Value of Fused ¹⁸F-Choline-PET/MRI to Evaluate Prostate Cancer Relapse in Patients Showing Biochemical Recurrence after EBRT: Preliminary Results

Figure 2

75-year-old man with biopsy-proven local PC recurrence after EBRT. T2-weighted axial image (a) demonstrates a hypointense area (arrow) in the posterior left lateral aspect of the prostate apex. The ADC map (b) demonstrates that the hypointense nodular area has lower ADC values than the surrounding parenchyma (arrow). On ¹⁸F-Choline-PET axial scan (c) a well-defined PET-positive focus is appreciable (arrow). Fused ¹⁸F-Choline-PET/MRI image (d) shows exact correspondence between PET-positive focus and MRI finding (arrow).
