چکیده

Flow dynamics in intracranial aneurysms and their adjacent parent vessels play important roles in the development and rupture of intracranial aneurysms. Combined with tagged MR imaging and the use of particle image velocimetry software, tagged MR image velocimetry reveals flow vectors, vorticity, and shear strains at each location in the aneurysm replica every 9 milliseconds. This technique is a promising and noninvasive technique for assessing hemodynamics in intracranial aneurysms.

Tagged MR imaging of intracranial aneurysm models.

We used tagged MR imaging to investigate the flow in two lateral and two terminal saccular intracranial aneurysm models of different neck sizes. Imaging was performed with a 1.5-T superconducting MR system using 2D fast spatial modulation of magnetization (SPAMM) sequences with an intersegmental delay of 25 milliseconds. The flow in the saccular aneurysm models varied with the shape and size of...

A CASE OF GIANT INTRACRANIAL ANEURYSM AND SYST EMIC LUPUS ERYTHEMATOSUS: AN INCIDENTAL OR AN ACCIDENTAL FINDING?

A twelve year old girl, an established case of systemic lupus erythematosus, was referred to us suffering from diplopia and nasal speech for a period of 3 months. Neurological examination was conducted which revealed a right-sided sixth nerve palsy and a pulsatile nasopharyngeal mass. Neurodiagnostic imaging studies confirmed a giant intracavernous internal carotid aneurysm. The malady of t...
