Chest and abdomen MR angiogram (aortic dissection MRI protocol)

-->

 

Indications: assess extent of aortic dissection 

Sequences:

·        Axial tru-FISP: common carotids through diaphragm

·        Coronal tru-FISP: aortic arch through iliac bifurcation

·        Coronal 2-D FLASH: aortic arch through iliac bifurcation

·        Oblique coronal (candy-cane) MRA (pre-, post-Gd)

·        Rotating 3-D maximum-intensity-projection reformats

·        Post-Gd axial 2-D FLASH with fat saturation: 10mm thickness, great vessels to iliac bifurcation

Comments:

·        Coronal 2-D FLASH for T1 characterization of hematomas.

Dictation template:

Pre-contrast axial and coronal tru-FISP, coronal 2-D FLASH acquired of the thorax and abdomen.  Dynamic oblique coronal MRA using Care Bolus timing of the thorax during the administration of 0.1-0.4 mmol/kg of intravenous Gadolinium contrast (up to 20 mL), with 3-dimensional maximum intensity projection (MIP) reformats performed.  Post-contrast thick-slice axial 2-D FLASH with fat saturation of the thorax and abdomen.
