Intravoxel Incoherent Motion (IVIM) offers the possibility to study microvascular perfusion properties of skeletal striated muscle. This study demonstrates the selective increase in IVIM perfusion parameters in subscapularis and posterior and lateral deltoid muscles after a lift-off test, which is a clinical test recognized to be selective for those muscles. This method is a promising new tool to investigate skeletal striated muscle physiology as well as perfusion-related muscular disorders, such as peripheral arteriopathies and diabetes mellitus-related microangiopathies.
