Specifically, the team measured the maximum arterial target-to-background ratio (TBR) in the most diseased segment of the carotid artery or aorta, which is a measure of 18 F-fluorodeoxyglucose (FDG) uptake in FDG-positron emission tomography/computed tomography (FDG-PET/CT) scans and correlates with markers of inflammation.

Imaging with a combined positron emission tomography and computed tomography scanner shows good accuracy for diagnosing giant cell arteritis versus the gold-standard temporal artery biopsy.

Patients with either of these antibodies should undergo more aggressive cancer screening with early computerized axial tomography scans, or even positron emission tomography in some cases, to allow discovery of underlying occult malignancy.

Computed tomography (CT) axial image of the lungs at the subcarinal level (a) shows marked stenosis of the left bronchus ( arrow ).

But she acknowledged that not all blood vessels can be assessed using this technique, which is possible with the more expensive and less readily available positron emission tomography (PET) scan.

In addition, modalities such as magnetic resonance imaging or positron emission tomography scans are too expensive to be routinely used as screening tools.
