This technical development study demonstrated the feasibility of diagnostic intervention using HP-13C pyruvate MRI. HP-MRI was integrated into the diagnostic prostate mpMRI workflow, complete with identification of C13 research targets and sampling of these targets in fusion biopsies.
Figure 4. A summary of biopsy results from each patient following the hyperpolarized 13C study and radiologist targeting session. Low-grade cancer involvement was found in the cores corresponding to the C13 targets in 2 out of 3 patients. All the C13-mpMRI studies and the biopsies were safe and successful without adverse events.
Figure 1. This figure illustrates the workflow of HP-13C MR research targeting of the prostate, based on pyruvate-to-lactate conversion (kPL) abnormalities. The HP-13C MR exam and research targeting was integrated into the standard-of-care mpMRI fusion and systematic biopsies at our institution.
