For semi-quantitative analysis, a region of interest (ROI) was drawn around the site of the abnormal uptake in the consequent 4 6 PET/CT slices.
On the other hand, there was a higher frequency of the appearance of rapid eye movement (REM) sleep behavior disorder in the abnormal MIBG uptake group than the normal MIBG uptake group.
c Four-chamber FDG-PET scan shows no abnormal uptake in the mass, indicating a benign mass.
b Fluorodeoxyglucose-positron emission tomography shows abnormal uptake in the left lung tumor, bilateral hilar lymph nodes, and left supraclavicular lymph nodes.
FDG PET reveals abnormal uptake in the aortic arch or large thoracic arteries in more than half of affected patients (sensitivity 56%%, specificity 98%%, positive predictive value 93%%, negative predictive value 80%%) [11, 50].
The top row (a, fused transaxial PET/CT images) show no abnormal uptake in the knees, whereas the PET/CT performed at week 16 show bilateral synovitis, especially in the right knee (b) Open image in new window Fig. 2 A 29 years old patient with RA diagnosed 2 years ago.
After the surgery, testicular ultrasound imaging and abdominal, pelvic, and cerebral CT showed no apparent tumor or enlarged lymph nodes; however, an abnormal uptake in the right mesenteric lymph node was pointed out by 18F-fluorodeoxyglucose-positron emission tomography (FDG-PET) scan.
Persistent abnormal uptake in the cervix or lymph nodes was found in 20 patients, and their cause-specific survival was 32%.
His total body bone scan showed no abnormal uptake in the skull and CT of brain was negative for metastatic disease.
Two different studies have shown abnormal uptake in the spine of PMR patients at the level of the spinous processes [ 14, 15], without a precise anatomical localization of the inflammation.
