"Volume rendering provides useful 3-D images of the aorta and its great vessels allowing vascular surgeons an unsurpassed view of complex vascular anatomy important for planning the surgical approach."
Clinical Case Overview:
78 year old male with decreased blood pressure in the left arm.
Case Study:
| Image 1 is a volume rendered reconstruction of a breath hold 3D T1 weighted gradient echo MR angiogram of the aortic arch performed in 20 seconds. There is a right-sided aortic arch and an aberrant origin of the left subclavian artery. |
 |
| Image 2 is a volume rendered image showing a markedly atretic left subclavian artery. Reconstitution of the left subclavian and left vertebral artery occurs from large collaterals arising from a thyro-cervical branch off the descending thoracic aorta. |
