Interventional radiology equipment in the vertical projection direction, should try to use the bed balloon.
Interventional Radiology (Interventional Radiology) is a term first proposed by Margulis in 1967. It is a marginalized discipline that developed rapidly in the late 1970s. It is a series of techniques for the diagnosis and treatment of various diseases using catheters, guidewires and other equipment under the guidance of medical imaging equipment, based on diagnostic imaging and clinical diagnostics, combined with the principles of clinical therapy.
The discipline of diagnostic imaging and treatment under the guidance of medical imaging (X-ray, ultrasound, CT, MRI), through percutaneous puncture route or through the body's original orifice, inserting special catheters or instruments into the diseased area. The procedure is performed by a physician or a physician's office, or by a physician's office, or by a physician's office.
Interventional radiology is based on diagnostic imaging, selective or super-selective angiography, fine-needle aspiration and cytopathology and other new technologies. It includes two basic elements: ① based on diagnostic imaging, the use of catheters and other technologies, non-surgical treatment of some diseases under imaging surveillance. ② Under imaging surveillance, the use of percutaneous puncture, catheterization and other techniques to obtain histological, bacteriological, physiological and biochemical data to clarify the nature of the lesion.
It can be understood in this way: interventional radiology is guided by imaging medicine, for modern medical diagnosis and treatment provides a new way of drug delivery and surgical methods. Compared with the traditional way of drug delivery and surgical methods, it is more direct and effective, simpler and minimally invasive.
