History
69-year-old male patient with a history of radical prostatectomy for cancer prostate from a year ago.
He is presenting now with re-elevation of PSA level reaching 0.7ng/ml.
Exam Technique:
• Patients weight: 80 Kg
• Injected Dose: 333MBq
• Time per frame: 80 sec
• Reconstruction protocol: UltraHD (PSF+TOF)
• Scanner: Biograph Horizon
18F-PSMA-PET/CT exam revealed:
• Local operative bed small (7mm) enhancing PSMA-avid nodule, denoting local recurrence.
• Three sub centimetric PSMA-avid lymph nodes at perirectal and right obturator regions. The largest lymph node was 6 mm and the smallest lymph node measured 3.5mm.
Take home message:
• PSMA-PET/CT imaging revolutionized prostate cancer imaging with the ability to detect tiny lesions as in this case, that could not be detected by any other modality.
