Computed Tomography

9.2K
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...

Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

Introduction: MRI and CT scans are crucial advancements in medical imaging techniques, playing a vital role in diagnosing conditions related to the gastrointestinal (GI) system. Each scan serves distinct purposes, targets specific areas, and requires unique nursing duties.
Description of the Procedures
Computed Tomography (CT) scan:
Computed Tomography (CT) scans use X-ray technology to generate detailed images of bones, organs, and tissues. During the scan, the patient lies on a moving table...

Area of Science:

  • Radiology
  • Pediatric Imaging
  • Trauma Imaging

Background:

  • Computed tomography (CT) is crucial for diagnosing pediatric trauma.
  • Optimizing CT protocols is essential for accurate assessment in pediatric patients.
  • The split-bolus technique aims to improve vascular opacification in CT scans.

Purpose of the Study:

  • To evaluate the effectiveness of the split-bolus CT technique.
  • To assess vascular enhancement in pediatric trauma patients.
  • To determine the adequacy of solid-organ injury assessment using this technique.

Main Methods:

  • Retrospective review of split-bolus trauma CT scans in patients under 16 years old.
  • Analysis of abdominal aortic and portal vein attenuation.
  • Assessment of image quality for grading solid-organ injuries.

Main Results:

  • Mean aortic attenuation was 267 HU and mean portal vein attenuation was 203 HU.
  • Five cases of solid-organ injury were detected and adequately assessed.
  • Image quality was sufficient for injury grading and clinical management in all cases.

Conclusions:

  • The split-bolus CT technique achieves good arterial and portal venous enhancement in pediatric trauma.
  • The technique is adequate for assessing solid-organ injuries in this population.
  • Local protocols utilizing this technique are supported, with ongoing audits planned.
