Prostate magnetic resonance imaging at 3 Tesla: Is administration of hyoscine-N-butyl-bromide mandatory?

Figure 1 Flowchart of patient inclusion. Total of 70 patients were selected randomly out of the hyoscine-N-butyl-bromide (HBB) and the corresponding control group. MRI: Magnetic resonance imaging.

Figure 2 Average scores of the obtained imaging categories in both groups. No statistical significant difference could be obtained. HBB: Hyoscine-N-butyl-bromide.

Figure 3 The results demonstrated no significant effect of administration of hyoscine-N-butyl-bromide on visualisation of the prostate, iliac lymph nodes, periprostatic artefacts, and overall image quality. A: 54-year-old patient. Coronal T2w-TSE sequence after administration of hyoscine-N-butyl-bromide (HBB): Prostate capsule (arrows) and neurovascular bundles are well visualized. Central gland and peripheral zone can be differentiated. Bowel wall structures are sharply depicted without artefacts (arrowheads); B: 72-year-old patient after coronal T2w-TSE sequence without administration of hyoscine-N-butyl-bromide (HBB): Qualitative rating showed no significant difference in visualisation of prostate capsule (white arrow), differentiation between central and peripheral gland, and neurovascular bundle structures (black arrow). However, ill-defined and blurred small bowel loops with surrounding artefacts occurred (arrowheads) without affecting the prostate or periprostatic space.
