Elevated T1 (1234 ms vs 1213 ms), T1ρ (67.7 ms vs 56.9 ms), mFI (22.1 ms vs 13.3 ms), and ECV (0.44 vs 0.26) can be observed in the enhancement region compared to the remote lateral segment, while T2 shows no obvious difference between the hyperintense area ...
A T1MES prototype phantom containing 12 vials with different T1and T2values for cardiac T1mapping at 3 T was used [35]. Reference T1and T2of phantom vials were measured by inversion-recovery spin-echo (IR-SE) and Carr-Purcell-Meiboom-Gill spin-echo (CPMG-SE), respectively. MOLLI5(3)3,...

Eighteen asymptomatic participants with no history of low back pain (LBP),injury, or surgery underwent magnetic resonance (MR) imaging of theirlumbar spineprior to and immediately following a treadmill walking “stress test.” Anatomic (SPACE, FLASH) MR images were obtained pre- and post-exercise...
Spontaneous amygdala activity and functional connectivity were assessed during resting-state functional MRI. A brief battery of standardized neuropsychological tests was admi- nistered outside of the MRI scanner to assess three domains of cognitive function: executive functions, psychomotor speed, and ...
