[Use of long spin-echo sequences for imaging demyelinating diseases].
A multiple spin-echo-sequence has been evaluated in diagnosis of demyelinating diseases. TE in these MR-experiments was between 14 and 336 msec, TR between 860 and 1660 msec. Three groups of patients were examined, and it could be shown that the probability to detect MS-plaques grows with long TE's up to 300 msec. T2-relaxation-time-values range between 126 and 250 msec. Different MS-plaques in the same patient might show different T2-values.
