To learn general principle of CT perfusion imaging and common acquisition protocols To understand how to interpret perfusion parameters To review post processing techniques used in current practice and learn common artifacts to avoid misinterpretation  

Scanner requirements: volume scanner, dual source (Helical Shuttle), dual energy Influencing parameters : spatial resolution, noise, temporal resolution, pitch, slice thickness Data acquisition protocols: scan duration, frequency of sampling, reconstruction interval, anatomic coverage Contrast related issues: dose, iodine concentration, injection rates , dual phase Arterial input and venous output functions Mathematical modeling techniques: Compartmetal model, deconvolution analysis Perfusion parameters: volume, flow, mean transit time, pemeability Anatomical differences: single versus dual supply tissue perfusion Clinical applications: stroke, myocardial ischemia, body (lung, liver, kidney) imaging, oncological application, Radiation dose issues Artifacts; patient related, beam hardening, cone-beam, misregistration, post processing
