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 کاملAccuracy of PET for diagnosis of solid pulmonary lesions with 18F-FDG uptake below the standardized uptake value of 2.5.
UNLABELLED Benign and malignant pulmonary lesions usually are differentiated by 18F-FDG PET with a semiquantitative 18F-FDG standardized uptake value (SUV) of 2.5. However, the frequency of malignancies with an SUV of <2.5 is significant, and pulmonary nodules with low 18F-FDG uptake often present diagnostic challenges. METHODS Among 360 consecutive patients who underwent 18F-FDG PET to evalu...
متن کامل18F-FDG PET/CT of advanced gastric carcinoma and association of HER2 expression with standardized uptake value
Objective(s): Expression of HER2 in gastric carcinoma has direct prognostic and therapeutic implications in patient management. The aim of this study is to determine whether a relationship exists between standardized uptake value (SUV) and expression of HER2 in advanced gastric carcinoma. Methods: We analyzed the 18F-FDG PET/CT results of 109 patients that underwent gastrectomy for advanced gas...
متن کاملA Semi-Automated Technique Determining the Liver Standardized Uptake Value Reference for Tumor Delineation in FDG PET-CT
BACKGROUND 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET)-computed tomography (CT) has been an essential modality in oncology. We propose a semi-automated algorithm to objectively determine liver standardized uptake value (SUV), which is used as a threshold for tumor delineation. METHODS A large spherical volume of interest (VOI) was placed manually to roughly enclose the rig...
متن کاملImpact of different standardized uptake value measures on PET-based quantification of treatment response.
UNLABELLED PET-based treatment response studies typically measure the change in the standardized uptake value (SUV) to quantify response. The relative changes of different SUV measures, such as maximum, peak, mean, or total SUVs (SUV(max), SUV(peak), SUV(mean), or SUV(total), respectively), are used across the literature to classify patients into response categories, with quantitative threshold...
