摘要

基于体素内非相干运动（ivim） mri的灌注分数和水扩散图来自年轻（27岁）和老年（90岁）受试者在休息和每隔3.25分钟进行动态膝关节伸展运动后的上肢。活跃的股直肌（红色）和部分不活跃的大收肌（白色）的感兴趣区域。注意运动后年轻受试者和老年受试者灌注分数的显著差异。摘自adelnia等人。经JOHN WILEY &；儿子,INC。胡伊曼斯等人（535-560）

Exercise MR of Skeletal Muscles, the Heart, and the Brain

INTRAVOXEL INCOHERENT MOTION (IVIM) MRI-BASED PERFUSION FRACTION AND WATER DIFFUSION MAPS FROM THE UPPER LEG OF A YOUNG (27 YEARS) AND AN OLD (90 YEAR) SUBJECT AT REST AND AFTER DYNAMIC KNEE EXTENSION EXERCISE AT 3.25-MINUTE INTERVALS. REGIONS OF INTEREST FOR THE ACTIVE RECTUS FEMORIS MUSCLE (RED) AND FOR A PART OF THE INACTIVE ADDUCTOR MAGNUS MUSCLE (WHITE) ARE INDICATED. NOTE THE PRONOUNCED DIFFERENCE IN PERFUSION FRACTION BETWEEN THE YOUNG AND OLD SUBJECTS AFTER EXERCISE. REPRODUCED FROM ADELNIA ET AL. WITH PERMISSION FROM JOHN WILEY & SONS, INC. BY HOOIJMANS ET AL.
