Angiography is used to diagnose:
Stenosis, occlusion and dilation.

definition of stenosis
The abnormal narrowing of a blood vessel
3 of 16
Definition of occlusion:
The blockage of a blood vessel.
4 of 16
Definition of dilation.
The abnormal widening of a blood vessel.

What is digital subtraction angiography?
Comparing a pre-contrast image to a post-contrast image and subtracting the common elements; to prevent boney detail from getting in the way of visualising blood vessels.
6 of 16
What is roadmapping?
Software used to assist with passing catheters through blood vessels to avoid branches
7 of 16
What is continuous fluoroscopy?
When the tube emits a continuous flow of x-rays, best image quality but has dose implications.
8 of 16
What is pulsed fluoroscopy?
X-ray is emitted in a series of short pulses. more fps = more continuous image.

Essential guidewire characteristics?
Pushability, Steerability, torque, opacity

Screening Tests?
