Abstract

Quantitative maps obtained in two representative participants in the younger (age = 26 years, male) and older (age = 58 years, male) groups, at Visit 1 for both field strengths (1.5 T and 3 T). The images arranged from left to right include: Perfusion weighted images (pixel values are PWS in %) for six post-labeling delays (PLDs = 0.4, 0.7, 1, 1.3, 1.6, and 1.9 s); renal blood flow (RBF) map (mL/min/100 g) calculated using the single-delay data for the PLD of 1.3 s; RBF (mL/min/100 g) and arterial transit time (ATT) maps (s) calculated using the multi-delay data; and T₁ map (ms).

场强、性别和年龄对肾脏伪连续动脉自旋标记和T1定位的影响

在第一次访问时，获得了两组具有代表性的年轻（年龄= 26岁，男性）和年长（年龄= 58岁，男性）两组的定量图，用于测量场强（1.5 T和3 T）。从左至右排列的图像包括：6个标记后延迟（pld = 0.4、0.7、1、1.3、1.6、1.9 s）的灌注加权图像（像素值为PWS %）；单延迟数据计算肾血流图（mL/min/ 100g）， PLD为1.3 s；RBF （mL/min/ 100g）和动脉运输时间（ATT）图(s)使用多延迟数据计算；T1图（ms）。作者：Garcia-Ruiz等人（1180-1195）
