Acquisition
- Use gammacamera with paralell high resolution collimator for imaging. Ideally, a fan beam collimator is preferred.
- At 45min after injection, obtain 360° Spect, 128 views, 20 sec, step and shoot, circular orbit with 128 x 128 matrix.
- In cases of acetazolamide and Wisconsin test, perform a baseline and post-stimulation study.
