Insights

Computed tomography (CT) use in pediatric emergency departments has decreased since 2007. While ultrasound (US) use also declined, the ratio of abdominal US to CT scans increased, indicating a shift in imaging practices for children.

Area of Science:

  • Radiology
  • Pediatric Imaging
  • Medical Imaging Utilization

Background:

  • Concerns regarding radiation exposure from computed tomography (CT) have prompted efforts to reduce its use in pediatric populations.
  • Ongoing research focuses on minimizing radiation dosages in children undergoing medical imaging procedures.

Purpose of the Study:

  • To evaluate long-term trends in the utilization of CT and ultrasound (US) in pediatric emergency departments (PEDs).
  • To analyze changes in the patterns of brain and abdominal CT scans, as well as abdominal US, in pediatric patients over time.

Main Methods:

  • Retrospective analysis of electronic medical data from a tertiary referral hospital's PED (2000-2014).
  • Comparison of CT and US utilization patterns before and after 2007.
  • Statistical analysis of trends in imaging use and the abdominal US/CT ratio.

Main Results:

  • CT utilization in pediatric patients showed a statistically significant decreasing trend after 2007, with exceptions for adolescent abdominal CT.
  • Abdominal ultrasound (US) use also exhibited a decreasing trend.
  • The abdominal US to CT scan ratio significantly increased in the PED, except in the adolescent group.

Conclusions:

  • CT use in pediatric emergency care has declined since 2007.
  • While pediatric US use has also decreased, the increasing abdominal US/CT ratio suggests a shift towards US for abdominal imaging in children, with variations observed in adolescents.

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...

Emerging Adulthood01:27

Emerging Adulthood

Jeffrey Arnett's concept of emerging adulthood offers a framework to understand the unique developmental stage between adolescence and full-fledged adulthood, generally from ages 18 to 25. This period is marked by extensive exploration and shifts in identity, relationships, and career choices, a process known in psychology as role experimentation. Emerging adulthood reflects the evolving cultural expectations surrounding adulthood and the dynamic process of personal transformation during...

Long-term Depression01:05

Long-term Depression

Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTD is the process of synaptic weakening that occurs over time between pre and postsynaptic neuronal connections. The synaptic weakening of LTD works in opposition to synaptic strengthening by long-term potentiation (LTP) and together are the main mechanisms that underlie learning and memory.

Introduction Cardiac Emergencies

Cardiac emergencies are critical situations involving the heart that require immediate medical intervention to prevent severe complications or death. These emergencies often arise from underlying heart conditions that impair the heart's ability to function correctly.Types of Cardiac EmergenciesThe most common types of cardiac emergencies include Acute Coronary Syndrome (ACS), myocardial infarction (MI), cardiac arrest, and heart failure.Acute Coronary Syndrome (ACS)Acute Coronary Syndrome (ACS)...
