PET/MRI accurate in detecting liver metastases

September 11, 2015

Researchers found that the use of positron emission tomography with [18F]FDG in combination with magnetic resonance imaging was more accurate in detecting liver metastases compared with positron emission tomography with computed tomography, according to published findings.

“While [CT] represents the clinical standard in abdominal tumor staging, [MRI] of the liver, with its excellent soft tissue contrast, offers a higher sensitivity especially in liver lesions sized [less than] 10 mm,” the researchers wrote. “Positron emission tomography … with [18F]FDG, usually in combination with CT, enables a further characterization of liver lesions based on their glucose metabolism. … MRI, however, is known to show a higher sensitivity and accuracy in the detection of small liver lesions compared with CT, as well as with PET/CT, making it is a promising alternative to CT in hybrid imaging.”
