Solid pseudopapillary tumors (SPT) are rare, unique pancreatic tumors with benign entity and low malignant potential. Limited information is available in the literature reporting their accumulation of fluorine-18 fluoro deoxyglucose ((18)F-FDG) using positron emission tomography/computed tomography (PET/CT). The aim of this retrospective study was to define t he uptake-accumulation of (18)F-FDG...

BACKGROUND Accurate T-staging is pivotal for predicting prognosis and selecting appropriate therapies for esophageal squamous cell carcinoma (ESCC). The diagnostic performance of fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) for its T-staging is uncertain. We investigated use of FDG PET/CT for preoperative T-staging of patients with ESCC. METHODS Patients ...

BACKGROUND To evaluate the effects of long-acting somatostatin analogue (SSA) therapy on 68Ga-DOTA-octreotate (GaTate) uptake at physiological and metastatic sites in neuroendocrine tumour (NET) patients. METHODS Twenty-one patients who underwent GaTate PET/CT before and after commencement of SSA therapy were reviewed. Maximum standardized uptake values (SUVmax) were measured in normal organs...

BACKGROUND Maximum standardized uptake value (SUVmax) and maximum tumor diameter (MTD) have been shown to reflect survival outcome in diffuse large B cell lymphoma (DLBCL). However, applying these values to primary extranodal DLBCL is difficult because they are separate nosological entities with differences in genetic origin. We therefore decided to evaluate whether SUVmax and MTD on 2-[fluorin...

BACKGROUND Patients with hormone receptor-positive breast cancer typically show favorable survival. However, identifying individuals at high risk of recurrence among these patients is a crucial issue. We tested the hypothesis that [18F]-fluorodeoxyglucose positron emission tomography (FDG-PET) scans can help predict prognosis in patients with hormone receptor-positive breast cancer. METHODS B...

In this study, we aimed to evaluate prognostic value of metabolic and volumetric parameters measured from F fluorodeoxyglucose-positron emission tomography/computed tomography (FDG-PET/CT) in patients with resectable pancreatic cancer.Fifty-one patients with resectable pancreatic cancer who underwent FDG-PET/CT and curative operation were retrospectively enrolled. The maximum standardized uptak...

The aim of the study was to evaluate the usefulness of 18F-FLT PET/CT in the detection and differentiation of gastric cancers (GC). 104 consecutive patients (57 cases of adenocarcinoma tubulare (G2 and G3), 17 cases of mucinous adenocarcinoma, 6 cases of undifferentiated carcinoma, 14 cases of adenocarcinoma partim mucocellulare, and 10 cases of end stage gastric cancer) with newly diagnosed ad...

The clinical significance of pituitary uptake on routine whole body 18F-fluorodeoxyglucose (FDG) positron emission tomography/computer tomography (PET/CT) is not completely characterized. We seek to assess the potential differential diagnosis/underlying etiology of pituitary FDG uptake incidentally identified on routine PET/CT scans. A total of 24,007 PET/CT whole body scans in recent 5 years w...

Programmed cell death-1 (PD-1) and programmed cell death-ligand 1 (PD-L1) have been identified as novel targets of immunotherapy of lung cancer. In present study, we evaluated the metabolic characteristics of lung cancer by using 18 F-fluorodeoxyglucose positron emission tomography/computed tomography (18 F-FDG PET/CT) with regard to PD-L1 protein expression. PD-L1 protein expression was evalua...

Intraductal papillary-mucinous neoplasm (IPMN) of the pancreas presents in various histopathological stages from benign to malignant lesions. The differentiation between benign and malignant IPMN is important in order to determine the treatment of the patients. However, pre-operative differentiation remains difficult. The aim of this study was to assess the utility of 2-[18F] fluoro-2-deoxy-D-g...
