FIG 2. Representative 1H MR spectra from infarcted and contralateral non-infarcted brain tissue using TEs of 136 ms and 272 ms (data from the same animal as that depicted in fig 1). The MR signals corresponding to H2O, TMA, creatine plus phosphocreatine, NAA, and related compounds, and lactate are identified. A five-times larger vertical scaling factor was used for the data collected using a TE of 272 ms, compared with the data collected using a TE of 136 ms.
A, 1H MR spectra of infarcted brain tissue (TE, 136).
B, 1H MR spectra of non-infarcted brain tissue (TE, 136).
C, 1H MR spectra of infarcted brain tissue (TE, 272).
D, 1H MR spectra of non-infarcted brain tissue (TE, 272).
