What Is Angiography?
Angiography is an interventional detection method that injects a contrast agent into a blood vessel. Because X-rays cannot penetrate the imaging agent, angiography uses this feature to diagnose vascular lesions through the image of the imaging agent under X-rays.

- Angiography is an interventional detection method that injects a contrast agent into a blood vessel. Because X-rays cannot penetrate the imaging agent, angiography uses this feature to diagnose vascular lesions through the image of the imaging agent under X-rays.
- Angiography is an auxiliary examination technique. During the development of contemporary technology, angiography is commonly used in the diagnosis and treatment of various clinical diseases, which helps doctors to discover the condition in time, control the progress of the condition, and effectively improve the survival of patients rate. Angiography is an interventional detection method. The contrast agent is injected into the blood vessel. Because X-rays cannot penetrate the contrast agent, the angiography can accurately reflect the location and extent of vascular lesions. But angiography is also a invasive test, and there are many allergic reactions:
- In order for the examination to be performed under the best hygienic conditions, you must be next to the examination bed and put a disinfection sheet on the examination bed. Nurses and doctors must be present during the entire examination. After local anesthesia, a fine needle is inserted into the artery. A guide wire is inserted into a blood vessel through a fine needle. The role of the guide wire is to guide the synthetic catheter to the desired position under exposure. By using a catheter to inject iodine-containing contrast agents, blood vessels in different organs can be displayed. After removing the catheter, the bandage and dressing were used to compress the puncture site to stop bleeding.
- Angiography usually refers to numbers
- With the development of interventional radiology, angiography has become an important clinical diagnostic method, especially in the interventional treatment plays an irreplaceable role. Angiography plays an important role in the diagnosis and treatment of head and neck and central nervous system diseases, cardiac macrovascular diseases, and tumors and peripheral vascular diseases.
