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.
