Postoperative CBF increased areas displayed in transverse sections.

Increased ratio (%) at the area of significantly increased CBF on postoperative SPECT compared with preoperative SPECT is shown by using SPM8 with DARTEL (a) and SPM8 without DARTEL (a conventional method) (b). Images were reconstructed shown in 6mm thickness and the increased ratio was less than 15% in both methods. SPM8 with DARTEL revealed larger CBF increased areas (a), on the contrary, the conventional method showed relatively smaller CBF increased areas which were located in more medial regions compared with those with DARTEL.
