X-ray is an indispensable diagnostic imaging technique, currently there are two popular types: CR (traditional) and DR (digital). So what is the difference and which technology should you choose?
CR X-ray: Uses X-ray film to record images, then develops the film with chemicals. The advantage is low initial investment cost, technology familiar to many technicians. However, the big disadvantage is limited image quality, low resolution and contrast, difficult to observe details. The film development process takes time, uses toxic chemicals, bulky film storage, difficult to retrieve.
DR X-ray: Uses a digital sensor (detector) to record images and convert directly into digital signals, displayed immediately on the computer screen. DR images have superior quality, high resolution, rich details, supporting more accurate diagnosis, especially in complex pathological cases. DR also helps shorten diagnosis time, is environmentally friendly (no film, chemicals), easy to store, retrieve and share data. However, the initial investment cost for DR systems is higher than CR.
Optimal choice:
• CR: Suitable for medical facilities with limited budgets, mainly performing basic X-ray techniques.
• DR: Optimal choice for facilities that want to improve diagnostic quality, work efficiency, shorten waiting time for patients and develop sustainably. DR brings long-term benefits in operating costs, work efficiency and service quality.
Conclusion: Although CR X-rays are still in use, DR is gradually replacing and becoming the gold standard in diagnostic imaging. Carefully consider the needs, budget, installation space and development goals of the medical facility to make the right investment decision.
