China News Service, September 28 (Chen Jing Yao Jun) There are a large number of cardiovascular disease patients in China, and many patients with coronary heart disease have no obvious symptoms before the onset.

Helping patients find heart "hidden dangers" as early as possible and efficiently is a goal that doctors are constantly striving to achieve.

  The reporter learned on the 28th that medical institutions in Shanghai took the lead in exploring the introduction of artificial intelligence AI technology and fully upgraded scanning technology. The overall waiting time for coronary CT was shortened by 90%; the upgrade of scanning technology has greatly reduced the radiation dose received by patients.

  Coronary CT is a non-invasive examination, mainly used for screening and diagnosing coronary heart disease.

It can determine the size and texture of atherosclerotic plaques and the resulting vascular stenosis and blockage, providing an important basis for clinical diagnosis.

Yu Hong suggested that high-risk groups should include coronary CT in routine health screening items.

  The reporter walked into the Chest Hospital of Shanghai Jiaotong University School of Medicine (Shanghai Chest Hospital) that day.

Mr. Xu, who is more than 60 years old, has just completed a coronary CT scan, and his feelings are very different from previous years.

He said frankly: "Before, it was very troublesome to have a coronary CT scan. My heartbeat was relatively fast. Every time I had a checkup, I had to take medicine to control my heartbeat and practice breathing. Sometimes it took a long time to complete the check." But "this time , I just lay there and said, "Wh," the examination will be completed in a few minutes. It is very convenient." Mr. Xu is a patient with "three highs" and has a family history of coronary heart disease. The doctor recommended that he have regular coronary CT scans.

  According to reports, Shanghai Chest Hospital uses artificial intelligence AI technology to multi-dimensionally improve the energy level of coronary CT examinations. While the waiting time of patients has been greatly shortened, the radiation dose has also been reduced by 80%, and the efficiency of coronary heart disease screening has been greatly improved. Lay the foundation for popularization.

  A CT heart scan will get about 300 cross-sectional photos.

Doctors need to carry out three-dimensional three-dimensional reconstruction to form a complete three-dimensional high-definition picture of the heart and coronary arteries.

According to the traditional method, for radiologists, the three-dimensional reconstruction of "coronary CT" is not only mental work, but also physical work.

Yu Hong, director of the Department of Radiology of Shanghai Chest Hospital, told reporters vividly that in the hundreds of photos scanned by coronary CT scans, the images of the cardiovascular blood vessels are scattered like scattered pearls.

In the three-dimensional 3D reconstruction, the doctor is like a "string of beads", the "beads" need to be "finished" from the photos, and then connected in series to reconstruct a heart vessel for diagnosis.

  According to Jiang Yifeng, deputy chief physician of the Department of Radiology of Shanghai Chest Hospital, every person’s heart has nearly 10 such blood vessels. It takes at least 30 minutes for doctors to process a patient’s coronary CT image.

This leads to low efficiency of coronary CT scans and long waiting times for patients.

The public and the doctors are not satisfied.

  The artificial intelligence AI system combined with optimized CT scanning technology, the "smart coronary CT" built in a "two-pronged approach" has changed this medical service dilemma.

Yu Hong revealed that with the "blessing" of the AI ​​system, artificial intelligence can complete the three-dimensional three-dimensional reconstruction of blood vessels in just 5 minutes when processing patient CT images, automatically generate three-dimensional high-definition photos of the cardiovascular blood vessels, and sort out the preliminary diagnosis report.

Since then, the doctors bid farewell to the cumbersome mechanical "bead stringing" operation, and focused more on disease assessment and diagnostic analysis, and the examination report was more detailed, accurate and detailed.

  The hospital revealed that now, when patients come to the hospital for a coronary CT scan, the appointment time has been shortened from one month to 2-3 days. The diagnosis report can be obtained within 48 hours after the examination, and the overall waiting time has been reduced by 90%.

During the interview, the reporter learned that the hospital has fully upgraded its scanning technology, changing the previous "machine gun" sweeping scanning to "sniper gun" precision strikes. The heart "plops" and all scans are completed. The radiation dose has been reduced by 80% and inspections have become safer.

  Statistics disclosed by the hospital show that since May last year, the hospital's "smart coronary CT" has completed nearly 10,000 patient examinations.

Yu Hong suggested: “High-risk groups should include coronary CT in routine health screening programs, regularly'take pictures' of the heart and blood vessels, and cultivate good health awareness and habits of'early screening, early detection, early diagnosis and treatment'." (End) )
