Computed Tomography01:10

Computed Tomography

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Imaging Studies III: Computed Tomography

DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...

Area of Science:

  • Radiology
  • Medical Imaging
  • Computed Tomography

Background:

  • Multidetector CT scanners are increasingly common in radiology.
  • This has led to a higher demand for 3-D imaging capabilities.
  • Understanding technologist involvement in postprocessing is crucial.

Purpose of the Study:

  • To determine the frequency and types of postprocessing tasks performed by CT technologists.
  • To analyze longitudinal trends in 3-D imaging from 1993 to 2007.
  • To assess the impact of evolving CT technology on technologist roles.

Main Methods:

  • Utilized data from American Registry of Radiologic Technologists (ARRT) CT practice analysis surveys.
  • Analyzed survey responses from 1993, 2001, and 2007.
  • Included a national randomized sample of 1476 full-time CT technologists.

Main Results:

  • Responsibility for 3-D imaging increased significantly, from 47% in 1993 to 82% in 2007.
  • Daily frequency of 3-D imaging tasks rose dramatically, from 4% in 1993 to 53% in 2007.
  • These increases were consistent across all employment settings and department sizes.

Conclusions:

  • Routine 3-D postprocessing is now a typical practice in radiology CT departments.
  • The role of CT technologists in advanced imaging has expanded significantly.
  • Technological advancements have reshaped standard postprocessing procedures.
