Interventional medicine, is based on diagnostic imaging, under the guidance and monitoring of medical imaging equipment, the use of puncture needles, catheters, balloons, stents and other interventional equipment, through the body’s natural orifices or tiny incisions will be specific instruments into the body lesions for diagnosis or minimally invasive treatment, which can not only reverse the dilemma of the internal medicine on the change of the tissue structure of the impotence of the dilemma, but also to avoid surgical procedures on the body of “broad-brush” injury. Surgery on the body can be avoided “drastic” injury. It is very small damage to the human body, can play the therapeutic effect is very reliable, so, interventional medicine has become the third major clinical disciplines after internal medicine, surgery.
The medical imaging equipment commonly used in interventional medicine are digital subtraction angiography machine and dynamic flat panel medium C-arm, so what is the difference between these two equipment?
Digital subtraction angiography (Digital subtraction angiography, DSA), generally consists of X-ray generating device, digital imaging system, mechanical system, computer control system, image processing system and auxiliary system, etc. DSA is an angiographic method of computer-aided imaging. It is the application of computer programs for the completion of the two imaging, before injecting the contrast agent, the first time the first imaging, and the computer will be converted into a digital signal image stored, injected into the contrast agent again imaging and converted into a digital signal, the two digital subtraction, the elimination of the same signal, to get a only the contrast agent of the blood vessel image, the image than the conventional angiographic agent used in the past to display images This image is much clearer and more intuitive than the conventional angiography used in the past, and some of the finer vascular structures can also be shown.
Simply put, a contrast agent is injected into the blood vessel to be examined to reveal the original shape of the blood vessel. Then through the system processing, the blood vessels are displayed more clearly, which is convenient for doctors to diagnose or carry out surgery, and this is why DSA is called “vascular machine”.DSA has a wide range of clinical use, applicable to heart, brain, peripheral and various parts of the vasculature, tumors, urology, respiratory tract, and other gastrointestinal tract and other departments including clinical diagnosis and minimally invasive interventional therapy. It is suitable for clinical diagnosis and minimally invasive interventional therapy.
Dynamic flat panel C-arm compared to the general small C-arm, not only is the balloon power increased, dynamic flat panel C-arm product design of the systematic and maneuverability is to carry out complex interventional procedures is a strong guarantee, increased DSA-related functions. For example, the PLX7100A can be used in orthopedics, hepatobiliary and pancreatic surgery, gastroenterology, in addition to cardiac and cerebral interventions, non-vascular parts of the perfusion embolization, balloon angioplasty, stenting, a variety of parts of the puncture, biopsy, drainage and so on, for example, percutaneous percutaneous biliary drainage, peritoneal drainage, fluoroscopic foreign body removal, biliary stent implantation, digestive stent implantation, and so on. Implantation of biliary stent, gastrointestinal stent, etc.
The C-arm in Dynamic flat panel has its own unique advantages over the high running cost DSA for interventional clinical use. It is more flexible and can be used in digestive, oncology, gynecology, urology, peripheral and other specialized departments. Hospitals do not need to do power electric transformation, general laminar flow operating room environmental conditions can meet the installation and use of the requirements. Moreover, with the rapid popularization of interventional technology and the promotion of the national hierarchical diagnosis and treatment system, the C-arm in the dynamic flat panel has the advantages of appropriate power, high cost-effectiveness, and reduction of the operator’s radiation exposure. As a green and safe interventional diagnostic and therapeutic equipment, it can be said to be the ideal choice of interventional equipment for primary general hospitals.
