Importance of neuropsychological evaluation after surgery in patients with unruptured cerebral aneurysms.

Background: We evaluated neuropsychological function before and after surgery in patients with unruptured cerebral aneurysms.

Methods: Neuropsychological functions in 43 patients with unruptured cerebral aneurysms were evaluated before and 1 month after surgery. The neuropsychological examination included the Mini-Mental State examination, "Kana-hiroi" test, Kohs Block Design test, and Miyake's Memory test.

[Assessment of hemodynamics of meningioma with dynamic MR imaging].

Dynamic MR imaging provides hemodynamic information about normal and pathologic tissue of the brain. The purpose of our study was to evaluate the usefulness of dynamic MR imaging in the assessment of tumor vascularity and the tumor tissue blood flow of meningiomas. We studied 13 patients with meningiomas using dynamic spin-echo MR imaging.
