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 کاملstimate bowtie filter shape in PET/CT scan with TLD
Introduction: The CT machine utilizes a bowtie filter to shape the X-ray beam and remove lower energy photons. Configuration of this bowtie filter is complex and its geometry is often not available in detail. It causes the CT dose index (CTDI) be with the different values in measurement versus Monte Carlo simulation studies and other analytical calculations. It is important esp...

متن کاملUse of Pet Scan in Lung Cancer
It is estimated that in early stage lung cancer, that PET scan shows unsuspected metastases in about 10% of patients. In a study led by MacManus et al, an evaluation was done for patients with Stage III non-small lung cancer to determine the role of treatment. Small cell lung cancer is a particular type seen under the microscope. Non-small cell refers to essentially all other types of lung canc...
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...
