To assess CT Perfusion (CTP) to monitor and assessment the basal ganglia metabolism status of acute hemilateral movement disorders patients.

12 patients with acute hemilateral limb movement disorder and were performed dynamic CT Perfusion examination with a 64-detector row CT scanner. The ratios of rCBF, rCBV and MTT in bilateral basal ganglia were measured and the ratios of left/right measurements were calculated in patients and the controls. One side basal ganglia ROI is handrawn along the grey matter margin of putamen, head of caudate nucleus and thalamus nucleus, the contralateral side basal ganglia ROIs were duplicated by the automated mirror ROI function of workstation. Statistical Analysis of the differences was conducted by mean of a two tailed t-test.

The difference between the bilateral side measured was analyzed, on a total of 12 patients, 4 (33%) no difference; 6 (50%) hypoperfusion on the symptom supposed side putamen; 2 (17%) presented hyperperfusion. 3 (33%) had no difference; 6 (50%) hypoperfusion; 3(17%) hyperperfusion on the symptom supposed side of caudate nucleus. 7 (33%) no difference; 4 (50%) hypoperfusion; 1 (17%) hyperperfusion on the symptom supposed side of thalamus.

CT Perfusion Weighted Imaging is an effective approach to access the alteration of rCBV in acute hemilateral movement disorder patients.

CT Perfusion Weighted Imaging can provide useful information of the functional status of the basal ganglia.
