Radiomics and Deep Learning in Clinical Imaging: What Should We Do?
This and next issues of our journal deal with several review articles related to the radiomics and DL in clinical imaging, mainly focusing on cancer imaging. These may be helpful to understand the concept and current status of radiomics and DL in clinical imaging. Due to the recent progress of DL, there is a belief that nuclear medicine physician or radiologist will be replaced by the AI. For instance, the number of applicants for residency in nuclear medicine or radiology was much decreased last year in Korea. Although it is difficult to predict the future medical situation, it may be inevitable that simple diagnostic tasks are replaced by the AI system. That means that the role of nuclear medicine physician and radiologist will be changed, and the understanding and dealing with the DL and AI may be become essential for the nuclear medicine physician and radiologist in the future. For example, as several experts expected, the key role of nuclear medicine physician may become the integration and translation of clinical and imaging biomarkers automatically derived from imaging data by the radiomics and DL methods, and its application to clinical decision making.
In these aspects, what should we do? First, the most important thing is the persistent interest in the radiomics and DL of our society focusing on the research and education. We, ourselves, should be an expert in the radiomics and DL of molecular imaging. We should do the active role for the proper clinical adoption of them. Second, the radiomics and DL should be included in the nuclear medicine residency training program. In the near future, a nuclear medicine physician who cannot do the AI and DL may not survive. Finally, we should have an interest and actively participate in the changes in the laws and healthcare system related to the AI and DL in the medical field. We can contribute to solve the ethical, regulatory, and legal issues raised in the development and clinical application of AI. Also, we should find an appropriate role of nuclear medicine physician in the era of AI.
