Incidental findings are common on PET and should not be ignored as the consequences can be perilousFDG uptake on PET is non-specific for malignancyThere has to be strong, clear and direct communication of incidental findings from imaging specialists to referrers and treating cliniciansIncidental ...
proximalcolon (53 %) than in the distal colon (81 %). A factorpartially explaining this is that f l at lesions were morecommon proximally. We investigated incidental focalcolonic FDG uptake in patients referred FDG-PET/CTscans [5]. In our study, we showed that the positive pre-dictive va...
Allpatients suffering from non-small cell lung CA (NSCLC) having avid subcentimeter nodes on FDG-PET/CT were included. The findings obtained on FDG-PET/CT were correlated with histopathological findings after endobronchial ultrasound(EBUS). The results were...
A 56-year-old female patient was referred for an FDG PET/CT scan (Fig. 77.1) during the follow-up of a dedifferentited pancreatic neuroendocrine tumor. She was also affected by portal thrombosis. The scan was negative for neuroendocrine tumor relapse, but areas of increased uptake in the p...
27 Additionally, checkpoint inhibitors may cause inflammation and elevated FDG uptake in other organs as well leading to nonspecific findings on FDG-PET/CT such as possible arthritis or colitis.28 Effect of Kidney and Liver Failure FDG is primarily eliminated through the kidneys. In patients with ...
False negative findings Common causes of false negative 2-[18F]FDG-PET findings are as follows [26, 59, 60]: (1) small lesions measuring ≤ 10 mm (or 4–5 mm in digital PET scanners [61]), (2) low-grade tumours, (3) certain histologic subtypes (e.g. lobular, tubular, carci...
In addition, we examined the number and type of diagnostic procedures preceding the PET/CT scan and whether the findings on the PET/CT resulted in change of therapy. Methods A retrospective study was performed in two university medical centres in the Netherlands (University Medical Center Utrecht ...
Clinical assessments, blood samples, and FDG PET/CT images were obtained at enrolment and again after 3 weeks. The median age of the patients was 65 years; 9 (52.9%) patients were male. On initial FDG PET/CT, the eschars showed markedly increased FDG uptake on PET imaging that improved ...
FDG-PET/CT scans revealed elevated FDG-uptake in lungs of five patients subsequently diagnosed with active (n=3) or clinically inactive (n=2) tuberculosis. Uptake magnitude was unrelated to disease activity. These findings suggest that tuberculosis latency may include periods of percolating ...
We present our experience with incidentally detected TT on FDG PET/CT in 21 oncologic patients.We retrospectively reviewed all FDG PET/CT examinations during a 5-year period at the Army Hospital Research and Referral in New Delhi, India, and included all oncology cases with FDG-avid thrombosis ...
