Thorax
Hints
• In addition to the mediastinum and the lungs, it may
be necessary to evaluate the axillary fatty tissue and
the bilateral mammary glands. A third reconstruction
can be set up with a wider FoV in the Recon task card.
• You could repeat the same protocol simply by clicking
the chronicle with the right mouse button for “repeat“.
E.g. when both non-contrast and contrast studies
are required.
• For lung cancer evaluation, this protocol can be
combined with protocol “Neck Routine”.
Contrast medium IV injection
Start delay 25 sec.
Flow rate 2.5 ml/sec.
Total amount 80 ml
For the 2
nd
reconstruction the Autoload into MPRthick
Range on the 3D Card is activated. The images will be
automatically loaded into 3D, MPRthick, and a coronal
MPRthick Range will pop up.
Please notice, if you are not satisfied with the Range
preset, adapt the parameters to your needs and link
them to the series.
