Quiz: Cardiovascular: Cardiac Function 4

The key reason that cine imaging is a fundamental part of every CMR study is:

Cine images provide comprehensive tissue characterisation.
Ejection fraction is highly prognostic.
A significant coronary stenosis can be detected using the perfusion information available.
Everyone loves to see their heart beating.

For LV functional analysis, a short axis stack must be planned:

From the AV groove to the apex
From the top of the atria to the apex
On any long axis view
Perpendicular to the LV axis on a 2 chamber and 4 chamber view, but not necessarily perpendicular to the mitral valve.
Parallel to the mitral valve but not necessarily perpendicular to the long axis of the LV.

A key advantage of CMR derived measures of cardiac function over echocardiography derived measures is:

CMR is a much cheaper exam.
CMR images have higher spatial and temporal resolution
CMR derived measures are more reproducible (leading to reduced sample size requirements).
Echocardiography derived measures are more reproducible (leading to reduced sample size requirements).
