PPT-Contrast Media in M edical Imaging Techniques

What are contrast materials and how do they work Contrast materials also called contrast agents or contrast media are used to improve pictures of the inside of the body produced by xrays computed tomography CT magnetic resonance MR imaging and ultrasound Often contrast materials allow the radiologist to distinguish normal from abnormal conditions.
