BACKGROUND & OBJECTIVE Because (18)F-FDG PET/CT can display cancer lesion morphology, size and the relatinship of the cancer lesion to adjacent tissues, it is used in the diagnosis and classification of nasopharyngeal carcinoma (NPC). This study was to explore the application value of (18)F-FDG PET/CT in TNM staging by comparing the performance of MRI and PET/CT together with pathological resul...

The role of integrated (18)F-2-fluoro-2-deoxy-D-glucose positron emission tomography computed tomography (PET-CT) is uncertain in gallbladder cancer. The aim of this study was to show the role of PET-CT in gallbladder cancer patients. Fifty-three patients with gallbladder cancer underwent preoperative computed tomography (CT) and PET-CT scans. Their medical records were retrospectively reviewed...

PET/MRI represents a promising hybrid imaging modality with several potential clinical applications. Although PET/MRI seems highly attractive in the diagnostic approach of multiple myeloma (MM), its role has not yet been evaluated. The aims of this prospective study are to evaluate the feasibility of 18F-FDG PET/MRI in detection of MM lesions, and to investigate the reproducibility of bone marr...

Stanford University, Department of Radiology, Division of Nuclear Medicine and Molecular Imaging, USA Recently, a whole-body, simultaneous positron emission tomography magnetic resonance imaging (PET-MRI) system combing MRI with time-of-flight (TOF) PET has been developed. We present our initial experience with human clinical studies using 18Ffluorodeoxyglucase (FDG) with this scanner, in compa...

UNLABELLED The aim of this study was to investigate the diagnostic accuracy and impact on patient management of the new integrated PET/CT modality in patients with suspected iodine-negative, differentiated thyroid carcinoma (DTC). METHODS Forty patients with DTC and a suggestion of iodine-negative tumor tissue underwent PET/CT examination (370 MBq (18)F-FDG, coregistered PET/CT whole-body ima...

AIM The aim was to compare the imaging findings of (18)F-fluorodeoxyglucose ((18)F-FDG) PET and integrated PET/CT in patients with primary, recurrent or metastatic ovarian cancer. MATERIALS AND METHODS 21 women with ovarian cancer were evaluated. All patients had a integrated PET/CT scan. Localization, infiltration and uptake intensity of [(18)F]FDG were evaluated on PET and PET/CT. The certa...

Introduction: Clinical examination and even anatomical imaging may fail to identify primary site of malignancy in patients presenting with cervical nodal metastasis. 18F-Fluorodeoxyglucose Positron Emission Computed Tomography (18F-FDG PET-CT) is known to overcome the limitations of anatomic imaging. Methods: Sixty-three (63) patient...

introduction:myocardial 18f-fdg uptake is highly variable in oncologic whole body 18f-fdg pet/ct studies, ranging from quite intense to minimal distribution. intense or heterogeneous myocardial 18f-fdg uptake is undesirable as it may interfere with the visual or quantitative evaluation of tumoral invasion and metastases in pericardium, myocardium or adjacent mediastinal structures. the diet, as...
