Summary
Computed tomography (CT) use in pediatric emergency departments did not increase overall. However, CT scans for head injuries and seizures decreased, while ultrasound use for abdominal pain rose, reflecting a shift towards non-radiation imaging.
Area of Science:
- Pediatric Emergency Medicine
- Radiology Utilization
- Medical Imaging Trends
Background:
- Computed tomography (CT) is a valuable diagnostic tool in pediatric emergency departments (PEDs).
- Concerns regarding radiation exposure in children have prompted investigations into imaging trends.
- Understanding utilization patterns is crucial for optimizing patient care and safety.
Purpose of the Study:
- To analyze the overall trend of CT utilization in PEDs between 2003 and 2010.
- To examine CT utilization trends based on common pediatric chief complaints.
- To compare CT trends with alternative imaging modalities.
Main Methods:
- Retrospective review of electronic chart records from two tertiary care PEDs.
- Analysis of annual CT utilization rates by anatomic location from 2003 to 2010.
- Linear regression analysis to compare CT trends with alternative imaging for head injury, seizure, and abdominal pain.
Main Results:
- No significant change in overall CT utilization was observed from 2003 to 2010.
- Significant declines in head CT utilization for seizures and head injuries were noted.
- Abdominal ultrasound utilization increased for abdominal pain, while abdominal CT utilization remained unchanged.
Conclusions:
- Overall CT utilization in PEDs did not increase through 2010.
- Decreased CT trends and increased use of non-radiation alternatives were observed when options were available.
- This study suggests a potential decrease in pediatric CT utilization, possibly linked to heightened awareness of radiation risks.

01:10Computed 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...

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...

01:29Positron Emission Tomography
Positron emission tomography (PET) is a medical imaging technique involving radiopharmaceuticals — substances that emit short-lived radiation. Although the first PET scanner was introduced in 1961, it took 15 more years before radiopharmaceuticals were combined with the technique and revolutionized its potential.
One of the main requirements of a PET scan is a positron-emitting radioisotope, which is produced in a cyclotron and then attached to a substance used by the part of the body being...
