For Mesothelioma Staging PET/CT Tops PET/MRI

PET Scan

Standard PET/CT beats PET/MRI for diagnosing and staging pleural tumors such as mesothelioma. That is the conclusion reached by a team of radiology researchers in Zurich who evaluated  the two imaging modalities side-by-side for a variety of different cancers, including mesothelioma. Positron emission tomography is a nuclear imaging technique that produces 3D images of functional or metabolic processes in the body. Patients are given a radioactive tracer (usually FDG, a molecule similar to glucose) and the PET machine detects concentrations of the tracer in body tissues. Because FDG is an analog of glucose, it will concentrate where metabolic activity is highest, often in cancer cells. The combination of PET with computed tomography, an X-ray imaging study that produces tomographic images or … Continue reading For Mesothelioma Staging PET/CT Tops PET/MRI »
