Contrast Agents for Computed Tomographic Imaging

Medical imaging infers detailed pictures of processes inside the subject’s body without an invasive approach. In a nearly decade-old development, molecular imaging has gained attention as a noninvasive approach to cellular and subcellular imaging explaining chemical and biological processes. Chemistry, biology, and engineering and their triad combinations have led from clinical imaging to biochemically based assessments surging from a mere anatomical static picture of the situation. Such developments would provide information that is unattainable with other imaging technologies as it identies disease or a functional or building block abnormality in its earliest stages and determines its exact location-often before symptoms occur or abnormalities can be detected with other diagnostic tests [1-4].
