We perform transperineal MRI-guided biopsies for prostate cancer at the wide-bore 3T MRI scanner in AMIGO. The wide-bore 3T MRI (Siemens), combined with custom built software and hardware, was made possible through NIH grants, enabling us to launch this unique and clinically useful program from the inception of the AMIGO suite. Men with either recurrent prostate cancer post-surgeries or radiation treatments, or with consecutive negative ultrasound-guided biopsies but rising PSA are enrolled in our program.
In addition, we have recently begun a new clinical research program to investigate the feasibility of focal ablation therapies for prostate cancer using MRI-guidance. Extending the software, hardware, and multi-parametric MRI methods developed in MRI-guided biopsies, we perform cryoablation of the dominant lesion to manage cancer recurrence following treatments. In the patients who have been successfully treated so far, the advantage of planning, targeting, and guidance under wide bore 3T MRI in AMIGO has been demonstrated. The wide bore scanner allows patients to remain in the scanner during the placement of the cryoablation probe under MRI guidance. By keeping the patients statically in the scanner, a detailed ablation plan, produced at the beginning of the procedure, can be overlaid onto the intra-procedural images without image registration, a significant advantage over other potential approaches in which the patient would be moved into the scanner for imaging, then out of the scanner for ablation probe placement.
