Clinical History

This an 81-year-old female who was found to have two large masses within the lower lobes of her lungs and a smaller, spiculated lesion within the right middle lobe on a recent CT scan of the chest at an outside facility dated three months prior to the PET scan.

Technique

The patient was intravenously administered 10.8 mc of F18 FDG, and following 45 minutes, whole body imaging under the PET scanner with computer reconstruction images in multiple planes was performed. Evaluation was made for uptake of FDG activity.

Findings


1. There is normal physiologic uptake of FDG within the visualized brain, parts of the GI tract, liver, heart, kidneys and urinary bladder.
2. There are no abnormal areas of increased metabolic uptake within the lungs to correspond with the CT findings.
3. There are no other abnormal areas of uptake with the exception of a mildly increased area uptake within the left acromioclavicular joint. This could represent a sebaceous cyst or degenerative change within the left shoulder. It is probably of little clinical significance.

Impressions


NO ABNORMAL AREAS OF INCREASED METABOLIC UPTAKE TO SUGGEST A METABOLICALLY ACTIVE TUMOR.
