Liver Standardized Uptake Value Corrected for Lean Body Mass at FDG PET/CT

Optimum lean body formulation for correction of standardized uptake value in PET imaging.

UNLABELLED Standardized uptake value (SUV) normalized by lean body mass ([LBM] SUL) is becoming a popular metric for quantitative assessment of clinical PET. Sex-specific quantitative effects of different LBM formulations on liver SUV have not been well studied. METHODS (18)F-FDG PET/CT scans from 1,033 consecutive adult (501 women, 532 men) studies were reviewed. Liver SUV was measured with ...

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...

FDG PETCT in colorectal cancer

Colorectal cancer represents the second most common malignancy worldwide, with approximately one million newly diagnosed cases each year, and is the fourth leading cause of cancer mortality. This article provides an overview of the role of FDG (fluorodeoxyglucose) PET (positron emission tomography) CT (computed tomography) for assessment in patients with colorectal cancer. A summary of key lear...

A 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...
