Computed Tomography

9.2K
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...

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...

Area of Science:

  • Pediatric Interventional Radiology
  • Medical Imaging
  • Oncology

Background:

  • Computed-tomography (CT)-guided interventions are valuable for pediatric tumor biopsies.
  • However, concerns exist regarding ionizing radiation exposure in children.
  • This study evaluates radiation dose, accuracy, and speed in pediatric CT-guided interventions.

Purpose of the Study:

  • To analyze the radiation dose associated with CT-guided interventions in pediatric patients.
  • To assess the accuracy and procedural speed of these interventions in a pediatric cohort.
  • To determine the safety and efficacy of CT-guided interventions for pediatric tumor sampling.

Main Methods:

  • Retrospective review of 65 pediatric CT-guided interventions over a 10-year period.
  • Interventions included bone (38), chest (15), and abdomen (12) lesions.
  • Analysis of radiation dose (Dose-Length Product) and procedure duration.

Main Results:

  • All interventions were successfully completed.
  • Mean lesion access path was 6.0 cm; mean procedure time was 25:15 min.
  • Mean Dose-Length Product was 29.5 mGy·cm, with lower doses observed for chest biopsies (p=0.04).

Conclusions:

  • CT-guided interventions in pediatric patients are safe and effective when indicated.
  • Procedures can be performed with both short intervention times and minimal radiation exposure.
  • This technique provides a valuable option for pediatric tumor tissue sampling.
