Can positron emission tomography/computed tomography be predictive of diagnostic success in endobronchial biopsies performed through a fiber-optic bronchoscopy in lung cancer?

Annals of Thoracic Medicine, 2018
PURPOSE: The purpose of this study is to investigate the effect of homogeneous/heterogeneous (necrotic) involvement and maximum standardized uptake value (SUVmax) value of the lesion on positron emission tomography-computed tomography (PET-CT) of ...

A better Standard-Uptake-Value Body Habitus Normalizer for Fluorodeoxyglucose in Humans [PDF]

, 2021
Abstract PurposeTo devise a new body-habitus normalizer to be used in the calculation of a standardized uptake value (SUV) that is specific to the PET tracer 18 F-FDG. MethodsAfter exclusions for type and extent of cancer and timing of the scan, a cohort of 481 patients was selected for analysis of 18 F-FDG uptake into “normal” tissues ...

Beneficial implications of adjuvant chemotherapy for stage IB lung adenocarcinoma exhibiting elevated SUVmax in FDG-PET/CT: a retrospective study from a single center

Frontiers in Oncology
BackgroundControversy surrounds the efficacy of adjuvant chemotherapy (ACT) in the treatment of stage I lung adenocarcinoma (LUAD). The objective of this study was to examine the impact of the maximum standardized uptake value (SUVmax) as measured by 18F-

Impact of PET reconstruction protocols on quantification of lesions that fulfil the PERCIST lesion inclusion criteria

EJNMMI Physics, 2018
Background The aim of this study was to compare liver and oncologic lesion standardized uptake values (SUV) obtained through two different reconstruction protocols, GE’s newest clinical lesion detection protocol (Q.Clear) and the EANM Research Ltd (EARL)

Repeatability of brown adipose tissue measurements on FDG PET/CT following a simple cooling procedure for BAT activation [PDF]

, 2019
Brown Adipose Tissue (BAT) is present in a significant number of adult humans and can be activated by exposure to cold. Measurement of active BAT presence, activity, and volume are desirable for determining the efficacy of potential treatments intended ...

Impact of the Definition of Peak Standardized Uptake Value on Quantification of Treatment Response [PDF]

Journal of Nuclear Medicine, 2012
PET-based treatment response assessment typically measures the change in maximum standardized uptake value (SUV(max)), which is adversely affected by noise. Peak SUV (SUV(peak)) has been recommended as a more robust alternative, but its associated region of interest (ROI(peak)) is not uniquely defined.

Prognostic value of pretreatment standardized uptake value of F-18-fluorodeoxyglucose PET in patients with gastric cancer: a meta-analysis

BMC Cancer, 2017
Background F-18- fluorodeoxyglucose Positron emission tomography (18FDG-PET) has been widely used in clinical practice. However, the prognostic value of the pretreatment standardized uptake value (SUV) for patients with gastric cancer remains ...

Texture analysis of aggressive and nonaggressive lung tumor CE CT images [PDF]

, 2008
This paper presents the potential for fractal analysis of time sequence contrast-enhanced (CE) computed tomography (CT) images to differentiate between aggressive and nonaggressive malignant lung tumors (i.e., high and low metabolic tumors).

Catchment-scale Richards equation-based modeling of evapotranspiration via boundary condition switching and root water uptake schemes [PDF]

, 2015
In arid and semiarid climate catchments, where annual evapotranspiration (ET) and rainfall are typically comparable, modeling ET is important for proper assessment of water availability and sustainable land use management. The aim of the present study is

Prognostic value of the standardized uptake value for 18F-fluorodeoxyglucose in patients with stage IIIB melanoma [PDF]

European Journal of Nuclear Medicine and Molecular Imaging, 2012
FDG PET/CT is an excellent tool to detect melanoma metastases and also allows quantification of FDG uptake using standardized uptake value (SUV). The aim of this study was to prospectively investigate the potential prognostic value of SUV for disease-free survival (DFS) and disease-specific survival (DSS) for patients with stage IIIB melanoma.From ...
