Opis

Molecular imaging is an emerging technology that provides images to visualize specific molecular changes in various diseases in living species. The main tools for scintigraphy are positron emission tomography (PET), single photon emission computed tomography (SPECT) and magnetic resonance imaging (MRI). SPECT require a radio-labeled pharmaceutical (radiopharmaceutical) in the diagnosis of many common diseases associated with the malfunctioning of organs as well as in the detection of certain type of cancers. SPECT is a nuclear imaging technique that provides a 3D spatial distribution of single-photon emitting radio nuclides within the body. MRI makes use of the property of nuclear magnetic resonance (NMR) to image nuclei of atoms inside the body. The body is largely composed of water molecules. Each water molecule has two protons. When a person is inside the powerful magnetic field of the scanner, the average magnetic moment of many protons becomes aligned with the direction of the field. The strong expansion of medical MRI has prompted the development of a new class of pharmacological products, called contrast agents.

O autorze

Dr. Nisha Saini is an assistant Professor at Gargi College University of Delhi New DELHI INDIA. I defended my Ph.D in INMAS, DRDO, Ministry of Defence, INDIA. The topic of my research is the synthesis and biological evaluation of SPECT and MR contrast agents. I published so far three papers in this field and few are in progress.
