  1. The scans and corresponding reports of 103 CJD patients were reviewed. The population comprised 91 sCJD, 7 vCJD, 2 iCJD and 3 IPD patients. The number of scans with DWI is shown as is the incidence of CJD-associated changes as noted by NPC and referring centre.
  2. *= 2 of the 7 patients had MRI changes normally associated with sCJD.
  3. **= p<0.0001 compared with NPC opinion of CJD-associated changes using Chi2 with 1df and Yates’ correction.
