This article by Hsu et al from the NIH shows
promising diagnostic accuracy for a new fully automatic, pixel-wise, quantitative stress perfusion by CMR: Diagnostic Performance of Fully Automated Pixel-Wise Quantitative Myocardial Perfusion Imaging by Cardiovascular Magnetic Resonance.
However, these approaches have not yet delivered all that they
promised, partly due to the inherent genetic variability between patient samples, but also because the
diagnostic / prognostic
accuracy of the cancer signatures identified tends to be linked to the patient cohorts from which those signatures were obtained.
