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...

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 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...

CBCT Use in Endodontic Diagnosis.

Dentistry Today

|March 22, 2016

Summary

Cone-beam computed tomography (CBCT) enhances endodontic diagnosis by providing 3-D imaging, but should complement, not replace, 2-D radiographs. Use CBCT judiciously when conventional imaging is insufficient for accurate diagnosis.

Area of Science:

Dentistry
Radiology
Cone-beam computed tomography (CBCT)

Background:

Conventional 2-D radiography is standard for dental evaluations but has diagnostic limitations.
Cone-beam computed tomography (CBCT) offers advanced 3-D imaging capabilities in dentistry.
CBCT aids in resolving complex diagnostic dilemmas and treatment planning challenges.

Observation:

CBCT provides superior insight into dental structures compared to 2-D radiographs.
The diagnostic potential of 2-D radiographs is limited in complex cases.
CBCT allows for detailed 3-D manipulation and analysis of images.

Findings:

CBCT should be used as an adjunct to, not a replacement for, 2-D radiography.
The principle of ALARA (as low as reasonably achievable) must be applied to CBCT radiation exposure.

CBCT is not recommended for routine use without clinical indications necessitating a detailed view.

Implications:

CBCT is justified and highly beneficial when additional information is required for accurate endodontic diagnosis.
Judicious use of CBCT improves diagnostic accuracy and treatment planning in endodontics.
Case examples demonstrate the value of CBCT in managing complex endodontic cases.
