The MPR images may be oriented parallel to the long,
short or neutral axis of the heart. A neutral-axis
will generally correspond to one of the 3 orthogonal
patient axes: axial, sagittal or coronal.
Automated contour detection is only possible with
short-axis images, which are used in most instances.
In order to compute all cardiac functional parameters,
volume curves and dynamic thickening information,
sufficient slice levels to cover the heart and time frames
to cover the cardiac cycle must be available. For partial
quantitative evaluation, only images from the End
Diastole and End Systole are required.
Preparation
If you want to use short axis images of the heart there
are different possibilities to create them:
During scanning
You can reconstruct short axis spiral oblique (SPO)
images in different heart phases directly during the
examination.
After scanning
1. If you have saved the raw data of the Cardio scan:
You can reconstruct short axis spiral oblique (SPO)
images in different heart phases by loading the raw
data in the examination card of your Navigator, or
you can also load the raw data in the reconstruction
card of your Wizard (optional) console.
2. After reconstruction of different axial heartphases,
you can reconstruct short axis MPR images on the
3D Card.
Hint
Do not enter any comments on the 2
nd
comment line
which is reserved for labeling of the cardiac phase and
heart rate in beats per minute (bpm).
