Answer

Imaging modalities that can be employed in the diagnosis and evaluation of PCA strokes include computed tomography (CT) scanning, CT angiography (CTA), single-photon emission CT (SPECT) scanning, magnetic resonance imaging (MRI), and MR angiography (MRA). Positron emission tomography (PET) scanning can be used to analyze neurometabolism in vivo; it is at present a research tool.
