Repeatability of Standardized Uptake Value in Oncologic 18F-FDG PET
Quantitative analysis can potentially improve the accuracy and consistency of 2-18F-fluoro-2deoxy-D-glucose (18F-FDG) positron emission tomography (PET), particularly for the assessment of tumor response to treatment. Although not without limitations, standardized uptake value (SUV) has emerged as the predominant metric for tumor quantification with 18F-FDG PET. Growing literature suggests that...
متن کاملHepatic 18F-FDG Uptake Measurements on PET/MR: Impact of Volume of Interest Location on Repeatability
Background To investigate same day 18F-FDG (Fluorodeoxyglucose) PET (Positron Emission Tomography)/MR (Magnetic Resonance) test-retest repeatability of Standardized Uptake Value measurements normalized for body weight (SUV) and lean body mass (SUL) in different locations in the liver. Methods This prospective study was IRB approved with written informed consent obtained. 35 patients (20 women...
متن کاملReproducibility of standardized uptake value measurements determined by 18F-FDG PET in malignant tumors.
UNLABELLED 18F-FDG PET is increasingly being used to monitor the early response of malignant tumors to chemotherapy. Understanding the reproducibility of standardized uptake values (SUVs) is an important prerequisite in estimating what constitutes a significant change. METHODS Twenty-six patients were studied on 2 separate occasions (mean interval +/- SD, 3 +/- 2 d; range, 1-5 d). A static PE...
متن کاملRepeatability of metabolically active volume measurements with 18F-FDG and 18F-FLT PET in non-small cell lung cancer.
UNLABELLED In addition to tumor size measurements with CT, there is a need for quantitative measurements of metabolic active volumes, possibly adding to tracer uptake measurements in oncologic response evaluation with PET. The aim of this study was to evaluate the metabolic volume test-retest variability in (18)F-FDG and 3'-deoxy-3'-(18)F-fluorothymidine ((18)F-FLT) PET studies for various comm...
متن کاملLesion-based analysis of 18F-FDG uptake and 111In-Pentetreotide uptake by neuroendocrine tumors
PURPOSE To characterize the heterogeneity of metastatic neuroendocrine tumor (NET) lesions, we compared the [(18)F]-fluorodeoxyglucose (FDG) uptake and the (111)In-pentetreotide (SRS) uptake for somatostatin receptor scintigraphy using the CT-based fusion imaging techniques of PET/CT and SPECT/CT. METHODS Fifteen consecutive patients with NET lesions were examined using both FDG-PET/CT and SR...
