Vascular prosthetic graft infection (VPGI) is a severe complication after vascular surgery. CT-scan is considered the diagnostic tool of choice in advanced VPGI. The incidence of a false-negative result using CT is relatively high, especially in the presence of low-grade infections. (18)F-fluorodeoxyglucose positron emission tomography ((18)F-FDG PET) scanning has been suggested as an alternati...

BACKGROUND Net cellular uptake of (18)F-FDG is adversely affected by elevated plasma glucose levels. The purpose of our study was to investigate the influence of hyperglycemic state at the time of (18)F-FDG injection on the diagnostic accuracy of (18)F-FDG PET/CT. METHOD Pre-scan plasma glucose levels of all patients who were referred for PET/CT with an oncologic indication during the year 20...

BACKGROUND Limited data suggest that fluorine-18 fluoro-2-deoxy-D-glucose (F-18 FDG) positron emission tomography combined with computed tomography (PET/CT) scan may be useful for diagnosing infections of the spine. Brucellar spondylodiskitis might be devastating and current imaging techniques lack sensitivity and specificity. The aim of this prospective study was to determine the role of F-18 ...

A 51-y-old man underwent (18)F-FDG PET for disease restaging of non-Hodgkin's lymphoma. Initial attenuation correction images demonstrated unilateral hemispheric cerebral hypometabolic activity. The remainder of the scan was otherwise unremarkable. Non-attenuation correction images demonstrated a patient motion artifact attributable to lateral movement of the patient's head during image acquisi...

Basosquamous carcinoma (BSC) is a rare type of malignancy with features of both basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) with a potential for aggressive behaviour infiltration and destruction. First reported by MacCormac in 1910 in a series of rodent ulcers, this entity does have an increased risk of recurrence and metastases as well, which distinguish it from other forms ...

OBJECTIVES The present study aimed to evaluate the role of pre-therapeutic (18)fluorine-fluorodeoxyglucose positron emission tomography-computed tomography ((18)F-FDG PET-CT) and maximum standardized uptake value (SUVmax) in guiding the treatment strategy and predicting the prognosis of esophageal carcinoma, using the survival data of the patients. METHODS The present retrospective, cohort st...

BACKGROUND (18)F-FDG PET/CT is widely utilized in the management of cancer patients. The aim of this paper was to comprehensively describe the specific methodology utilized in our single-institution cumulative retrospective experience with a multimodal imaging and detection approach to (18)F-FDG-directed surgery for known/suspected malignancies. METHODS From June 2005-June 2010, 145 patients ...

UNLABELLED Medullary thyroid carcinoma (MTC) is a rare endocrine tumor arising from the C-cells of the thyroid gland. Calcitonin is the principal serum tumor marker. A rising calcitonin level after total thyroidectomy for localized disease generally indicates residual, recurrent, or metastatic disease. The role of (18)F-FDG PET in MTC remains somewhat unclear. We reviewed our own experience wit...

UNLABELLED (18)F-FDG PET is increasingly used for lung cancer; however, some insufficient results have been reported. The purpose of this study was to evaluate the efficacy of dual-time-point (18)F-FDG PET for staging lung cancer and for differentiating metastatic from nonmetastatic lung cancer lesions. METHODS One hundred fifty-five lung cancer patients with known or suspected mediastinal an...
