False-positive FDG PET CT Scan in Vertebral Hemangioma
FDG PET CT scan is considered to be a sensitive tool to detect skeletal metastasis in known malignancies. However, it’s high sensitivity and low specificity may account for false positive diagnosis in cases of trauma, infection, inflammation and other benign conditions. Skeletal hemangioma is one of the common benign conditions which are typically ametabolic on FDG PET CT with no uptake on bone...
متن کاملFalse positive PET scan deserves attention.
PURPOSE Pulmonary focal lesions are frequently identified incidentally. Furthermore, a final diagnosis is really a considerable problem for patients having risk factors for malignancy or particularly for a newly detected nodule during the postoperative period after any kind of lung surgery. For treatment decisions, the nature of the lesions needs to be clarified. Relatively recently positron em...
متن کاملMeningioma: A false positive finding of metastasis from prostate adenocarcinoma using 68Ga-PSMA PET/CT scan
A 73-year-old man with history of prostatic adenocarcinoma radical prostatectomy underwent 99mTc-MDP whole-body bone scan and subsequent 68Ga-labeled prostate-specific membrane antigen (PSMA) ligand PET/CT for restaging due to a gradual rise of prostate-specific antigen levels. Whole-body bone scan showed two focal zones of slightly increased uptake in the right fronto-par...
متن کاملFalse Positive and False Negative FDG-PET Scans in Various Thoracic Diseases
Fluorodeoxyglucose (FDG)-positron emission tomography (PET) is being used more and more to differentiate benign from malignant focal lesions and it has been shown to be more efficacious than conventional chest computed tomography (CT). However, FDG is not a cancer-specific agent, and false positive findings in benign diseases have been reported. Infectious diseases (mycobacterial, fungal, bacte...
متن کاملFalse-positive and false-negative rates for carcinogenicity screens.
The implementation of a number of chemical carcinogen screening programs has been accompanied by the observation that some screens might have high false-positive error rates. With designs presently used at the National Cancer Institute and historical spontaneous tumor rates based upon control animals in previous experiments, we compute upper bounds on the false-positive error rates for several ...
