Medical imaging can often feel overwhelming, especially when terms like “High-Resolution Computed Tomography” are involved. However, understanding what is HRCT thorax test is and how to prepare for it can significantly reduce anxiety and ensure the process goes smoothly. At Semwal Diagnostics, we prioritize patient comfort and clarity.
This guide explains in detail the exact ways of getting ready for your visit, with particular attention paid to the most important issues, such as food intake, dressing, and the time of arrival.
What is a HRCT Thorax Test?
A HRCT thorax test (High-Resolution Computed Tomography) is one of the imaging methods that give doctors a direct view of the lung tissue through the clearest pictures. This advanced scan not only allows doctors to see the lung tissue in detail but also gives very clear thin slices of the lung for better and more accurate diagnosis of interstitial lung diseases, infections, and other complications through high-resolution imaging.
Many patients ask, “Why HRCT thorax test is done?” It is typically recommended when a standard HRCT chest test or X-ray does not provide enough detail to diagnose conditions such as pulmonary fibrosis, bronchiectasis, or to assess lung involvement in systemic diseases.

How to Prepare: A Step-by-Step Guide
Proper preparation ensures that the images captured are clear and that you remain safe throughout the procedure.
1. Eating and Drinking
In the majority of the non-contrast HRCT thorax test cases, there is no need for strict fasting. You can consume a light meal as well as water. Nevertheless, if your certain test necessitates the use of a contrast dye (which is rare for regular HRCT but still a possibility), you may have to refrain from eating for 4 hours before the test.
- General Rule: Hydration is essential.
- Contrast Scans: Four hours prior to the appointment, refrain from eating solid foods if our team has given you such instructions.
2. Clothing and Accessories
The aim is to get rid of any metal that might cause disturbance in the X-ray images.
- Wear: Loose, comfortable clothing. A cotton t-shirt and track pants are ideal.
- Avoid: Clothing with metal zippers, buttons, or underwire bras.
- Remove: Jewelry, glasses, hearing aids, and removable dental work before entering the scanner.
3. Timing and Documents
- Arrival: Please arrive at least 15 minutes before your scheduled time at Semwal Diagnostics to complete necessary paperwork.
- Records: Bring previous X-rays or doctor’s prescriptions to help our radiologists compare findings.
