Computed Tomography01:10

Computed Tomography

9.7K
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...

Description
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...

Area of Science:

  • Radiology
  • Trauma Imaging

Background:

  • Polytrauma patients require rapid and comprehensive imaging assessment.
  • Traditional imaging protocols can be time-consuming and may miss critical injuries.

Purpose of the Study:

  • To evaluate a monophasic multidetector computed tomography (MDCT) protocol with a fixed delay for polytrauma patients.
  • To assess the efficacy of a single-scan, fixed-delay venous phase protocol in detecting injuries.

Main Methods:

  • Retrospective study of 2086 polytrauma patients.
  • Utilized a fixed intravenous contrast media protocol (120 mL at 2 mL/s).
  • Single-scan, monophasic venous phase MDCT was performed.

Main Results:

  • The monophasic venous phase successfully detected parenchymal injuries.
  • Ongoing bleedings were localized effectively.
  • The protocol demonstrated easy feasibility and quickness.

Conclusions:

  • A monophasic venous injection protocol is sufficient for whole-body MDCT in polytrauma.
  • This protocol enables comprehensive injury detection in a time-efficient manner.
  • The fixed-delay, single-scan approach is reliable for trauma imaging.
