Positron emission tomography (PET) with (18)F-fluorodeoxyglucose ((18)F-FDG), a glucose analog, is widely used throughout the world as an indispensable imaging modality for the management of cancer treatment. This article reviews the pioneering achievements of PET in oncology with a focus on the development of PET that occurred from 1980 through the early-1990s. (18)F-FDG was first applied for ...

UNLABELLED Small-animal PET scanning with (18)F-FDG is increasingly used in murine models of human diseases. However, the impact of dietary conditions, mode of anesthesia, and ambient temperature on the biodistribution of (18)F-FDG in mice has not been systematically studied so far. The aim of this study was to determine how these factors affect assessment of tumor glucose use by (18)F-FDG PET ...

UNLABELLED The metabolic activity of the primary tumor is an important variable in (18)F-FDG PET interpretation for presurgical staging, because this activity is likely to affect the possibility of detection of malignant involvement in lymph nodes (LNs). The purpose of this study was to reevaluate the diagnostic accuracy of (18)F-FDG PET/CT for the presurgical staging of esophageal squamous cel...

UNLABELLED This study aimed to assess the role of a quantitative dynamic PET model in pancreatic cancer as a potential index of tumor aggressiveness and predictor of survival. METHODS Seventy-one patients with (18)F-FDG-avid adenocarcinoma of the pancreas before treatment were recruited, including 27 with localized tumors (11 underwent pancreatectomy, and 16 had localized nonresectable tumors...

UNLABELLED Fine-needle aspiration biopsy (FNAB) is inconclusive in up to 20% of patients with solitary thyroid nodules. In these cases, hemithyroidectomy is necessary, but only 20% of the nodules prove to be thyroid carcinoma. The aim of this study was to explore the potential of (18)F-FDG PET to reduce the number of unnecessary hemithyroidectomies in the preoperative assessment of thyroid nodu...

UNLABELLED The treatment of metastatic neuroendocrine tumors depends on the aggressiveness of the disease. We wanted to know whether (18)F-FDG PET and somatostatin receptor scintigraphy (SRS) can predict early disease progression and patient survival. METHODS We undertook a prospective study of patients with metastatic neuroendocrine tumor diagnosed between September 2003 and January 2006. Af...

UNLABELLED The purpose of this study was to evaluate the effects of pegfilgrastim, a long-acting granulocyte colony-stimulating factor, on the normal biodistribution of (18)F-FDG in an animal model and in humans. METHODS Two groups of 12 rats received a single subcutaneous injection of either normal saline or pegfilgrastim. One, 7, 14, and 21 d after injection, biodistribution studies were pe...

OBJECTIVES (15)O-water-perfusable tissue fraction (PTF) has been shown to be a potential index for assessing myocardial viability in PET, an alternative to (18)F-fluorodeoxyglucose (FDG). This study aimed to directly compare these two independent methods in assessing myocardial viability in patients with abnormal wall motion. METHODS PET study was performed on 16 patients with previous myocar...

introduction:brain imaging with f-18 fluorodeoxyglucose (18f-fdg) positron ‎emission tomography or tc-99m hexamethylpropyleneamine oxime (‎99mtc-hmpao) spect is widely used for the evaluation of alzheimer's ‎dementia (ad); we aim to assess superiority of one method over the ‎other. methods: twenty four patients with clinical diagnosis of alzheimer disease ‎underwent 18f-fdg pet and ‎99mtc-...

UNLABELLED This prospective study aimed to compare the diagnostic performance of (18)F-fluorocholine and (18)F-FDG for detecting and staging hepatocellular carcinoma (HCC) in patients with chronic liver disease and suspected liver nodules. METHODS Whole-body PET/CT was performed in a random order at 10 min after injection of 4 MBq of (18)F-fluorocholine per kilogram and at 1 h after injection...
