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...

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 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...

Positron Emission Tomography

Positron Emission Tomography

Positron emission tomography (PET) is a medical imaging technique involving radiopharmaceuticals — substances that emit short-lived radiation. Although the first PET scanner was introduced in 1961, it took 15 more years before radiopharmaceuticals were combined with the technique and revolutionized its potential.
One of the main requirements of a PET scan is a positron-emitting radioisotope, which is produced in a cyclotron and then attached to a substance used by the part of the body being...

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 Biological Samples with Optical Microscopy

Imaging Biological Samples with Optical Microscopy

Optical microscopy uses optic principles to provide detailed images of samples. Antonie van Leeuwenhoek designed the first compound optical microscope in the 17th century to visualize blood cells, bacteria, and yeast cells. In 1830, Joseph Jackson Lister created an essentially modern light microscope. The 20th century saw the development of microscopes with enhanced magnification and resolution.
In optical microscopy, the specimen to be viewed is placed on a glass slide and clipped on the stage...

Summary

Optical coherence tomography (OCT) provides noninvasive "optical biopsies" of oral tissues. This imaging method aids in early detection and monitoring of various dental and mucosal diseases without ionizing radiation.

Area of Science:

Biomedical optics
Dental imaging
Oral diagnostics

Background:

Optical coherence tomography (OCT) is a noninvasive imaging technique.
It provides microstructural detail of oral tissues in situ.
OCT offers quantitative and qualitative diagnostic information.

Purpose of the Study:

To highlight the capabilities of OCT in oral diagnostics.
To demonstrate OCT's potential for early disease detection.
To showcase OCT as an alternative to ionizing radiation-based imaging.

Main Methods:

Utilizing OCT for cross-sectional imaging of oral tissues up to 3 mm depth.
Achieving axial resolution of 1-10 micrometers.
Real-time monitoring of tissue on a computer monitor.

Main Results:

OCT provides high-resolution imaging of hard and soft oral tissues.
It captures microstructural details beyond the capabilities of X-rays.
Potential for detecting early-stage oral diseases and conditions.

Conclusions:

OCT serves as a valuable noninvasive tool for oral health assessment.
It enables early diagnosis and monitoring of dental caries, periodontal disease, and mucosal lesions.
OCT imaging facilitates real-time, radiation-free evaluation of oral tissues.
