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...

Area of Science:

Cardiovascular Imaging
Diagnostic Radiology
Vascular Medicine

Background:

Aortic pathologies present with diverse and often non-specific symptoms.
Accurate diagnosis and management rely heavily on non-invasive imaging techniques.
Common imaging modalities include ultrasound, CT, and MRI.

Purpose of the Study:

To review the role of non-invasive imaging in diagnosing and managing aortic pathologies.
To highlight the advantages of computed tomography angiography (CTA) in this context.

Main Methods:

Review of current literature on aortic pathology imaging.
Emphasis on the technical aspects and clinical utility of CTA.
Comparison of CTA with other imaging modalities like ultrasound and MRI.

Main Results:

Computed tomography angiography (CTA) offers excellent anatomical detail and rapid acquisition.
CTA is widely available and has established protocols and indications.
CTA is considered a first-line imaging modality for aortic pathologies.

Conclusions:

Non-invasive imaging is crucial for the comprehensive management of aortic diseases.
CTA is a highly effective and preferred modality for evaluating aortic pathologies.
The capabilities of CTA support screening, diagnosis, treatment planning, and surveillance.
