Coronary arteriography serves as a diagnostic tool in detecting obstruction within the coronary arteries. identify the technique using two catheters inserted percutaneously through the femoral artery.

I believe the correct answer for the question is Judkins technique.
This type of technique provides x-ray imaging of the coronary arteries by introducing one catheter into the femoral artery with maneuver it up into the left coronary artery orifice, followed by a second catheter guided up into the right coronary artery, and subsequent injection of a contrast material. 

Idont know but good luck; )
