Clinical history: multiple myeloma and temporal arteritis (inflammation and dammage to the blood vessels that supply the head, particularly the large or medium arteries that branch from the neck and supply the temporal area), weight loss.
PET scan for temporal arteritis can produce detailed images of the blood vessels and highlight areas of inflammation. PET imaging for atherosclerosis of carotid and peripheral arteries have been documented in several studies see below.
The patient was injected with 15 mCi F18 FDG and imaged from brow to mid-thigh at 1.5 hours post injection, with CT for attenuation correction. blood glucose at the time of injection was 90 mg/dl.
Findings - The images demonstrate diffuse metabolic activity in the carotid arteries suggesting active atherosclerosis or inflammation. Diffuse activity is present in the aorta, large vessels of the thorax, pelvis, upper and lower extremities...
There was no evidence of metabolically active neoplasm.
