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...

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...

Imaging Studies for Cardiovascular System V: CT

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: CT and MRI

Imaging Studies I: CT and MRI

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...

Summary

Lower milliampere settings in cone-beam computed tomography (CBCT) scans improve diagnostic image quality. While filter and kilovolt (peak) settings had minimal impact, milliampere variations significantly affected image quality across different fields of view.

Radiology
Medical Imaging
Dental Imaging

Background:

Cone-beam computed tomography (CBCT) is crucial for dental and maxillofacial imaging.
Optimizing CBCT settings is essential for achieving high diagnostic image quality.
Understanding the impact of various parameters on image quality is vital for clinical application.

Purpose of the Study:

To evaluate the impact of different cone-beam computed tomography (CBCT) settings on image quality.
To determine the optimal field of view (FOV) for diagnostic accuracy.
To assess the influence of milliampere (mA), kilovolt (peak) (kVp), and filter usage on image quality.

Main Methods:

A modified Hitachi CB MercuRay unit was used with varying mA (2-15), kVp (100-120), and filter (copper) settings.
Scans were performed on a cadaver head and dry skull across three fields of view (6, 9, 12 inches).
Image quality was assessed by over 30 judges, with diagnostic quality evaluated via questionnaire and statistical analysis.

Main Results:

Higher diagnostic image quality was achieved with 9-inch and 12-inch fields of view (99% diagnostic yield).
Lower milliampere (mA) settings demonstrated significant improvements in image quality, particularly in smaller fields of view.
The presence or absence of a copper filter and kilovolt (peak) settings showed no significant impact on overall image quality.

Conclusions:

Lower milliampere settings are recommended for achieving good diagnostic quality in CBCT imaging.
Field of view significantly impacts diagnostic image quality, with larger FOVs yielding superior results.
Filter and kilovolt (peak) settings are less critical for overall diagnostic image quality compared to mA and FOV.
