Computed Tomography (CT)

Computed tomography (CT) systems use a series of X-ray images to create an image volume dataset with slices that can be manipulated on any plane using advanced visualization software. The section includes computed tomography scanners, CT contrast agents, CT angiography (CTA and CCTA), CT perfusion, spectral CT (dual-source CT), and iterative reconstruction dose reduction software.

a) Includes scintigraphy and PET with and without concomitant CT. b) Includes conventional radiography, dual-energy x-ray absorptiometry, fluoroscopy, and radiography performed during radiologic interventions. c) Includes general, cardiothoracic, maxillary, plastic, and orthopedic surgery and neurosurgery. d) Includes allergology, cardiology, geriatrics, general internal medicine, pulmonology, gastroenterology, and rheumatology
