Congenital cardiologists at Helen Devos Children's Hospital in the United States successfully combined two common imaging techniques, CT (computed tomography) and 3DTEE (3D transesophageal echocardiography), for the first time. Precise 3D heart model. The researchers pointed out that this conception study also opened the way for combining these techniques with a third tool, magnetic resonance imaging (MRI).

According to the Daily Science website, in recent years, 3D printed heart models have become more common from an emerging technology, and the experimental field is dedicated to improving the level of visualization of cardiac structures and features. CT and MRI are established 3D printed cardiac modeling tools. Joseph Vitukadil, deputy director of the Center for Congenital Heart Diseases at Helen Devos Children's Hospital, and colleagues found that 3DTEE can also be used to construct a 3D printed model of the heart of patients with congenital heart disease. Vitukadil reported their results at the Congenital and Structural Heart Disease Interventions Conference in Frankfurt, Germany (CSI 2015) and demonstrated the feasibility of a 3D printed cardiovascular model based on multiple imaging methods.

According to Vitukadil and colleagues, these three methods have their own advantages, combined to further improve the printing effect: CT can enhance the visualization of the external anatomy of the heart; MRI is inside the heart, including the left and right ventricles or the main heart chamber And better in cardiac muscle tissue; 3DTEE works best on the observation of heart valve structure.

"Mixed 3D printing combines the advantages of two or more imaging methods and is expected to improve the accuracy of diagnostics, interventions, and surgical design." The first author of the paper, Helen Dvorth Children's Hospital, cardiac sound spectrum expert Jordan Gosne "The past 3D printing can only use one imaging method, so it is better to use two methods or more data."

“This is a huge leap forward in the visualization of cardiology and congenital heart disease,” said Vitut Kedil. “This technology is expected to benefit cardiologists and surgeons. This model can improve diagnostic capabilities. Improved intervention and surgical design can help determine whether a cure for a heart condition requires surgery or catheter intervention."

Mobile phone users know that both GPS and wireless networks can accurately locate mobile phones. Similarly, multiple imaging techniques complement each other to make the heart's photos clearer. The idea of ​​hybrid imaging is likely to be applied to the observation of other human organs in the future. A major obstacle to medical surgery will also be eliminated. The doctors stared at the screen, and they were able to see the lungs of the people.
