Excerpt
Quantitative analysis of myocardial perfusion SPECT (MPS) studies has become a mainstay in nuclear cardiology practice. Software tools developed by several groups are now commercially available and are routinely used. These programs can automatically compute several important clinical parameters, such as amount of hypoperfusion at stress and rest. What is the value of these tools to a nuclear cardiology practitioner or a clinical researcher? How do they compare to visual analysis? What are their limitations? In this review, we look at the standard features of such quantitative tools, compare it with the visual scoring technique, and discuss particular strengths of the quantitative approach. We also highlight several possible challenges in applying quantitative analysis and discuss some recent software developments, which can mitigate these difficulties. …
