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...

Radiological Investigation I: X-ray and CT

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

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...

Area of Science:

Medical Imaging
Radiology
Radiation Dose Optimization

Background:

Multidetector CT (MDCT) scanning is widely used in clinical practice.
Optimizing radiation dose in CT is crucial for patient safety and effective healthcare.
Standardized data collection and training methods are needed to improve dose management.

Purpose of the Study:

To collect radiation dose data from MDCT in Queensland, Australia.
To evaluate the effectiveness of audit feedback and small-group teaching for dose optimization.
To identify key factors influencing radiation dose in CT procedures.

Main Methods:

Data collection from 10 radiology practices for adult and pediatric CT protocols.
Implementation of a one-day feedback and optimization training workshop.
Comparison of pre- and post-training dose data, including phantom studies.

Main Results:

Significant mean effective dose reductions achieved for adult CT scans: 46% (brain), 28% (pulmonary angiography), 29% (lumbar spine), and 24% (urography).
Substantial phantom dose reductions demonstrated across all participating sites.
Challenges encountered in collecting pediatric data due to low patient numbers.

Conclusions:

Audit feedback and small-group optimization training effectively reduce radiation doses in common adult CT scans.
Access to medical physicists, data collection support, and technologist assistance are critical for successful dose reduction programs.
Further research is needed to address pediatric CT dose optimization.
