DCE-MRI for Pulmonary pharechyma

The chemotherapy is most common therapy method for lung cancer, whatever in prior or posterior, surgery or radiotherapy, there always combines chemotherapy. So trail the therapy of lung cancer become more important, PET/CT is the standard method which use radioactive isotopes Tc99 labeled macro-aggregated albumin, but ionization exposure and low spatial resolution are the disadvantage. Although magnetic resonance imaging of pulmonary parenchyma has been blocked by several factor, but as improvement in MRI techniques, there are wide investigation of pulmonary parenchyma, such as ventilation imaging and perfusion imaging. Dynamic contrast enhancement magnetic resonance (DCE-MRI) offers assessment pulmonary perfusion. There are advantages of non-invasive and high spatial contrast of parenchyma compare with CT and PET/CT. Some preliminary studies have been done in quantitative of DCE-MRI.
