Horizons of Diagnosis and Treatment with PSMA PET MRI
Paul D. Maroni, MD, discusses advancements in prostate cancer imaging, emphasizing PSMA PET/MRI. Recent trends show that most new patients arrive with MRIs or even PSMA PET/CT scans; however, access to PSMA PET/MRI remains limited due to approval issues.
In this 10-minute presentation, Dr. Maroni highlights findings from the Primary Trial, which combines MRI and PSMA PET to screen for clinically significant cancers. This fusion is highly specific in identifying high-risk patients, potentially bypassing biopsies in specific cases. Moreover, studies in Canada are investigating PSMA PET/MRI’s role in guiding treatments like SBRT and focal ablation, indicating its potential as a prognostic and predictive biomarker.
Maroni suggests PSMA PET/MRI could serve in initial workups, replacing PET/CT, and aiding in post-treatment follow-up to assess cure or recurrence. There’s also interest in advancing fusion technology to overlay PSMA PET with pre-existing MRIs, optimizing cost-effectiveness and patient care by minimizing additional radiation.
