Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

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...

Area of Science:

Dentistry
Biophotonics
Medical Diagnostics

Background:

Conservative dental management necessitates early detection of caries.
Caries initiation causes detectable optical property changes in tooth structure.
Optically based methods leverage these optical changes for caries detection.

Purpose of the Study:

To review the feasibility of three optical technologies for quantitative caries assessment.
To provide an overview of established and developing caries detection methods.

Main Methods:

Quantitative light-induced fluorescence (QLF) for caries research.
Laser-induced fluorescence (LIF) as a clinical tool.
Near-infrared transillumination (NIRT) in developmental stages.

Main Results:

QLF and LIF are established techniques for caries detection and quantification.
NIRT is an emerging technology for assessing enamel caries.
Optical methods offer quantitative or semi-quantitative assessment of caries lesions.

Conclusions:

Optically based methods are valuable for early caries detection and management.
QLF and LIF provide reliable assessment of caries.
NIRT shows potential as a future diagnostic tool for dental caries.
