Objective:
The purpose of this article is to review the techniques, clinically relevant potential applications, and limitations of xenon-enhanced dual-energy CT of the chest.
Conclusion:
The functional evaluation of lung ventilation may be of great importance to patients with pulmonary disease. Many measures are used to assess pulmonary function, but the results are estimates of only global status rather than the regional distribution of disease. With the introduction of dual-energy CT, regional lung ventilation function can be assessed with inhaled xenon gas. This technique yields not only high-spatial-resolution anatomic information but also information about regional ventilation.

Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
