18]F-fluorodeoxyglucose uptake thick-walled cavity measuring 40x36 mm, with maximum standardized uptake value
Primary tumor standardized uptake value
(SUVmax) measured on fluorodeoxyglucose positron emission tomography (FDG-PET) is of prognostic value for survival in non-small cell lung cancer (NSCLC): a systematic review and meta-analysis (MA) by the European Lung Cancer Working Party for the IASLC Lung Cancer Staging Project.
PET/CT scans conducted after RFA indicated that 18F-FDG uptake patterns, size of ablation margins and standardized uptake value
were parameters that could predict the likelihood of recurrence.
DWI provides improved conspicuity of lymph nodes, and ADC values for primary cervical malignancy have been correlated with standardized uptake values
(SUVs) for FDG, permitting an additional noninvasive biomarker of disease response.
58% of patients (7 of 12 patients evaluated) reported a greater than 20% decrease in Standardized Uptake Value
(SUV) as measured by positron emission tomography (PET) imaging.
sup] A subsequent study also concluded that [sup]18F-FLT was not as sensitive as [sup]18F-FDG for the diagnosis of NSCLC with [sup]18F-FLT showing 72% sensitivity compared to 89% for [sup]18F-FDG; the standardized uptake value
(SUV) was also much lower for [sup]18F-FLT.
The reconstructed images were converted to standardized uptake value
(SUV) images with patient's body weight and injected dose of FDG.
However, outcomes from two recent trials suggest that FDG-PET imaging can distinguish between patients with indolent and aggressive lymphoma, and that the likelihood of aggressive disease increases in parallel with increases in standardized uptake value
Positron emission tomography-computed tomography (CT) showed diffuse nodules in lung, many of which revealed increased [sup]18 F-deoxyglucose uptake (the average standardized uptake value
Visual assessment and change in maximum standardized uptake value
(SUVmax) were recorded and compared to surgical pathology.
The extent of the SCLC, based on a standardized uptake value
, correlated with clinical course and were 97% sensitive and 78% specific.
Positive [sup]18 F-FDG PET results, especially with a maximum standardized uptake value
of more than 3, in patients with pulmonary amyloidosis should raise suspicion about associated lymphoma or plasmacytoma.
A standardized uptake value
(SUV)--which is the ratio of FDG concentration in the lesion to the average FDG concentration in the body--of >2.
The standardized uptake value
(SUV) quantifies how much of the fluorodeoxyglucose (18) tracer is absorbed by a malignant lesion.
