Imaging Studies for Cardiovascular System V: CT

248
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...

DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...

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...

Area of Science:

  • Pediatric Radiology
  • Medical Imaging Technology
  • Patient Sedation Management

Background:

  • Sedation is frequently used for pediatric MRI scans to ensure patient cooperation and image quality.
  • High sedation rates increase healthcare costs and potential risks for pediatric patients.
  • Novel, non-pharmacological interventions are needed to reduce sedation utilization in pediatric MRI.

Purpose of the Study:

  • To evaluate the impact of the MRI-am-a-Hero program on sedation utilization for outpatient pediatric MRI studies.
  • To determine the effectiveness of an educational and supportive program in reducing the need for sedation.
  • To assess the program's efficacy across different patient subgroups.

Main Methods:

  • Retrospective evaluation of sedation rates before and after implementation of the MRI-am-a-Hero program.
  • Multivariate regression analysis controlling for patient age, MRI type, case complexity, and contrast use.
  • Subgroup analysis based on age, neurological vs. non-neurological MRI, and contrast administration.

Main Results:

  • Overall sedation utilization decreased from 22.9% to 17.3% post-implementation.
  • The MRI-am-a-Hero program was associated with a 40% reduction in the odds of sedation (OR 0.60, P < .001).
  • The program demonstrated the greatest effect in younger children (ages 4-7, OR 0.56; ages 8-11, OR 0.64).

Conclusions:

  • The MRI-am-a-Hero program is an effective, generalizable, and inexpensive method for reducing sedation in pediatric MRI.
  • The program is particularly beneficial for children aged 4 to 11 years undergoing MRI.
  • This intervention offers a promising alternative to pharmacological sedation for pediatric patients.
