Thanks for this unique information. I am looking forward the new version of PI-QUAL system, because it is really help me to say urologist about their patient's mri quality. I am agree with your idea about US certification and accreditation, it is really help everybody to improve the quality of mri and reports. It is sound sad, but i can trust only a few center of MRi in Russia, who make high quality multiparametric MRI. And another hospitals can do what they can (pi-qual 2-3) and use PI-RADS2.1 for their reports. It is the main idea why i can not work with different hospital in my country. But you should know that we follow your advices, thanks again.
