Effect of flip angle and bandwidth on prostate visibility and artifacts.

Abstract

<p>Flip angle of A: 30° vs B: 40° vs C: 50° at BW of ±62.5 kHz. Bandwidth of D: ±31.25 kHz vs E: ±62.5 kHz vs F: ±83.3 kHz. Red arrowheads indicate prostate boundaries. White arrows point to fat pad used for CNR calculations (FP) and to inguial lymph nodes (ILN). Scale bar is 1 cm. Scan parameters: Axial scan, FOV 3×3 cm, 200 µm isotropic resolution, TR/TE = 3.3–4.6 ms/1.1–2.3 ms, 4 PC, 2 NEX, 14 minutes.</p
