Summary
Dual-energy CT (DECT) offers superior head and neck imaging over conventional CT. DECT enhances tissue characterization and pathology differentiation, improving patient management.
Area of Science:
- Radiology
- Medical Imaging
- Oncology
Background:
- Conventional single-energy CT (SECT) has limitations in characterizing head and neck pathologies.
- Dual-energy CT (DECT), or spectral CT, provides advanced imaging capabilities.
- DECT utilizes two distinct energy levels for enhanced image acquisition.
Purpose of the Study:
- To review the diagnostic applications of DECT in head and neck pathologies.
- To highlight DECT's role in evaluating squamous cell carcinoma and other conditions.
- To explore emerging DECT applications in radiomics and AI.
Main Methods:
- Review of DECT applications in head and neck imaging.
- Analysis of DECT-generated virtual monoenergetic images (VMIs) and iodine maps.
- Evaluation of quantitative features like iodine concentration (IC) and spectral Hounsfield unit attenuation curves (SHUAC).
Main Results:
- DECT enhances tissue characterization and reduces artifacts compared to SECT.
- DECT aids in differentiating head and neck pathologies, including SCC, lymph node metastasis, and infections.
- DECT provides valuable data for radiation therapy planning and post-treatment assessment.
Conclusions:
- DECT significantly improves diagnostic accuracy for head and neck pathologies.
- Integrating DECT into clinical practice requires addressing workflow challenges and ensuring radiologist expertise.
- Evolving DECT technology promises to enhance head and neck pathology management.

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...

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...
