City Hospital has two MR scanners, one operating at 1.5T and one at 0.5T. After correctly following hospital policy for screening patients for an MR Scan, Mr. Black begins his exam on the 1.5 T scanner.

There are several factors the MR technologists need to consider when scanning on magnets operating at different field strengths The following TR values were to be used on the 1.5 T scanner (T1W-TR=700 msec; T2W-TR=2500 msec) for a T1W and T2W acquisition. What TR values should be used to achieve the same T1 and T2 tissue weighting on the 0.5 T scanner?
