³¹P MR spectroscopic imaging of the human prostate at 7 T: T₁relaxation times, Nuclear Overhauser Effect, and spectral characterization

Abstract

Knowledge of T1 relaxation times and NOE enhancements enables protocol optimization for (31) P MRSI of the prostate at 7 T. With a strongly reduced (31) P flip angle (≤ 45°), a (31) P MRSI dataset with optimal signal-to-noise ratio per unit time can be obtained within 15 minutes. The NOE enhancement can improve fitting accuracy, but its variability requires further investigation.
