UNLABELLED The purpose of this study was to compare the diagnostic utility of (123)I-metaiodobenzylguanidine ((123)I-MIBG) scintigraphy and (18)F-FDG PET in neuroblastoma. METHODS A total of 113 paired (123)I-MIBG and (18)F-FDG PET scans in 60 patients with neuroblastoma were retrospectively reviewed. Paired scans were acquired within 14 days of each other. RESULTS For stage 1 and 2 neurobl...

This study was aimed to investigate the significance of 18F-FDG PET/CT in secondary hemophagocytic lymphohistiocytosis (sHLH) patients. A total of 18 patients received 18F-FDG PET/CT scan at initial diagnosis. All patients (18/18) had at least 3 organs involved, with increased FDG metabolism in different degrees. Fifteen cases (15/18) had definite underlying diseases, including infections (IAHL...

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...

OBJECTIVES To evaluate the correlation of MRI and [(18)F]FDG-PET scans with the clinical course and inflammatory markers in patients with aortitis. METHODS Eight patients with aortitis presenting with unspecific GCA-like symptoms were examined. Aortitis was diagnosed and followed up by [(18)F]FDG-PET and MRI. The aorta was divided into three vascular regions (ascending aorta, aortic arch, and...

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 This study aimed to evaluate the long-term prognostic usefulness of (18)F-FDG PET for patients with metastatic gastroenteropancreatic neuroendocrine tumors (GEPNETs). METHODS Thirty-eight patients with metastatic GEPNETs were prospectively enrolled. Initial check-up comprised CT scan, (111)In-pentetreotide scintigraphy (SRS), and (18)F-FDG PET. Only (18)F-FDG PET-positive lesions w...

Many factors affect standardized uptake values (SUVs) in (18)F-FDG PET/CT. The use of the SUV from a single PET scan in multicenter studies requires the standardization of (18)F-FDG PET/CT procedures. In the context of treatment response assessments (repeated PET scans), many factors may seem to have minor effects on percentage changes in SUVs, provided that imaging procedures are executed in a...

Bone scan is a well-established imaging modality in detection of osseous metastasis. However, its sensitivity decreases at evaluating lytic osseous metastasis in such entity as hepatocellular carcinoma (HCC). Increasingly, Fluorine-18 fluorodeoxyglucose positron emission tomography (18F-FDG PET) with dual-time points imaging is utilized in detection of osseous metastasis from hepatocellular car...

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...
