- ‘An ECG, electroencephalogram, electromyogram, and brain computerized axial tomography scan were normal.’
- ‘Another technique that might do for endoscopy what the computerized axial tomography has done for radiology is optical coherence tomography.’
- ‘The most familiar of these is computerized axial tomography (the CAT scan, introduced in the 1970s), which uses x-rays and computers to produce clear cross-section images of body parts.’
- ‘Toward the end of the century, computerized axial tomography and nuclear magnetic resonance tomography were also valuable, particularly when distinguishing between tuberculous and cancerous lesions.’
- ‘A computerized axial tomography scan showed multiple hyperdense lesions in the right and left lobes of the liver.’
- ‘Among the technologies that may be strengthened are radar, computerized axial tomography X-ray scanners, and magnetic resonance imaging systems.’
- ‘Dynamic computerized axial tomography analysis revealed more overinflated units in the left subcarinal slice with pressure-controlled inverse ratio ventilation.’
