HRCT (High Resolution Computed Tomography) of the Chest is a specialized imaging technique that provides detailed images of the lungs and surrounding structures. It is commonly used to evaluate various lung conditions such as interstitial lung diseases, lung nodules, lung infections, and pulmonary embolism. During the HRCT of the Chest, a series of thin slices of the chest are taken using a CT scanner. These slices are then reconstructed into detailed images that can help identify and diagnose lung abnormalities. The high resolution of the images allows for better visualization of the lung tissue and provides valuable information to guide treatment decisions.
