Impact 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...
متن کاملRepeatability 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 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 کاملDifferentiation of aggressive and indolent subtypes of uterine sarcoma using maximum standardized uptake value
OBJECTIVE The aim of the study was to elucidate the differential metabolic activities in aggressive and indolent subtypes of uterine sarcomas, which may aid in managing these heterogeneous tumours. METHODS We retrospectively analysed the PET/computed tomography scans of consecutive patients (N=18) diagnosed with uterine sarcoma at our unit. The patients were divided into indolent (N=4) and ag...
متن کامل18F-FDG/18F-FES standardized uptake value ratio determined using PET predicts prognosis in uterine sarcoma
We investigated whether 16α-[18F]-fluoro-17β-estradiol (18F-FES) and 18F-fluoro-deoxyglucose (FDG) uptake measured using positron emission tomography (PET) predicted prognosis in 18 patients with different histological subtypes of uterine sarcoma. Standardized uptake values (SUVs) and 18F-FDG/18F-FES SUV ratios were determined, and their correlations with progression-free (PFS) and overall surv...
