Pet Scan results
INDICATION: 59-year-old man with prostate cancer diagnosed in
2014 with rising PSA. Subsequent treatment strategy.
DOSE: 10.0 mCi
TECHNIQUE: Approximately 3 - 5 minutes following IV tracer
administration via a right antecubital fossa vein, positron
emission tomography was performed from the vertex through the mid
thigh. Non-contrast helical CT imaging was performed over the
same range without breath-hold for attenuation correction of PET
images and anatomic correlation, but not for primary
interpretation as it is not of standard diagnostic quality. For
the CT portion of the study, the recorded CTDI volume was 3.69
mGy and DLP was 314.62 mGy*cm.
HEAD AND NECK: There is no suspicious lymphadenopathy. There is
no tracer-avid malignancy in the imaged portions of the head and
CHEST: There is no tracer-avid malignancy in the chest. There is
no axillary, supraclavicular, mediastinal or hilar
lymphadenopathy. There is no pleural or pericardial effusion.
There is no air-space disease or suspicious lung nodule. Coronary
ABDOMEN/PELVIS: There is a tracer avid 12 x 10 mm left internal
iliac node on axial 232. Tracer avid 6 x 4 mm right perirectal
node on axial 235. Increased tracer uptake in the posterior
aspect of the prostate gland bilaterally. Brachytherapy beads in
the prostate. Colonic diverticulosis. Mild calcification of the
aorta and its branches.
MUSCULOSKELETAL: There is no tracer-avid or destructive bone
Mild tracer uptake associated with cutaneous thickening in the
anterior abdominal wall, recommend direct inspection.
1. Tracer uptake in the prostate gland is suspicious for local
recurrent prostate cancer.
2. Tracer-avid left internal iliac node and right perirectal
node are suspicious for regional nodal recurrence.
