Multislice CT in the pre- and postinterventional evaluation of mesenteric perfusion

Area of Science:

• Radiology
• Vascular Imaging
• Medical Diagnostics

Background:

• Multislice computed tomography angiography (CTA) has advanced significantly with new technology.
• Previous limitations in speed and resolution have been overcome.

Purpose of the Study:

• To present a spectrum of visceral vascular diseases.
• To showcase interventional and surgical therapies.
• To highlight the role of postprocessing in CTA evaluations.

Main Methods:

• Utilizing multislice computed tomography angiography (CTA).
• Employing faster scanning speeds for improved volume coverage and contrast enhancement.
• Leveraging high spatial resolution for nearly isotropic voxels.
• Reconstructing high-resolution three-dimensional images using algorithms like volume rendering.

Main Results:

• CTA demonstrates feasibility for visceral vasculature evaluation.
• Faster scanning improves contrast medium exploitation and breath-hold capability.
• Higher resolution enables detailed 3D reconstructions and visualization from any viewpoint.
• CTA delineates vessels, adjacent structures, and organ perfusion, surpassing conventional angiography.

Conclusions:

• Multislice CTA is a valuable tool for assessing visceral vascular anatomy and diseases.
• It aids in pre- and postinterventional assessment.
• Postprocessing techniques are crucial for comprehensive evaluation.
