BACKGROUND The purpose of this study was to combine intraoperative gamma probe (GP) detection with preoperative fluorine 18-fluoro-2-deoxy-glucose positron emission tomography (18F FDG-PET) imaging in order to improve detection of tumor recurrence in colorectal cancer (CRC) patients. METHODS Twenty-one patients (12 females, 9 males) with a mean age of 54 years (range 31-78) were enrolled. Pat...

3Department of Neurology, University of Pittsburgh Medical Center, Pittsburgh, PA 15213. ET with 18F-FDG combined with CT (PET/CT) enables precise localization of FDG uptake to particular structures and is useful for the detection and staging of several malignancies [1–3]. However, benign processes also can result in false-positive 18F-FDG uptake [4, 5]. We report the case of a 31-year-old woma...

Introduction: F-18 Fluorodeoxyglucose Positron Emission Tomography (18F-FDG PET/CT) is a hybrid non-invasive imaging tool that integrates PET and CT into single device. It used to detect measure metabolic activity in cancer cell and, hence, can provide anatomic information. 18F-FDG PET/CT useful for the detection of loco-regional recurrence, distant metastases, monitoring therapy response patie...

BACKGROUND The aim of this study is to describe the value of 2-deoxy-2-[18F]fluoro-D-glucose positron emission tomography/computed tomography (18F-FDG PET/CT) in diagnosing chronic Q fever in patients with central vascular disease and the added value of 18F-FDG PET/CT in the diagnostic combination strategy as described in the Dutch consensus guideline for diagnosing chronic Q fever. METHODS 1...

UNLABELLED In murine models, resection of a primary tumor leads to increased vascularization and accelerated growth of metastases that previously had remained microscopic. To study such a potentially inhibitory effect of primary tumors on the outgrowth of distant metastases in humans, we assessed the metabolic activity of liver metastases by 18F-FDG PET before and after resection of primary col...

herein, we report the f-18 fluorodeoxyglucose (18f-fdg) positron emission tomography (pet)/computed tomography (ct) findings of a benign solitary fibrous tumor (sft) of the kidney. the patient was a 63-year-old woman with a mass in the right kidney (10×9.7 cm), incidentally found on ct images. the ct scan showed a lobulated tumor arising from the hilum of the right kidney. the tumor consisted o...

Purpose: To determine the value of diffusion-weighted MRI (DWI-MRI) for treatment response assessment in 2-[18F]fluoro2-deoxy-D-glucose (FDG)–avid lymphoma. Experimental Design: Patients with FDG-avid Hodgkin (HL) or non-Hodgkin lymphoma (NHL) at pretherapeutic 18F-FDGPET/CT, who had also undergone pretherapeutic whole-body DWI-MRI, were included in this prospective study. Depending on the hist...

UNLABELLED The clinical utility of 18F-FDG PET in evaluating salivary gland malignancies has not been well defined. We therefore evaluated the utility of 18F-FDG PET in management for patients with salivary gland cancers. METHODS Thirty-four patients with newly diagnosed salivary gland cancers underwent CT and 18F-FDG PET before surgical resection with radiotherapy. The diagnostic accuracies ...

BACKGROUND Thyroid nodules with indeterminate fine-needle aspiration biopsy (FNAB) results remain a diagnostic dilemma, because 70 - 85% of these nodules have been found to be benign after thyroid surgery. OBJECTIVES The purpose of this study was to evaluate the usefulness of 18F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) in the preoperative diagnosis o...

BACKGROUND The aim of this study was to investigate whether the maximum standardized uptake value (SUVmax) measured on fluorine-18 fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) could be used as the primary means of differential diagnosis of thyroid nodules when tumor volume is assessed. METHODS We studied 192 patients who underwent preoperative 18F-FDG P...
