Overview
MRI may be helpful in stable patients with a severe dye allergy, as it does not require nephrotoxic contrast. However, it is less accurate than thin-slice CT, costly, not as readily available as contrast CT or ultrasonography, and less valuable in assessing suprarenal extension of an aneurysm.
MRI
Advantages
- MRI may be helpful in stable patients with a severe dye allergy, where CT scanning is contraindicated.
- MRI provides imaging of the aorta comparable to that with CT scanning and ultrasonogram without subjecting the patient to dye load or ionizing radiation.
- MRI also provides superior imaging of branch vessels compared with CT scan or ultrasonogram[1].
Limitations
- Lack of widespread availability
- Need for a stable patient
- Incompatible with monitoring equipment
- High cost
- Less valuable in assessing suprarenal extension of aneurysm
- Less accurate than thin-slice CT[1]
