Technical Principles and Protocols of PET/MR Imaging

摘要: PET and MRI are two well-established medical imaging modalities that used frequently as diagnostic tools in a wide range of clinical indications providing complementary information. can provide anatomical information with very high spatial resolution, functional measurements at organ tissue level sensitivity. On the other hand, images processes cellular sub-cellular specificity tracer detection sensitivity (10−11–10−12 mol/l) but an inferior to resolution. This matching capabilities renders both PET(/CT) necessary several disease pathways, particularly oncology neurology. A significant workflow limitation, when needed, is physical organisational separation systems. Patients needing MR referred independently often imaged after amount time. fusion from examinations difficult or even impossible due status changes technical factors. It is, therefore, expected where preferred modality versus CT, PET-MR should be more clinically useful than PET-CT combined single examination could benefits patient hospital.
