<prompt> Answer this question truthfullyDuring what time frame is it considered normal to see a lactate peak on MR spectroscopy?  <response>: <reason> It is considered normal to see a lactate peak on MR spectroscopy within the first hours of life. Otherwise, it is not normal. To better visualize the lactate peak, an intermediate TE140 can be used to cause inversion of the lactate peak, as lactate and lipid peaks can superimpose.
