Computed Tomography

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...

Radiological Investigation I: X-ray and CT

Radiological investigations, including X-rays and computed tomography (CT) scans, are critical for diagnosing and evaluating various medical conditions. These imaging techniques provide valuable insights into the body's internal structures, aiding in the detection of abnormalities, assessment of disease progression, and development of treatment strategies. This article delves into two primary radiological investigations, chest X-rays and CT scans, outlining their purpose, procedures, and the...

Imaging Studies for Cardiovascular System V: CT

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...

Imaging Studies I: CT and MRI

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...

Imaging Studies for Cardiovascular System III: X-Ray

Imaging Studies for Cardiovascular System III: X-Ray

The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

Summary

Computed tomography (CT) use has grown significantly, but paediatric CT imaging rates in Australia are slowing overall. Some younger age groups even show declining CT scan rates, contrary to adult trends.

Background:

Computed tomography (CT) is a vital diagnostic tool but a major source of population radiation exposure.
Children face higher risks from radiation exposure compared to adults.
Understanding paediatric CT trends is crucial for managing radiation risks in this vulnerable population.

Purpose of the Study:

To assess the impact of paediatric CT in Australia by analysing imaging trends.
To evaluate the trends in CT imaging for children aged 0-18 years.
To compare Medicare data with dedicated paediatric hospital data for accuracy.

Main Methods:

Utilised Medicare data to derive CT imaging trends across Australia.
Analysed data from a dedicated paediatric hospital (Royal Children's Hospital Melbourne) for validation.
Combined datasets to establish comprehensive paediatric CT imaging rates over 20 years.

Main Results:

Overall annual growth in CT services was 8.5% (vs. 1.4% population growth).
Medicare data captured only one-third of paediatric CT imaging.
Paediatric CT imaging rate increased by 5.1% annually over 20 years, but growth has slowed recently, with declines in some younger age groups.

Conclusions:

Increased demand from the adult demographic drives overall CT service growth.
Paediatric CT imaging rate increases have slowed, with some age groups experiencing a decline.
This trend suggests a need to monitor and potentially mitigate radiation exposure in children.
