PET/MRI could be alternative to PET/CT for liver lesions

October 28, 2013

PET/MRI is more than adequate in characterizing liver lesions and provides greater lesion conspicuity than PET/CT, offering clinicians a powerful alternative for oncology imaging, according to a German study published in the November issue of the European Journal of Radiology.

PET/MRI provided better diagnostic confidence due to soft-tissue contrast and complementary information from different MRI sequences, according to lead author Dr. Karsten Beiderwellen and colleagues from University Hospital Essen, University of Duisburg-Essen, and University of Dusseldorf (EJR, Vol. 82:11, pp. e669-e675).

"The inherent soft-tissue contrast coupled with the higher spatial resolution of MRI is the main advantage over PET/CT, providing the overall higher conspicuity of liver lesions," Beiderwellen wrote in an email to "Plus, diffusion-weighted [MRI] helps in delineating even small lesions and offers complementary information to PET."
