BACKGROUND The detection of solitary pulmonary nodules (SPNs) that may potentially develop into a malignant lesion is essential for early clinical interventions. However, grading classification based on computed tomography (CT) imaging results remains a significant challenge. The 2-[18F]-fluoro-2-deoxy-D-glucose (18F-FDG) positron emission tomography (PET)/CT imaging produces both false-positiv...

The aim of the present retrospective study was to evaluate the sensitivity and specificity of fluorodeoxyglucose (18F-FDG) positron emission tomography/computed tomography (PET/CT) in assessing the recurrence of colorectal cancer (CRC) with regard to carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA 19-9). 18F-FDG PET/CT was performed in 100 patients for the re-staging of CRC. Th...

OBJECTIVE AND METHODS The aim of this study was to evaluate myocardial viability in patients after acute myocardial infarction (AMI). We compared 201Tl SPECT after 201Tl with GIK (10% glucose 250 ml, insulin 5 U and KCl 10 mEq) infusion (GIK-201Tl) with resting 201Tl and 99mTc-pyrophosphate (PYP) dual SPECT, positron emission computed tomography (PET) using 18F-fluorodeoxyglucose (18F-FDG) in 2...

BACKGROUND Thyroid incidentalomas detected by 2-deoxy-2-18F-fluoro-D-glucose positron emission tomography/computed tomography (18F-FDG PET/CT) have been reported in 1% to 4% of the population, with a risk of malignancy of 27.8% to 74%. We performed a retrospective review of FDG-avid thyroid incidentalomas in cancer screening subjects and patients with nonthyroid cancer. The risk of malignancy i...

necrotizing fasciitis is a part of a spectrum of necrotizing soft tissue infections that usually follow a surgical intervention or a chronic / acute medical illness. diagnosis is often based on symptoms which classically start within hours after an injury. there are no reports on the use of pet/ct in this condition. sparing reports of its association in patients with malignancy (ca of colon and...

AIM To determine the significance and need for investigation of incidental prostatic uptake in men undergoing 18F-labelled fluorodeoxyglucose (18F-FDG) positron emission tomography/computed tomography (PET/CT) for other indications. METHODS Hospital databases were searched over a 5-year period for patients undergoing both PET/CT and prostate magnetic resonance imaging (MRI). For the initial a...

BACKGROUND To our knowledge, data are lacking on the role of 18F-FDG PET/CT in the localization and prediction of neuroendocrine tumors, in particular the pheochromocytoma/paraganglioma (PCC/PGL) group. PURPOSE To evaluate the role of 18F-FDG PET/CT in localizing and predicting the malignant potential of PCC/PGL. MATERIAL AND METHODS Twenty-three consecutive patients with a history of PCC/P...

PURPOSE To compare the diagnostic value of 99Tcm-MIBI- SPECT and 18F-FDG-PET/CT in differentiating benign from malignant solitary pulmonary nodules (SPNs). METHODS 170 SPNs were involved in this study (78 with 99Tcm-MIBI-SPECT and 92 with 18F-FDG-PET/CT). Definite diagnosis of SPNs was determined by biopsy. The diagnostic efficiency of 99Tcm-MIBI-SPECT and 18F-FDGPET/ CT in differentiating be...

UNLABELLED Benign and malignant pulmonary lesions usually are differentiated by 18F-FDG PET with a semiquantitative 18F-FDG standardized uptake value (SUV) of 2.5. However, the frequency of malignancies with an SUV of <2.5 is significant, and pulmonary nodules with low 18F-FDG uptake often present diagnostic challenges. METHODS Among 360 consecutive patients who underwent 18F-FDG PET to evalu...

We report a rare case of vascular graft-associated aneurysmal angiosarcoma by 18F-Fluorodeoxyglucose (FDG) positron emission tomography (PET). An 81-year-old male patient, with a prior history of graft interposition 1 year previously, was referred to 18F-FDG-PET because of an inflammatory syndrome of unknown origin. FDG-PET images revealed a particular pattern of intense circular uptake within ...
