A threshold method to improve standardized uptake value reproducibility
Nuclear Medicine Communications, 2000Although standardized uptake values (SUV) are widely used to quantify the uptake of 18F-fluorodeoxyglucose (18F-FDG) in tumours, there are systematic differences in the way this index is applied by different investigators. The aims of this study were to compare the effects of using maximum or mean region counts in the calculation of SUV and to ...

Automated 11C-PiB Standardized Uptake Value Ratio
Academic Radiology, 2008Radiotracers such as (11)C-PiB have enabled the in vivo imaging of amyloid-beta plaques in the brain, one of the histopathologic hallmarks of Alzheimer's disease (AD). Standardized uptake value ratio (SUVR) has become the most common normalization for (11)C-PiB as it does not require dynamic scans or blood sampling.

Standardized Uptake Value Ratio-Independent Evaluation of Brain Amyloidosis
Journal of Alzheimer's Disease, 2016The assessment of in vivo18F images targeting amyloid deposition is currently carried on by visual rating with an optional quantification based on standardized uptake value ratio (SUVr) measurements. We target the difficulties of image reading and possible shortcomings of the SUVr methods by validating a new semi-quantitative approach named ELBA.

The objective of this study is to determine the range of SUVmax of 68Ga-DOTATATE in normal organs and tumoral lesions and establish uptake unrelated to NET.One hundred and twenty patients (57 men, 63 women), who underwent (68)Ga-DOTATATE PET/CT imaging in our institution were analyzed.

AbstractIntroductionKlunk et al. recently proposed a means of standardizing quantitation of amyloid burden from positron emission tomography scans to a common Centiloid scale, and we have applied that method to florbetapir.MethodsFlorbetapir and Pittsburgh compound B scans were acquired for 46 mixed clinical presentation subjects within 18 ± 20 days ...

Among clinicians who use positron emission tomography (PET), the standardized uptake value (SUV) is a popular semi-quantitative value that can be easily assessed whenever a PET study is performed under physiological and pathological conditions. It provides an index of regional tracer uptake normalized to the administered dose of tracer.

Evaluation of Standardized Uptake Value to Assess Cerebral Glucose Metabolism
Clinical Nuclear Medicine, 2000When the cerebral metabolic rate of glucose (CMRglc) is to be measured, arterial blood sampling is usually required for fluorine-18 fluorodeoxyglucose (FDG) and positron emission tomography (PET) studies. However, blood sampling is inconvenient because it requires several staff members and is invasive for patients.To assess cerebral glucose metabolism ...

While the evident advantages of absolute metabolic rate determinations cannot be equalled by static image analysis of fluorine-18 fluorodeoxyglucose positron emission tomographic (FDG PET) studies, various algorithms for the normalization of static FDG uptake values have been proposed.

The distribution of FDG uptake in the stomach is variable. Gastritis is one of the causes of elevated FDG uptake. Helicobacter pylori (HP) infection was found in approximately 80% of patients with peptic ulcer and 30% to 60% of symptomatic gastritis. The C-13 urea breath test (UBT) is one of the gold standard tools in diagnosis of HP infection. The aim

The literature-based meta-analysis confirmed that increased standardized uptake value (SUV) of the primary tumor is a poor prognostic factor in patients with head and neck squamous cell carcinoma (HNSCC), which should be further confirmed in a meta-analysis based on individual patient data.Primary tumor SUV, as measured by positron emission tomography (
