SPECT-computed tomography in rats with TNBS-induced colitis: A first step toward functional imaging

Figure 4 Association between SPECT-computed tomography parameters with inflammatory markers in rats with 2,4,6-trinitrobenzene sulfonic acid-induced colitis. Colitis was induced in rats by intrarectal injection of TNBS at day 0. SPECT- computed tomography was performed at day 2. A: Simple linear regression between maximal thickness and colon cycloxygenase-2 expression; B: Simple linear regression between pixel max and colon weight:length ratio; C: Simple linear regression between colon diameter and colon cycloxygenase-2 expression; D: Maximal thickness according to histological inflammation score.
