electron beam tomography

(redirected from Electron-beam computed tomography)

electron beam tomography (EBT),

computed tomography in which the circular motion of the x-ray tube is replaced by rapid electronic positioning of the cathode ray around a circular anode, allowing full scans in tens of milliseconds.
Synonym(s): ultrafast CT

The study evaluated the association between the intake of fruit and vegetables in 2,648 people enrolled in the CARDIA study in 1985 and 1986, at an average age of 25 years, and the presence of coronary artery calcium (CAC), measured with electron-beam computed tomography, 20 years later.

Frequency of SHS exposure at home, at work, and in other places was assessed by questionnaire, and CAC scores were derived based on electron-beam computed tomography. The authors report that self-reported frequent exposure to SHS was associated with subclinical coronary atherosclerosis in this cross-sectional study population.

These tests, done with electron-beam computed tomography (EBCT), measure the amount of calcium in the coronary arteries and calculate a score that is an excellent marker of risk.
Electron-beam computed tomography (EBCT), also known as ultrafast CT, involves using a focused high-energy electron beam and a suite of magnetic electron beam deflectors to rapidly sweep the patient and acquire 3-D data without the need for any moving scanner components.
According to results of electron-beam computed tomography (CT)(*) tests performed on 39 people (ages 7 to 30) with end-stage renal disease, researchers have discovered, among the study participants between ages 20 and 30, a proportionately high incidence (14 out of 16) of vascular calcification compared to results of tests done on a control group of 60 healthy young people (of which only 3 participants showed signs of the calcification.) Among the younger participants in the study (those under 20-years-old), however, there was no evidence of coronary-artery calcification.
The beating heart evaded clear X-ray imaging until scientists at the University of California, San Francisco developed electron-beam computed tomography, or EBCT, in the 1980s.
