[¹⁸F]fluciclovine-PET/MRI images from a patient with prostate cancer status post radical prostatectomy with subsequent biochemical recurrence and a PSA of 8.8 ng/mL. The T2 single shot fast spin echo (SSFSE) MR images demonstrate a large right internal iliac lymph node (A, open arrow) with markedly increased tracer activity on the fused PET/MR image (B) and a normal-sized left paraaortic lymph node (C, filled arrow) with increased activity on the fused PET/MR image (D), suspicious for an additional nodal metastasis. Whole body MIP image (E) demonstrates no additional distant metastases.
