| Popis: | The evaluation of local muscle recruitment during a specific movement can be done indirectly by measuring changes in local blood flow. Intravoxel incoherent motion perfusion imaging exploits some properties of the magnetic resonance to measure locally microvascular perfusion, and seems ideally suited for this task. We studied the selectivity of the increase in intravoxel incoherent motion blood flow related parameter fD* in the muscles of 24 shoulders after two physical exam maneuvers, Jobe and Lift-off test (test order reversed in half of the volunteers) each held 2 min against resistance. After a lift-off, IVIM blood flow-related fD* was increased in the subscapularis (in 10−3 mm2 s−1, 3.24 ± 0.86 vs. rest 1.37 ± 0.58, p |
