What Technique Creates a Three-Dimensional Dynamic Image of Blood Vessels

Question

What technique creates a three-dimensional dynamic image of blood vessels?
A) digital subtraction angiography
B) magnetic resonance imaging
C) dynamic spatial reconstruction
D) positron emission tomography

Accepted Answer

Digital subtraction angiography is a medical imaging technique that creates a three-dimensional dynamic image of blood vessels by subtracting a baseline image without contrast from images taken after contrast is injected into the bloodstream. This technique provides detailed information about the size, shape, and location of blood vessels, as well as any abnormalities or blockages that may be present. Magnetic resonance imaging, dynamic spatial reconstruction, and positron emission tomography are imaging techniques that do not specifically create a three-dimensional dynamic image of blood vessels.
