[Paying attention to the clinical application of radiomics].

Since the concept of radiomics was proposed, both domestic and foreign scholars have successively carried out many scientific researches on radiomics. Domestic and foreign research teams and their corresponding research have achieved certain results in radiomics, but we still face many challenges on the clinical application of radiomics-based models. Currently radiomics is still facing challenges. We should certainly pay attention to the research hotspots, existing problems, and future perspectives of radiomics.

[Promoting the application of federated learning in medical imaging artificial intelligence].

Medical image-based artificial intelligence (AI) systems have shown great potential in assisting disease diagnosis and treatment. However, the challenges, such as data silos, privacy security and standardization, seriously impedes the application of AI in disease diagnosis and treatment. By integrating federated learning technology and FAIR data principle, it is possible to resolve the aforementioned obstacles. Then, it is able to maximize the value of multicenter data to develop a more efficient and accurate disease diagnosis and treatment AI systems, and promote the clinical application of medical image-based AI systems in the field of disease diagnosis and treatment.

Relationship between left ventricular end-diastolic compliance and abnormal Doppler mitral filling in patients with coronary artery disease.

Left ventricular end-diastolic compliance (LVEDC) and transmitral flow velocities were measured in 19 patients with coronary artery disease associated with hypertension and 10 normal subjects by LV catheterization and pulsed-Doppler echocardiography. LVEDC was much lower in the patient than in the normal subjects (P less than 0.01). The data showed that abnormal Doppler diastolic function such as elevated late diastolic peak flow velocity (PVA) and decreased LVEDC occurred in the patients at the same time. In addition, the negative correlation of PVA with LVEDC observed in normal controls but not in patients suggested that in patients with impaired diastolic filling, factors other than the decreased LVEDC itself must also participate in the development of diastolic dysfunction.
