Blood flow analysis (血流解析) is a technology to visualize blood flow by fluid analysis of blood flow based on medical images obtained from MRI, CT and echo, and by calculating various indices such as energy loss. By analyzing blood flow, the technology is expected to be applied to cardiovascular surgery and to predict the prognosis of heart disease. The technology was developed by Keiichi Itatani (板谷慶一), a student at the University of Tokyo's Faculty of Medicine, who attempted to apply fluid dynamics to blood flow. Recent advances in MRI equipment and computer technology have led to rapid advances in blood flow analysis, and it is now possible to analyze data in four dimensions by adding a time axis to the color three-dimensional structure.

Overview
The flow of blood has been studied in the discipline of hemorheology (blood rheology), which has revealed its complex nature. Blood consists of cellular components such as Red blood cells, White blood cells and Platelets, and Plasma, an aqueous solution of various electrolytes and organic substances, and has a non-Newtonian viscosity.

Blood flow analysis involves the numerical analysis of blood flow using computational fluid dynamics (CFD). Techniques have also been developed that apply deep learning to instantly estimate the flow field for vessel geometries constructed from medical images.

Blood flow analysis is also used in research to validate and optimize surgical procedures for congenital heart disease and as a speciality where cardiac surgeons use blood flow analysis to provide surgical treatment for adult congenital heart disease with complex anatomy.

This technology has helped to improve reproducibility in the design of cardiovascular surgery and to predict the prognosis of heart disease, enabling early detection and treatment. Furthermore, it provides important information for determining the causes of diseases such as aortic dissection and developing Medical guidelines for their treatment.

Blood flow analysis is expected to support decision-making in medical practice and improve the accuracy and safety of treatment by providing detailed blood flow information that cannot be obtained through conventional testing and observation.

As blood flow analysis is non-invasive and can simulate blood flow, many attempts are now being made in the field of cardiac surgery to assess blood flow before planning cardiac surgery.
