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...

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

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...

X-ray Imaging

X-ray Imaging

German physicist Wilhelm Röntgen (1845–1923) was experimenting with electrical current when he discovered that a mysterious and invisible "ray" would pass through his flesh but leave an outline of his bones on a screen coated with a metal compound. In 1895, Röntgen made the first durable record of the internal parts of a living human: an "X-ray" image (as it came to be called) of his wife’s hand. Scientists worldwide quickly began their own experiments with X-rays, and by 1900, X-ray was widely...

Summary

This summary is machine-generated.

Fractal analysis and bone area measurements from cone beam computed tomography (CBCT) scans show potential for assessing bone quality. Density measurements from CBCT were not found to be a valid indicator of bone quality.

Area of Science:

Dental imaging
Biomedical engineering
Radiology

Background:

Assessing bone quality is crucial for diagnosing conditions like osteoporosis.
Dual energy X-ray absorptiometry (DXA) is a standard method for bone mineral density (BMD) measurement.
Cone beam computed tomography (CBCT) is increasingly used in dentistry, offering potential for bone quality assessment.

Purpose of the Study:

To evaluate the accuracy of fractal analysis and morphometry using CBCT for bone quality assessment.
To compare CBCT-derived measurements with DXA-measured bone mineral density (BMD).

Main Methods:

Nineteen mandibular bone samples were processed to simulate osteoporosis or used as controls.
CBCT and DXA scans were performed before and after sample processing.
Fractal dimension (FD), bone area, and density were calculated from CBCT images; BMD was measured using DXA.

Main Results:

A significant positive correlation was found between FD and BMD (rho=+0.71 to +0.75, P<0.05).
Bone area measurements from CBCT also showed a significant correlation with BMD (rho=+0.69 to +0.85, P<0.05).
CBCT-derived bone density analysis did not show a significant correlation with BMD.

Conclusions:

Fractal analysis and bone area measurement using CBCT show promise for evaluating bone quality.
CBCT-derived bone density measurements are not considered valid for bone quality assessment in this study.
These findings suggest CBCT-based imaging analysis could supplement traditional methods for bone quality evaluation.
