Thank you for your advice and help.
Here is the extract from my PSMA PET scan result today and what this SUV 4.6 in prostate Gland means?
EXAM: PSMA PET/CT VERTEX TO DISTAL THIGH
HISTORY
: Initial treatment. 66 year old male with C61 malignant neoplasm of prostate, unfavorable intermediate risk. Staging prior to treatment.. PSA up to 4.9.
PET/CT REQUESTED FOR
: Initial treatment strategy.
RADIOPHARMACEUTICAL
: 9.9 mCi F18 DCFPyL IV (PSMA)
TECHNIQUE
: This is a combined PET/CT scan. PET is performed from top of skull to knees after a 62 minute uptake phase. CT is performed without oral or IV contrast.
Physiological distribution of tracer is seen within the salivary glands and lacrimal glands, blood pool, liver, spleen, pancreas, ganglia, bone marrow, bowel, kidneys and urinary tract.

SUV reference:
SUV max parotid/salivary glands: 18.1
SUV max right hepatic lobe: 9.3
SUV max descending thoracic aorta: 1.3

PSMA - expression score:
High (3) SUV parotid/salivary glands
Intermediate (2) SUV liver
Low (1) SUV blood pool

THORAX: No increased uptake in the lungs or mediastinum. No suspicious pulmonary nodules. No pleural or pericardial effusions.
ABDOMEN/PELVIS:
Evaluation of prostate bed: There is a focus of abnormal uptake with maximum SUV of 4.6 in the posterolateral right lobe (slice 279) at the mid gland level. No involvement of the seminal vesicles.
Evaluation of lymph nodes: No increased uptake in pelvic, retroperitoneal, or abdominal nodes.
No increased uptake in the liver or spleen. Liver and spleen are not enlarged. No hydronephrosis. No adrenal nodules. Pancreas is unremarkable.
BONES/BONE MARROW: No increased uptake in the skeleton and no suspicious lytic or blastic lesions.

IMPRESSION:
1. PSMA avid malignancy in the right lobe of the prostate as above. No evidence for extraprostatic disease.

Thank you for the opportunity to participate in the care of this patient.
