[Abstract] Objective: To investigate the application value of magnetic resonance spectroscopy (MRS) in the treatment of hyperacute cerebral infarction by using stimulated echo acquisition mode and short echo time scan.Materials and Methods: The patients of hyperacute infarction treated with thrombolytic therapy or non-thrombolytic therapy underwent regular magnetic resonance and MR spectrum scan after 1 week of hospitalization. Then we respectively analyzed the ratios of NAA/Cr, Cho/Cr and NAA/Cho in the infraction center, the border region, the normal region around the lesion and the contralateral area.Results: (1) In the non-thrombolysis group, in the infraction center,the ratios of NAA/Cr, NAA/Cho decreased significantly, the ratios of Cho/Cr and mI/Cr were higher than in the border region, the ratio of Glx/Cr was higher than that in the contralateral area (P<0.05). In the border region, the ratio of AA/Cr was lower than in the normal region around the lesion, and the ratio of NAA/Cho was lower than in the contralateral area (P<0.05). The ratios of NAA/Cho, Cho/Cr and Glx/Cr in the infraction center and Lac/Cr in the border region were significantly correlated with the clinical NIHSS score (r=-0.626, 0.629, -0.689, 0.812, P<0.05). (2)In the thrombolysis group, in the infraction center, the ratio of Cho/Cr was higher than in the border region. In the border region, the ratios of NAA/Cr, mI/Cr were lower than in the contralateral area, and the ratio of NAA/Cho was lower than in the normal region around the lesion. The ratios of NAA/Cho, Cho/Cr, mI/Cr and Glx/Cr in the infraction center and Lac/Cr in the border region were significantly correlated with the clinical NIHSS score (r=-0.686, 0.791, -0.757, -0.791, 0.735, P<0.05). (3) In the thrombolysis group, the ratios of NAA/Cr, NAA/Cho and mI/Cr in the infraction center, the border region was significantly higher than in non-thrombolysis group, the ratio of Lac/Cr in the infraction center, the border region and the normal region around the lesion was lower than that in non-thrombolysis group, the ratio of Glx/Cr in the infraction center was significantly higher than in non-thrombolysis group.Conclusions: 1H-MRS can detect more metabolite changes by using short echo time scanning and more comprehensively detect the recovery of damaged brain tissue after the clinical treatment. It can objectively evaluate the effect of clinical treatment and prognosis of cerebral infarction, providing objective imaging evidence for clinical application. |
