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 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: Kidney, Ureter, and Bladder Studies

Kidney, Ureter, and Bladder (KUB) StudiesKidney, Ureter, and Bladder (KUB) studies are standard diagnostic imaging procedures used to assess the anatomy of the urinary system. They are commonly utilized for patients experiencing abdominal pain or urinary symptoms. By using a simple X-ray of the abdomen, KUB studies can reveal structural and pathological abnormalities within the kidneys, ureters, and bladder. These studies are particularly valuable in diagnosing kidney stones, urinary...
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...

Area of Science:

  • Medical Imaging
  • Radiology
  • Pediatric Imaging

Background:

  • Optimizing radiation dose in pediatric computed tomography (CT) is crucial for balancing diagnostic image quality with patient safety.
  • Current pediatric CT protocols often lack site-specific reference doses, potentially leading to suboptimal radiation exposure.
  • Body width (BW) is a readily available metric for size-specific dose estimation in children.

Purpose of the Study:

  • To establish diagnostic reference ranges (DRRs) for pediatric CT scans of the abdomen and/or pelvis.
  • To develop a method for calculating site-specific reference doses based on body width (BW).

Main Methods:

  • A multicenter retrospective study analyzed 954 CT scans from 939 pediatric patients.
  • Size-specific dose estimate (SSDE) was calculated based on body width (BW), CT dose index, dose-length product, and effective dose.
  • DRRs were developed by reviewing image quality and establishing lower and upper bounds for dose ranges across different BW categories.

Main Results:

  • Diagnostic reference ranges (DRRs) for SSDE were established for pediatric patients across various body width categories (e.g., 5.8-12.0 mGy for BW < 15 cm to 13.1-19.0 mGy for BW ≥ 30 cm).
  • The fraction of adult doses used for pediatric patients increased with body width, ranging from 0.4 for 10 cm BW to 0.9 for 30 cm BW.
  • These findings provide quantitative data for size-specific dose adjustments.

Conclusions:

  • Diagnostic reference ranges (DRRs) help balance radiation risk and diagnostic benefit in pediatric CT.
  • Calculating reference doses as a function of body width offers a practical tool for individual practices.
  • Site-specific CT protocols can be developed to effectively manage pediatric radiation doses.
