We have used T1 MR images to map the distribution of water contributing to the edema which follows femoropopliteal bypass surgery. Spin-echo images and true parametric T1 images were made at the same time. The spin-echo images were used to identify the tissue anatomy. The extra fluid contributing to the edema distributes in two phases: a volume equivalent to 5% of the leg volume is distributed throughout the leg tissue, while the excess fluid collects in a localized annulus lying adjacent to the fascia. The T1 in the annulus can be as high as 4 sec, indicating build up of free fluid in this region. Although most of this free fluid lies in the subcutaneous fat, there is a component which lies underneath the fascia in the muscle compartment.
我们利用T1加权磁共振成像（MR）来绘制股腘动脉搭桥术后水肿相关水分的分布情况。同时采集了自旋回波图像和真实参数T1图像。自旋回波图像用于识别组织解剖结构。导致水肿的额外液体分两个阶段分布：相当于腿部体积5%的液体分布于整个腿部组织，而多余的液体则聚集在紧邻筋膜的局部环状区域。该环状区域的T1值可高达4秒，表明该区域有游离液体蓄积。虽然大部分游离液体位于皮下脂肪中，但在肌肉间隙的筋膜下方也有一部分。
