 Magnetic resonance imaging MRI is a diagnostic study that makes pictures of organs of the body using magnetic field and radio frequency pulses that can not be felt. Dynamic contrast enhanced-magnetic resonance imaging DCE-MRI uses faster imaging and contrast material a substance used to make specific organs, blood vessels, or tumors easier to see that is given by vein. Diffusion weighted magnetic resonance imaging DW-MRI allows to measure the motion of water around the cells in the tumor. Proton magnetic resonance spectroscopy MRS obtains chemical information from the tumor. During MRS, signals are detected from the chemicals spectroscopy naturally present in your tumor using radio waves. DCE-MRI, DW-MRI and MRS give extra information which is not available with the regular MRI. The regular MRI only shows pictures of the tumor while the DCE-MRI also gives information about the blood vessels of the tumor. DW-MRI provides information related to the state of the tumor tissue with regards to the quality or condition of cells present in it and MRS gives information about the chemical makeup of the tumor.
