Functional techniques are playing a pivotal role in the imaging of cancer today. Our aim was to compare, on a head-to-head basis, 3 functional imaging techniques in patients with histologically verified neuroendocrine tumors: somatostatin receptor scintigraphy (SRS) with 111In-diethylenetriaminepentaacetic acidoctreotide, scintigraphy with 123I-metaiodobenzylguanidine (MIBG), and 18F-FDG PET. M...
Unlike for most other malignancies, application of FDG PET/CT is limited for renal cell carcinoma (RCC), mainly due to physiological excretion of 18F-fluoro-2-deoxy-2-d-glucose (FDG) from the kidneys, which decreases contrast between renal lesions and normal tissue, and may obscure or mask the lesions of the kidneys. Published clinical observations were discordant regarding the role of FDG PET/...
PURPOSE To provide a first evidence-based review of the literature on the role of fluorine-18-fluorodeoxyglucose positron emission tomography and positron emission tomography/computed tomography (FDG-PET and PET/CT) in patients with colorectal liver metastases (CRLM) undergoing selective internal radiation therapy (SIRT) with yttrium-90 ((90)Y) microspheres. METHODS A comprehensive computer l...
CONTEXT The role of (18)F-labeled 2-fluoro-2-deoxy-d-glucose (FDG) positron emission tomography (PET)/computed tomography (CT) in the post-operative monitoring of patients with adrenocortical carcinoma (ACC) is still unclear. OBJECTIVE To assess the accuracy of FDG PET/CT to diagnose ACC recurrence in a real world setting. DESIGN AND METHODS Retrospective evaluation of data of 57 patients w...
OBJECTIVE To examine whether the clinical severity of cervical dystonia (CD) significantly correlates with (18)F-fluorodeoxyglucose positron emission tomography/computed tomography ((18)F-FDG PET/CT) findings as well as to determine the threshold of the clinical severity of CD for positive (18)F-FDG PET/CT study findings. METHODS Forty-seven subjects with torticollis as one of the symptoms of...
UNLABELLED Recent reports have indicated the value and limitations of (18)F-FDG PET and (201)Tl SPECT for determination of malignancy. We prospectively assessed and compared the usefulness of these scintigraphic examinations as well as (18)F-FDG PET delayed imaging for the evaluation of thoracic abnormalities. METHODS Eighty patients with thoracic nodular lesions seen on chest CT images were ...
BACKGROUND Multiple Myeloma (MM) is a B cell neoplasm causing lytic or osteopenic bone abnormalities. Whole body skeletal survey (WBSS), Magnetic resonance (MR) and 18F-FDG PET/CT are imaging techniques routinely used for the evaluation of bone involvement in MM patients. AIM As MM bone lesions may present low 18F-FDG uptake; the aim of this study was to assess the possible added value and li...
gliomas account for almost 80% of primary malignant brain tumors in adults. magnetic resonance imaging (mri) is still the gold standard for diagnosis of brain tumors and brain 99mtc-tetrofosmin single photon emission computed tomography (99mtc-tetrofosmin-spect) has been established as a useful tool for their evaluation. fluorine-18–2-fluoro-2-deoxy-d-glucose positron emission tomography/comput...
pleural epithelioid hemangioendothelioma (ehe) is a rare malignancy of vascular-endothelial origin with non-specific symptoms and an unpredictable outcome. diagnosis of this condition by imaging modalities is challenging, and no standard therapeutic approaches have been established in this regard. in this paper, we described the case of a patient with a low-grade fever, coughing and chest pain ...
BACKGROUND AND OBJECTIVES Accurate staging is essential in order to determine appropriate treatment in Hodgkin's disease (HD). (18)F-fluorodeoxyglucose positron emission tomography ((18)F-FDG PET) offers the advantage of metabolic imaging that is largely independent of morphologic criteria. In the present study we evaluated the role of (18)F-FDG PET compared to routine procedures for the stagin...
