Imaging Studies III: Computed Tomography

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...

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...

Summary

Pediatric pubic symphysis width varies by age and sex, decreasing with skeletal maturity. Males generally have wider symphyses than females, with significant differences observed in older age groups.

Anatomy
Orthopedics

Background:

Defining normal pubic symphysis width in children is challenging.
Pathologic widening requires established reference ranges.

Purpose of the Study:

To establish normal pubic symphyseal widths in pediatric patients.
To stratify ranges by age and gender using CT scans.

Main Methods:

Retrospective analysis of 140 pediatric patients' axial CT scans (ages 2-15).
Measurement of narrowest pubic symphyseal width.
Stratification into age groups (2-5, 6-11, 12-15 years) and by gender.

Main Results:

Mean pubic symphysis width across all subjects was 4.59 mm.
Males (4.86 mm) had wider symphyses than females (4.33 mm).
Width significantly decreased with age, particularly between younger and older groups, and differed between sexes.

Conclusions:

Pediatric males typically have wider pubic symphyses than females.
Pubic symphysis width decreases with age towards skeletal maturity in both sexes.
