Imaging Studies III: Computed Tomography

129
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...

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...

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...

Description
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...

Area of Science:

  • Radiology and Imaging
  • Medical Software Analysis
  • Cone Beam Computed Tomography (CBCT)

Background:

  • Variability in upper airway (UAW) analysis software necessitates reproducibility comparisons.
  • Cone beam computed tomography (CBCT) is widely used for UAW assessment.

Purpose of the Study:

  • To compare the reproducibility of Dolphin Imaging and Mimics Research software for UAW segmentation.
  • To assess the agreement between two leading software programs in analyzing UAW parameters.

Main Methods:

  • Fifty adult Class III malocclusion CBCT scans were analyzed.
  • Pharyngeal volume and minimal cross-sectional area (mCSA) were measured twice by two evaluators using both software programs.
  • Intraclass correlation coefficient (ICC) and Bland-Altman analysis were used to assess agreement.

Main Results:

  • Both Dolphin Imaging and Mimics Research demonstrated high intrasoftware and interevaluator agreement (ICC > 0.83).
  • High intersoftware agreement was observed for volume (ICC=0.87) and mCSA (ICC=0.97).
  • Statistically significant differences in mean values were noted between software, but agreement remained clinically acceptable.

Conclusions:

  • Dolphin Imaging and Mimics Research provide highly reproducible results for UAW segmentation.
  • Clinically acceptable agreement exists between Dolphin Imaging and Mimics Research for UAW volume and mCSA analysis.
  • Both software packages are reliable tools for UAW segmentation in CBCT imaging.
