MRI and PET/CT Comparable in Detecting Cancer Metastases

October 9, 2012

Whole-body (WB) scans using either magnetic resonance imaging (MRI) or positron-emission tomography (PET) with CT are highly sensitive and specific for distant malignancies in patients with cancer, a meta-analysis by a team from Nanning, China has shown.

Furthermore, the researchers report, "The combined use may provide more added value than WB-PET/CT and WB-MRI alone."

In a paper online September 12 in Annals of Oncology, Dr. C.Y. Li at The First Affiliated Hospital of Guangxi Medical University, and colleagues explain that several studies have compared whole-body PET/CT with MRI for detecting distant malignancies - whether metastases or second primary tumors -- in cancer patients. However, the results have been controversial.
