Brief Summary

Currently, patients suspected of having prostate cancer undergo an MRI followed by targeted biopsies of any suspicious lesions under trans-rectal ultrasound (TRUS) guidance. This pathway is labour, time, and cost-intensive. Additionally, TRUS-MRI-Fusion devices are needed, which overlay the MRI scan onto the TRUS used for biopsies. This can lead to targeting errors due to mismatched images. Although biopsies can be performed in the MRI scanner to reduce these errors, it requires a significant amount of time within an expensive MRI scanner in the radiology department, along with special MRI-compatible equipment. Portable MRI technology has the potential to reduce these errors and streamline the diagnostic pathway to one visit. The Promaxo portable MRI is an FDA-cleared MRI device for MR-guided procedures. It uses a novel "truly" open MRI with an unobstructed field of view and a central aperture for robotic-guided intervention and has a limited footprint, allowing it to be placed in a standard operating theatre or large clinic room. The strength of the magnet is also low enough that special precautions and equipment are not needed to take biopsies. The intention is to conduct a study that answers the following research question: How does the accuracy of targeted biopsies of the prostate performed under the guidance of a portable MRI scanner compare to TRUS-MRI-fusion biopsies? Design: A single-arm, single-center IDEAL stage 2a study (n=85 patients) of patients undergoing prostate biopsy for suspected prostate cancer, where each patient would undergo both a portable MRI-registered biopsy and a TRUS-image-fusion biopsy. To reduce the risk of bias between the two modalities, the order of the modality will be randomized 1:1. There will be no blinding of the surgeon. The primary outcome will be the technical feasibility of performing portable MRI and portable MRI-targeted biopsies and estimates on cancer detection.

Study Arms (1)

Patients with suspected prostate cancer

OTHER

Patients who undergo prostate biopsy for suspected prostate cancer. Each patient would undergo both a portable MRI-registered biopsy and a TRUS-image-fusion biopsy. To reduce the risk of bias between the two modalities, the order of the modality will be randomized 1:1. There will be no blinding of the surgeon.

Device: Promaxo portable MRI
