Summary

Magnetic resonance imaging (MRI) data can be used for virtual intraarterial endoscopy (VIE) to visualize aortic pathologies. This technique successfully depicted various conditions like dissections and stenoses from an intraluminal perspective.

Area of Science:

  • Medical Imaging
  • Cardiovascular Radiology
  • Endovascular Techniques

Background:

  • Conventional angiography is the standard for evaluating aortic conditions.
  • Minimally invasive imaging techniques are crucial for detailed vascular assessment.

Purpose of the Study:

  • To assess the feasibility of virtual intraarterial endoscopy (VIE) using magnetic resonance (MR) imaging data.
  • To evaluate VIE's capability in visualizing intraluminal aortic pathologies.

Main Methods:

  • Three-dimensional gadolinium-enhanced spoiled gradient-echo MR imaging was performed on 21 patients.
  • Prototype software with ray casting algorithms was used for VIE postprocessing.
  • Conventional angiography served as the reference standard for comparison.

Main Results:

  • VIE successfully visualized the vessel wall from the inside in all cases.
  • Pathologic conditions clearly depicted include congenital double aortic arch, coarctations, Leriche syndrome, stenoses, occlusions, and aortic dissections.
  • The technique differentiated true and false lumina in dissections.

Conclusions:

  • Virtual intraarterial endoscopy (VIE) is a feasible technique for assessing aortic conditions using MR imaging.
  • Image quality, artifact thresholding, and inherent smoothing are current limitations.
  • VIE offers a novel intraluminal perspective for cardiovascular imaging.
