Course:
College of Radiographers CPD Endorsed, Radiology - Angiography
Module:
Rotational Angiography and Beyond Using 3D Rotational Angiography
Module Description:
A rotational angiogram can be a quick and easy way to access the anatomy and the surrounding structures with fewer acquisition runs and thus, lower dose. The rotational angiogram can be performed subtracted or non-subtracted depending on the anatomy involved or patient cooperation. Rotational angiography provides the diagnostician with a means of "turning" the vessels so that the vessel of interest can be viewed unobstructed. The addition of 3D-RA to the vascular armamentarium provides another method for evaluation and therapy of complex cerebrovascular processes.
Learning Objectives
* explain the principles of Rotational Angiography (RA)
*identify the applications and the indications and use for RA
*discuss the standard scanning movement
*describe the acquisition technique
*discuss the fundamentals of the procedure
*identify the contrast injection rate/duration vs. the rotation scan time
*explain the basics of three-dimensional rotational angiography (3D-RA)
*discern the uses of 3D-RA in endovascular treatment
