HRCT uses thinner slices to capture high-resolution images of the lungs, providing more detailed views of lung tissue. This makes it particularly useful for detecting early-stage disease and subtle abnormalities that might be missed on standard CT scans.

No, the HRCT scan itself is painless. The patient will be asked to lie still on a table while the scanner takes images, and they may be asked to hold their breath briefly for clearer pictures.

The scan typically takes around 10 to 15 minutes, depending on the complexity of the imaging and the patient's condition.

HRCT uses a higher dose of radiation compared to standard X-rays. However, the benefits of a detailed diagnosis typically outweigh the risks, especially when used to detect serious lung conditions. Pregnant women and individuals with specific health conditions should inform their doctor before undergoing the scan.
