Telemedicine is becoming a key trend in the development of modern healthcare. On December 19th, Academician Liu Yuqing from the Chinese Academy of Engineering, a pioneer in cardiovascular imaging in China, was invited to Tencent. He shared insights on the historical progress and future direction of medical imaging in China. According to him, radiology and imaging will play an increasingly important role in the future of medicine.
The evolution of medical imaging can be divided into three main stages. Since the discovery of X-rays by German physicist Wilhelm Roentgen in 1895, the field has seen rapid development. The first stage involved the clinical use of X-rays, which gradually evolved into X-ray diagnosis and treatment. This marked the beginning of radiology as a distinct medical specialty.
The second phase saw the expansion of radiology, with more advanced techniques such as angiography being introduced. Procedures like gastrointestinal and cardiac angiography became essential for diagnosing and planning treatments, especially for complex conditions like coronary artery disease. These developments laid the foundation for interventional procedures and improved patient outcomes.
The third stage brought about the integration of various imaging technologies beyond traditional X-rays. In the 1970s, the introduction of CT scans revolutionized the field, followed by the emergence of MRI, ultrasound, and nuclear medicine. These modalities expanded diagnostic capabilities and enabled minimally invasive treatments. By the late 1970s, interventional radiology emerged as a powerful tool, combining both diagnosis and therapy.
In China, the adoption of these advanced imaging technologies lagged behind international standards by about a decade. While developed regions and top-tier hospitals have made significant progress, many grassroots facilities still face challenges in access and equipment. However, the rise of telemedicine and digital imaging has started to bridge this gap, allowing remote consultations and diagnoses through digital transmission.
Despite progress, there are still gaps in basic research and equipment production. Over 90% of high-end imaging devices in major Chinese hospitals are imported, while lower-level facilities often lack even basic tools. This highlights the need for investment in domestic technology and training to close the divide.
Moreover, the application of imaging in clinical settings varies significantly across regions. Tertiary hospitals have advanced capabilities, but rural and underdeveloped areas still struggle with limited resources. Improving the overall quality of medical professionals and standardizing practices remain critical challenges for the future.
Finally, the therapeutic applications of modern imaging continue to grow, especially in fields like cardiovascular imaging. Techniques such as molecular imaging and cellular-level diagnostics are being explored to enhance precision and effectiveness. As the field evolves, it's clear that imaging will remain at the forefront of medical innovation and patient care.
