2.87 0.82 versus 1.55 0.17; 18F-FDG: 1.58 0.21 versus 1.30 0.13; both P 0.001). 18F-NaF uptake displayed a progressive rise with valve severity (r 0.540, P 0.001), with a more modest increase observed for 18F-FDG (r 0.218, P 0.001). Among patients with aortic stenosis, 91% had increased 18F-NaF uptake ( 1.97), and 35% had increased 18F-FDG uptake ( 1.63). A weak correlation between the activities of these tracers was observed (r 0.174,

Systemic atherosclerotic plaque vulnerability in patients with Coronary Artery Disease with a single Whole Body [FDG]PET-CT scan
Objective(s): Cardiovascular disease is a leading cause of morbimortality with over half cardiovascular events occurring in the asymptomatic population by traditional risk stratification. This preliminary study aimed to evaluate systemic plaque vulnerability in patients with prior Coronary Artery Disease (CAD) with a single Whole Body [FDG] PET-CT scan in terms of plaq...

متن کاملThe effect of fasting on Positron Emission Tomography (PET) imaging
As a nuclear approach, Positron Emission Tomography (PET) is a functional imaging technique which is based on the detection of gamma ray pairs emitted by a positron-emitting radionuclide. There are certain limitations to this technique such as normal tissue uptake. Therefore, it has been recommended that patients prepare before scanning. Fasting for a short while before PET imaging is an exampl...
متن کاملUpdate on cardiac imaging techniques 2013.
Cardiac imaging is a cornerstone of diagnosis in heart conditions, and an essential tool for assessing prognosis and establishing treatment decisions. This year, echocardiography stands out as a guide in interventional procedures and in choosing the size of the prosthesis. It is also proving to be a valuable technique in low-flow, low-gradient aortic stenosis. Three-dimensional echocardiography...
