What are the development prospects of medical students (especially medical imaging departments) at home and abroad in recent years?

The new situation of medical imaging development is constantly developing.

In the new century, the globalization and sustainable development of knowledge and economy will become the mainstream of human social and economic development. Among them, life science and information science will be the main disciplines for scientific development across the century.

Modern medicine is evidence-based medicine. Medical imaging includes a variety of imaging examinations and treatment methods, and has become the largest source of clinical evidence. It is worth mentioning that the development trend of medical imaging is the integration and optimization of multiple imaging examination methods. In addition, information exchange and mutual integration are also needed within the medical imaging profession.

The development of medical imaging is manifested in several aspects. Image digitization is the basic need for the development of imaging; equipment networking can improve the use and maintenance efficiency of equipment; diagnostic integration can optimize a variety of imaging examinations and improve The accuracy of diagnosis; systematic grouping can be more closely integrated with clinical practice, giving full play to the advantages of comprehensive imaging; and file-free archiving enables digital management.

The necessity of full digital construction of imaging

The digitization of imaging departments is an important part of the digital construction of hospitals. Its main advantages are: it can simplify and precise department management, and provide new A new way of reading digital images; reducing cumbersome file management; fully retaining image data, which is the best guarantee for scientific research, teaching and resolving possible future legal disputes; reducing film usage and saving camera and film processor chemicals.

The digitization of imaging departments is still a need of clinical departments. Imaging information is used clinically. In the process of clinical diagnosis and treatment, it can especially enable departments such as emergency departments and operating rooms that urgently need to see images to quickly obtain imaging data, improve the level of emergency and first aid, significantly speed up medical procedures, and better serve patients. Serve.

In addition, the digitization of imaging departments is also a need for discipline development. The digitization of imaging data is the prerequisite for the sharing of imaging resources and remote consultation. Through digitization, informatization, and networking, hospitals can achieve management work of modernization. In addition, digitization also provides medical staff with a large amount of image data and information that can be used at will, thereby generating greater social and economic benefits.

Digital imaging

Hospital digital construction is the product of the combination of electronic industry, computer technology and medicine. It is the inevitable development of imaging and the development of science as a whole. With the development of science to this day, electronic information and computer technology have been fully developed, and the product of their combination is the origin and foundation of the current development of digital imaging. The main advantages of digital imaging are: it can turn simulated dead images into reusable or data, and further turn two-dimensional flat images into multi-dimensional three-dimensional images; it can make quantitative imaging diagnosis possible; it has completely changed traditional medicine. How images are viewed, used, stored and managed.

Digital imaging turns past analog images into reusable data. In the past, hospitals gave patients an X-ray, which could only record the patient's image under the current conditions and could not see anything new through it. Digitization turns images into a kind of living data, and can turn the two-dimensional flat images in the past into multi-dimensional three-dimensional images. In the past, there was only one plane and length and width into a length, width, height or front, back, left, right, Stereoscopic image from above and below.

Due to the different functions introduced, medical imaging itself not only reflects the three-dimensional structure, but also includes elements such as time and resolution. In a functional variation, we call it a four-dimensional image. In the past, we could only make qualitative judgments, and there was no exact data to make quantitative judgments on patients’ films. Now, with the help of digital imaging, we can make accurate measurements of these. For example, by measuring the CT value of a patient's image, the tissue type of the disease can be clearly determined, and a diagnosis can be made.

Based on the digital platform, with the help of digital images, we can clearly display the entire blood vessel course, and even see the tiny blood vessel branches at the end of the organ, which is helpful for us to explore blood vessel lesions.

Standards for large images and full digitization

The standards for full digitization of images should be as follows: all examination equipment (XR, CT, MRI, DSA, etc.) in the radiology department must be digitized ; All imaging examination methods (BU, NM) that display gross morphological information of human organs and tissues for diagnostic purposes must be digitized; all information related to imaging diagnosis and treatment (applications, reports, etc.) in the hospital must be digitized.

The standard of large imaging mainly consists of modern medical imaging disciplines that include both diagnosis and treatment, including radiation (including XR, CT, MRI, DSA), ultrasound, nuclear medicine and other diagnostic imaging technologies and Interventional treatment techniques. At the same time, system grouping rather than equipment division is implemented within the radiology department. The so-called systematic grouping mainly refers to the systematic division of modern medical imaging according to the setting of clinical disciplines when grouping, so that all data such as radiology, ultrasound, and nuclear medicine can be integrated at the same time, which can also provide better diagnosis for patients. Many basis. This is the big image, so that the entire digital image data can be used mutually.

The significance of fully digital large imaging

The realization of full digitalization in hospitals has laid the foundation for the development of medical imaging, such as image control, viewing mode, diagnosis quality, transmission and archiving, information exchange, and management. Base.

It provides the best and most convenient mode for clinical reference to access images. At the same time, remote consultation solves the problem of medical treatment for people in remote areas and promotes the development of medical imaging teaching and scientific research. In addition, full digitalization has improved the platform of medical imaging, and the combination with biotechnology, genetic engineering and medical bioengineering will accelerate the update of prevention and diagnosis and treatment technologies (PET-CT, MRI-CT).

Big imaging is conducive to the selection optimization and information complementation of various imaging technologies in hospitals, and can achieve a close integration between diagnosis and treatment, which greatly promotes the talent training and discipline development of medical imaging. At the same time, it is also conducive to the application of national-level, multi-level, and high-level comprehensive imaging research projects.

Fully digital large-scale imaging can achieve the effect of 1+1≥2. It is a complete reform of the way medical images are viewed, used, stored and managed.

Digital imaging can completely change the traditional medical imaging perspective. Traditional viewing is usually through fluorescent screens or looking at film, but now we have many methods. With the help of digital imaging, we have new ways of using image data, including storage management methods.

Digital imaging can bring us endless benefits. Digital construction can first meet the needs of the department, simplify the management of the department, reduce the labor intensity of doctors, and retain the original patient data, so that doctors can More precise diagnosis will be of great help to doctors’ scientific research and teaching, and it can also resolve possible legal disputes in the future.

The development of medical imaging has given doctors greater initiative in image review and image quality control. Moreover, it has also led to changes in key models of how doctors work. In the past, doctors looked at patients' CT films one by one. But now, when scanning a patient's images, there are 1,000 images. Tens of thousands of images will be generated in a day. Doctors cannot completely read these films. Now with the help of medical imaging, these films can be post-processed to fuse them into a three-dimensional image, so that doctors can view the three-dimensional image first. Digital imaging lays the foundation for diagnostic quality, image and text control, transmission and archiving, information exchange, and department management. It provides the best and most convenient mode for clinical reference images and solves many difficult and marginal problems.

It must be pointed out that the development of information technology has indeed provided us with great convenience, and also promoted the development of medical imaging, teaching and scientific research. Its combination with biotechnology, genetic engineering and medical engineering, Will accelerate the update of new technologies.

Challenges faced by digital imaging

Due to historical reasons, most hospitals in my country currently have independent departments for radiology, ultrasound and nuclear medicine, and even XR, Both CT and MRI work on their own. Many hospitals are bound by old concepts and have misunderstandings in implementation. They only see the update of medical equipment and ignore the importance of full digitalization of hospital equipment. Therefore, hospitals at all levels should improve their understanding of digital imaging, update their concepts, and actively promote its application in hospitals.
