compared to three other commercially available coils (4-channel torso, quadrature head, whole body). Multicontrast bilateral images of the in vivo SFA with 1 mm inplane resolution made it possible to directly compare lesions in the index SFA to the corresponding anatomical site in the contralateral vessel without repositioning the patient or coil. A set of bilateral time-of-flight, T1-weighted, T2-weighted, and proton density-weighted images was acquired in a clinically acceptable exam time of ≈45 minutes. The developed bilateral coil is well suited for monitoring dimensional changes in atherosclerotic lesions of the SFA.
