Imaging features of intracranial aneurysms on magnetic resonance 3 Tesla

Abstract

Objective: Describe the imaging characteristics of an intracranial aneurysm on 3 Tesla magnetic resonance at Bach Mai hospital Methods: A prospective study was performed on 29 patients with clinical manifestations of neuropathy who were diagnosed with 3 Tesla magnetic resonance brain aneurysms and then underwent digital subtraction angiography at the Radiology Center, Bach Mai Hospital, Hanoi, Vietnam from August 2021 to August 2022. Description of intracranial aneurysms in terms of number, location, shape, morphology and size measure. Results: Of the 29 patients, 37 aneurysms were detected on 3 tesla magnetic resonance and confirmed on digital subtraction angiography. The location of intracranial aneurysms is common in the anterior circulation (97.29%), and the posterior circulation (2.71%). Dimensions are mainly ≤ 10mm (97.3%). Usually saccular aneurysms (94.6%) and narrow neck (51.43%). Most aneurysms have irregular margins, knobs or two bases (72.97%). Conclusion: Magnetic resonance 3 Tesla can replace digital subtraction angiography erasing the background to characterize the image of intracranial aneurysms. This is a safe, non-invasive and highly valuable imaging method in the diagnosis of intracranial aneurysms, a very effective first choice for screening intracranial aneurysms and providing information for neurologists implement appropriate treatment strategies.
