DSA Technology

According to the injection of contrast medium into the artery or vein, it is divided into arterial DSA (intraarterialDSA, IADSA) and intravenous DSA (intravenousDSA, IVDSA). Because IADSA vascular imaging is clear and the amount of contrast agent is small, IADSA is used. TeE Imaging Park-Sharing Radiological Medicine Resources.

The operation of DSA is to inject heparin into the catheter after inserting the catheter into the artery to prevent the catheter from clotting. Insert the tip of the catheter into the inspection artery opening, connect the pressure syringe to the end of the catheter, and align the shadow screen at the inspection site before injecting the contrast agent. Before and during the entire imaging process, take pictures for 7-10 seconds at a frame rate of 1 frame per second or more as needed. The IADSA image can be obtained after the console is processed.
