Assessment of PET and SPECT Scanning Systems Introduction The study of positron emission tomography (PET) and single photon emission computed tomography (SPECT) scanning effectiveness in supporting better public health outcomes has been proven with the accuracy these devices provide in diagnosing illnesses and potentially sever medial conditions. The costs of a PET scanning system can easily surpass $1M in system costs alone however (Wagner, 1988). SPECT systems are equally expensive which make both of these systems' availability limited to only the most prosperous and wealthy areas of the world (Lejeune, Zahouri, Woronoff-lemsi,, et.al., 2005). One study indicated that over 95% of scans from these systems are entirely paid for by insurance programs that have specific preconditions defined for patients as the average cost can easily exceed $20,000 per full scan (Lejeune, Zahouri, Woronoff-lemsi,, et.al., 2005). The intent of this analysis is to evaluate the effectiveness of PET and SPECT scans in supporting better health outcomes, in addition to analyzing the benefits of these technologies to who has access to their tests. There is also an analysis of the diseases these technologies are most adept at diagnosing. Analysis of the Effectiveness of PET and SPECT Scanning Systems The PET scan technology is most effective for completing advanced analysis of Alzheimer's disease by measuring the chemical concentrations of sugar in the bran, and through a comparable
