Vessel size imaging (VSI) quantifies cerebral blood vessel size in brain tumor patients, revealing tumor-type-specific differences. Quantitative accuracy is improved with higher contrast agent susceptibility and additional physiological measurements.

Area of Science:

  • Radiology
  • Neuroimaging
  • Medical Physics

Background:

  • Contrast-enhanced transverse relaxation rates (R2* and R2) enable in vivo mapping of cerebral vessel caliber.
  • This technique, known as vessel size imaging (VSI), offers insights into neurovascular morphology.

Purpose of the Study:

  • To quantitatively assess cerebral vessel caliber in brain tumor patients using VSI.
  • To investigate the relationship between vessel size and tumor type.
  • To analyze the theoretical underpinnings and limitations of VSI.

Main Methods:

  • Utilized the relationship between R2* and R2 relaxation rates for VSI.
  • Performed quantitative assessment of mean vessel size in brain tumor patients.
  • Conducted theoretical analysis of VSI's morphological information content and data processing.

Main Results:

  • Mean vessel size demonstrated sensitivity to different tumor types.
  • Theoretical analysis elucidated the morphological information content of VSI.
  • Identified systematic overestimation of vessel caliber due to simplified VSI theory.

Conclusions:

  • VSI is sensitive to tumor type, offering diagnostic potential.
  • Quantitative accuracy of VSI can be enhanced by increasing contrast agent magnetic susceptibility.
  • Accurate quantitative VSI requires incorporating regional diffusion coefficient and cerebral blood volume measurements.
