Biplane Digital Subtraction Angiography Research Articles

Non-isocentric applications of biplane digital subtraction angiography

Biplane DSA, particularly with the option of non-isocentric positioning of the two imaging chains, further decreases the risk of angiography by obtaining multiple views of the same area or views of two different anatomic areas during a single injection of contrast material. For example, an aortorenal angiogram can be recorded at the same time as an arch aortogram using a single injection of contrast. Similarly an intracranial view can be recorded with the same contrast injection as an arch aortogram or cervical carotid arteriogram.
