 Context examples 

Also called computed tomography angiography and CTA.

(CT angiography, NCI Dictionary)

A radioactive form of carbon that is used in positron emission tomography (PET) scanning.

(Carbon-11 acetate, NCI Dictionary)

MRI makes better images of organs and soft tissue than other scanning techniques, such as computed tomography (CT) or x-ray.

(MRI, NCI Dictionary)

As the proliferation of cancer cells is much higher than normal cells, tumor cells exhibit an increased rate of C-11 choline uptake and incorporation, allowing tunor imaging with positron emission tomography (PET).

(Carbon C 11 Choline, NCI Thesaurus)

Although the mechanism is unclear, carbon-11 acetate preferentially accumulates in tumor tissue, serving as a tracer for imaging tumors with positron emission tomography (PET).

(Carbon-11 acetate, NCI Thesaurus)

Computed tomography angiography may be used to check for aneurysms (a bulge in the blood vessel wall), blockages in the arteries, blood clots, and other blood vessel problems.

(Computed tomography angiography, NCI Dictionary)

A radiopharmaceutical composed of the nonspecific perfusion agent ethylglyoxal bis(thiosemicarbazone) (ETS) linked to the beta-emitting, radioisotope copper Cu 62, with potential tumor imaging activity upon positron emitting tomography (PET).

(Copper Cu 62 Ethylglyoxal Bis(thiosemicarbazone), NCI Thesaurus)

The relationship between various air pollutants and emphysema was measured through computed tomography (CT) lung imaging and lung function testing.

(Study finds link between long-term exposure to air pollution and emphysema, National Institutes of Health)

A radiopharmaceutical containing an analogue of tryptophan, alpha-methyltryptophan (AMT), labeled with carbon 11 (11C), used to measure serotonin synthesis in the human brain using positron emission tomography (PET).

(Carbon C 11 Alpha-methyltryptophan, NCI Thesaurus)
