A Study to Analyze Aneurysm Growth and Enhancement


About this study

The purpose of this research is to determine whether we can identify when changes in blood vessel shape over time are likely to occur, and to what extent those changes can be predicted by MRI studies. In order to determine that, we wish to investigate these methods in subjects who have aneurysmal disease.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. There is no guarantee that every individual who qualifies and wants to participate in a trial will be enrolled. Contact the study team to discuss study eligibility and potential participation.

Inclusion Criteria:

  • Patients will be recruited who are undergoing MR Imaging studies as part of their routine clinical care for untreated intracranial aneurysms where no interventional treatment is planned.
  • Consent to research.

Exclusion Criteria:

  • Unable to undergo MRI or have gadolinium (patients are already having these studies as part of routine clinical exam, so don’t foresee this being pertinent).
  • Atypical cause of aneurysm (e.g. infectious, related to atrial myxoma, dissecting, etc.).
  • Unable to remain still enough for diagnostic examinations.
