Body was changed:

Cardiac imaging planes are used to orientate imaging instandard orientations for displaying the heart on cardiac MRIMRICT, SPECT, and PET, similar to those used in echocardiography. ThereThe planes are three main planesdefined in reference to the long axis of the left ventricle, which are centred on ais the line (using body imaging planes) fromthat connects the cardiacventricular apex to the middlecenter of the mitral valve, that is the true long axis of the heart 1,24-6

  • short axis view (corresponding to the echocardiographic parasternal short axis plane)
    • planes perpendicular to truethe long axis at the level of mid left ventricle
  • horizontal long axis plane (fourview (corresponding to the echocardiographic apical 4-chamber viewplane)
    • horizontalplanes parallel to that plane perpendicular to shortcontaining both the long axis and the "horizontal" line drawn at the mid ventricular level between the center of the left ventricle and the transition between the diaphragmatic and free wall of the right ventricle 6
  • vertical long axis plane (two(corresponding to the echocardiographic apical 2-chamber viewplane)
    • vertical plane orthogonalplanes containing the long axis and perpendicular to shortthe horizontal long axis views

FurtherAdditional views includehave also been defined 1,2:

  • left ventricular outflow view (three-chamber view)
    • plane that contains the left ventricular apex, center of the mitral valve, and center of the aortic valve
  • right ventricular outflow view
  • oblique sagittal
    • parallel to aortic axis
