Since Rontgen (Wilhelm Conrad Rontgen) discovered X-rays in 1895, shortly after the discovery of X-rays, in medicine, X-rays have been used to examine the human body, disease diagnosis, the formation of diagnostic radiology (diagnostic radiology) of the new disciplines, and laid the foundation of clinical medical imaging (medical imagingology). The foundation of clinical medical imaging (medical imageology) has been laid. Diagnostic radiology is still the main content of clinical medical imaging, the application of universal. 50's to 60's began to apply ultrasound and nuclide scanning for human body examination, the emergence of ultrasonography (ultrasonography, USG) and γ scintigraphy (γ-scintigraphy). 70's and 80's and the emergence of X-ray computed tomography (X-ray computed tomography, X-ray computed tomography, X-ray computed tomography, X-ray computed tomography, X-ray computed tomography, X-ray computed tomography). In the 1970s and 1980s, X-ray computed tomography (X-ray CT or CT), magnetic resonance imaging (MRI), and emission computed tomography (ECT) were introduced, such as single photon emission computed tomography (single-photon emission). New imaging techniques such as single photon emission computed tomography (SPECT) and positron emission emission tomography (PET) have been developed.
In this way, the diagnostic imageology, including X-ray diagnosis, has been developed in only 100 years.
In this way, diagnostic imaging (diagnostic imageology) has been formed in only 100 years, including X-ray diagnosis. Although the imaging principles and methods of various imaging technologies are different, and the diagnostic value and limitations are also different, but all of them are to make the internal structure of the human body and the organs to form an image, so that we can understand the anatomy of the human body and physiological functioning of the condition and pathological changes to achieve the purpose of diagnosis; all of them belong to the scope of the visual diagnosis of the living organ, which is the special diagnostic method. Interventional radiology (radiology), that is, the collection of specimens under image surveillance or on the basis of image diagnosis, treatment of certain diseases, so that diagnostic imaging for the development of clinical medical imaging of a brand new situation. Clinical medical imaging not only expands the scope of human body examination and improves the level of diagnosis, but also allows for the treatment of certain diseases. In this way, it has greatly expanded the work of this discipline and become an important pillar of medical work.
Chinese clinical medical imaging has developed greatly. The professional team is growing, and imaging departments have been built in all medical units. Modern imaging equipment, in addition to conventional diagnostic imaging equipment, USG, Ct, SPECT and even MRI and other advanced equipment has been applied in the larger medical units, and has accumulated a relatively rich experience. There are many kinds of books and journals specialized in clinical medical imaging, which play a positive role in medicine, teaching, scientific research, training of professionals and academic exchanges. As an academic organization, the National Radiological Society and its local chapters strongly promote domestic and international academic exchanges. Imaging equipment, including conventional and advanced equipment, such as CT and MRI equipment, as well as films, developers, fixers and contrast agents. China has been able to design, produce or assemble them on its own.
