[Abstract] Objective: To investigate the application value of high-resolution magnetic resonance imaging(HR-MRI) in measuring intracranial aneurysm by a comparative analysis with three-dimensional digital subtraction angiography (3D-DSA), three-dimensional time of flight magnetic resonance angiography (3D-TOF MRA).Materials and Methods: A total of 25 patients diagnosed of intracranial aneurysm were enrolled in department of neurosurgery of our hospital from October 2013 to March 2015. Among them, 15 cases were male and 10 female, age 5-60 years old, median age 50.5 years. Firstly all of them underwent conventional MRI sequence to verify the location of intracranial aneurysm, then 3D-TOF MRA sequence was performed, thirdly we performed HR-MRI sequence according to 3D-TOF MRA images (one patient was excluded for poor image quality). And they underwent DSA examination in a week. We measured the maximum width of intracranial aneurysm on the images of 3D-TOF MRA, HR-MRI and 3D-DSA. Statistical analysis was performed using a paired sample Student’s t-test for the pairwise comparisons of the differences among HR-MRI, 3D-DSA and 3D-TOF MRA in measuring the maximum width of intracranial aneurysm. We assume the difference is significant statistically when P<0.05.Results: In the aspect of measuring the maximum width of intracranial aneurysm, the differences between HR-MRI and 3D-DSA (the mean difference was 3.16±2.66 mm), HR-MRI and 3D-TOF MRA (the mean difference was 5.15±4.89 mm) were significant statistically (P1<0.05, P2<0.05), respectively, and there was no statistical significance between 3D-DSA and 3D-TOF MRA (the mean difference was 2.53±5.18 mm, P3>0.05).Conclusion: There were differences between HR-MRI and 3D-DSA, HR-MRI and 3D-TOF MRA in measuring the maximum width of intracranial aneurysm, HR-MRI may have higher clinical application value in measuring the actual size of intracranial aneurysm accurately.
