Classified under:
Nouns denoting acts or actions
Hypernyms ("tomography" is a kind of...):
pictorial representation; picturing (visual representation as by photography or painting)
Domain category:
medical specialty; medicine (the branches of medical science that deal with nonsurgical techniques)
Hyponyms (each of the following is a kind of "tomography"):
X-radiation; X-raying (obtaining images by the use of X rays)
echography; sonography; ultrasonography; ultrasound (using the reflections of high-frequency sound waves to construct an image of a body organ (a sonogram); commonly used to observe fetal growth or study bodily organs)
PET; positron emission tomography (using a computerized radiographic technique to examine the metabolic activity in various tissues (especially in the brain))
magnetic resonance imaging; MRI (the use of nuclear magnetic resonance of protons to produce proton density images)
radiology; radioscopy ((radiology) examination of the inner structure of opaque objects using X rays or other penetrating radiation)
Context examples:
Following exposure to this agent, EGFR expression status can be determined and EGFR overexpressing tumor cells can be visualized using positron emission tomography (PET) imaging.

Visibly abnormal tissue on a magnetic resonance image (MRI) or computed tomography (CT) that does not enhance with contrast and is not edema.
(Non-Contrast Enhancing Tissue, NCI Thesaurus)
A type of computed tomography in which images are taken during the time when the contrast medium has passed the heart and entered the arteries.
(Arterial Phase Spiral CT, NCI Thesaurus)
NMRI makes better images of organs and soft tissue than other scanning techniques, such as computed tomography (CT) or x-ray.
(NMRI, NCI Dictionary)
The latter are measured by means of proton-emission tomography combined with computed tomography (using a radiopharmaceutical known as 18F-Fluorodeoxyglucose).
(Increasing the level of physical activity is found not to improve the functioning of brown adipose tissue, University of Granada)
A type of spiral computed tomography that employs multiple rows of detectors, each capable of producing a simultaneous image (slice).
(Multi-slice Spiral Computed Tomography, NCI Thesaurus)
A type of computed tomography whereby images are taken at certain time points post contrast medium injection.
(Phased Spiral CT, NCI Thesaurus)
The Cu 64 moiety may be detected using positron emission tomography (PET), thereby allowing the imaging and quantification of HER3-expressing tumor cells.
(Copper Cu 64-DOTA-Anti-HER3 Monoclonal Antibody U3-1287, NCI Thesaurus)
Copper Cu 64 trastuzumab binds to the extracellular domain of human epidermal growth factor receptor 2 (HER2), allowing the detection of HER2 distribution using positron emission tomography (PET).
(Copper Cu 64 Trastuzumab, NCI Thesaurus)
A peptide analog of pituitary adenylate cyclase-activating peptide (PACAP) radiolabeled with the positron-emitting radioisotope copper Cu 64, with potential diagnostic ability upon positron emission tomography (PET) imaging.
