German researchers conducted a study in an effort to investigate the difference between combining Positron Emission Tomography (PET) with (MRI) Magnetic Resonance Imaging compared to PET with Computed Tomography (CT).

The scientists published their findings in the Journal of Nuclear Medicine, where they concluded that pairing (PET) with (MRI) is more effective at detecting lesions. This discovery yields a quicker, more effective use of centralized and whole-body staging in a single step. Moreover, it reduces the level of radiation exposure, making them ideal for younger patients.

PET/CT is typically the customary route in oncology imaging and staging due to its high sensitivity and resolution. However, PET/MRI offers higher soft-tissue distinction with lower radiation exposure. This combination has been prevalently dampened because there have not been enough significantly conclusive studies to exhibit both functionality and advantages.

The analysis was conducted by board-certified nuclear medicine physicians and radiologists who determined that PET/MRI made the process of discovering lesions and classifying them easier. Researchers noted that reduction in radiation exposure was perhaps the most significant advantage of PET/MRI over PT/CT.

Further studies are needed to improve the detection of nodules with PET/MRI; however, the scientists’ conclusions highlight the increasing potential of hybrid imaging with oncology diagnostics.
