A total of 35 patients with
aphasia after
cerebral infarct were included. Among them, 15 conjunctures were sensory (Wernicke's)
aphasia and 20 cases were motor (
Broca) aphasia. Perfusion Weighted Imaging (PWI) and Magnetic Resonance Spectroscopy (MRS) were performed on the attached hard area to measure the local cerebral blood flow (rCBF) and sectional cerebral blood compass (rCBV), mean conveyance tense (MTT), point delay (
TTP), and
N-acetylaspartate (NAA),
choline (Cho),
creatine (Cr)), and lactic acidic (
lactate, Lac) and generally a relative analysis. Results. Among the patients with contaminative
aphasia, rCBF was way diminished in the contralateral mirror extent. MTT and
TTP were significantly longer than the contralateral mirror range, NAA and Cho were sullenness than the contralateral side, and the Lac peak appeared. The distinction was statistically taken (P < 0.05). Compared with the contralateral mirror circumference,
motor aphasia was significantly reduced in rCBF and rCBV, and MTT and
TTP were way prolonged. NAA and Cho were reduced compared with the contralateral side, and the Lac peak appeared. The dispute was statistically momentous (P < 0.05). Conclusion. After
cerebral infarction, the language cosine extent of patients with
aphasia bestows a rank of hypoperfusion and light metabolism, suggesting that it may be the pathogeny of
aphasia.
