PET/MR is having a hard time keeping up with PET/CT as a prime imaging tool in clinical practice, according to a review in the Journal of Nuclear Medicine. PET/CT's wider distribution and lower cost are just some of its advantages over PET/MR. The varied advantages and disadvantages for each individual PET/MR setup make it difficult for medical staff trained in using PET/CT to understand morphostructural or functional data gathered from PET/MR, which would be helpful in the treatment of inflammatory and chronic diseases. The authors laud PET/MR's ability to produce functional information and urge experts to educate themselves about its potential for clinical use.
