Overview

Supports preclinical feasibility of endorectal coil actuation for prostate MRE; hypothesis-generating for human translation.

Structured PICO

P
Population
Prostate phantom with embedded 'lesions' (6 mm diameter) and a porcine model
I
Intervention
MR elastography (MRE) at 3 Tesla using a modified commercial endorectal imaging coil as an actuator (actuation frequencies 50-200 Hz)
O
Outcome
Technical feasibility of generating shear waves and measuring shear modulus G mapssurrogate

A modified commercial endorectal coil can feasibly act as an actuator for MR elastography of the prostate, successfully differentiating tissue stiffness in phantom and porcine models.

Limitations

  • Diagnostic value needs to be determined in further trials
