Summary
Computed tomography angiography (CTA) rapidly evaluates head and neck vasculature in trauma patients. This noninvasive imaging technique provides excellent detail for identifying vascular lesions and their nature.
Area of Science:
- Radiology
- Vascular Imaging
- Neuroimaging
Background:
- Computed tomography angiography (CTA) is crucial for evaluating head and neck vasculature.
- Patients with acute neurologic symptoms and blunt head/neck trauma require rapid vascular assessment.
Purpose of the Study:
- To review normal head and neck anatomy and variants on CTA.
- To recognize the appearance of vascular pathologies using CTA.
- To describe CTA acquisition parameters and identify common pitfalls.
Main Methods:
- Review of CTA imaging protocols for head and neck vasculature.
- Analysis of CTA findings in patients with acute neurologic symptoms and blunt trauma.
- Correlation of imaging findings with clinical presentation.
Main Results:
- CTA is a noninvasive, rapid imaging modality.
- CTA offers excellent detail in identifying the site and nature of vascular lesions.
- Familiarity with normal anatomy, variants, and pathologies is essential for accurate interpretation.
Conclusions:
- CTA is an effective tool for the emergent evaluation of head and neck vasculature.
- Understanding CTA parameters and potential pitfalls enhances diagnostic accuracy.
- This review aims to improve the interpretation of CTA in acute settings.

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...

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...

The human body's intricate network of arteries ensures that every organ system receives the necessary oxygen and nutrients for optimal function. The arterial network in the head and neck region is particularly complex, providing vital blood flow to the brain, eyes, and other critical structures. Prominent arteries in this region include the internal carotid arteries and the vertebral arteries.
The internal carotid arteries supply blood to the anterior portion of the cerebrum. They enter the...
