Molecular medicine – as a developing independent Subject – has come to be positively attracting professionals from places widely distinctive as cardiology, oncology, immunology, neurology, biology, chemistry, genetics, genomics, nuclear radiology medicine and pharmacology.
By attaching a tag, Imaging is performed Or tag to the molecule of interest, which is detected by the emission of light when excited with specificity. Molecular imaging intends to show the source of disease carriers through the combined use of molecular bio-markers and probes, employing a huge variety of preclinical imaging methods. Preclinical molecular imaging is the visualization of Molecules or molecular events using highly targeted probes. It is used to provide characterization and measurement of biological processes in living animals and humans (in vivo).
Molecular imaging is a research discipline of Non-invasive imaging technologies which may create images of functional and bodily facets of the body. MI is directed at testing and developing novel techniques specific molecular pathways in vivo, especially the ones that are targets in disease processes. Rather than other conventional imaging techniques (like Microscopy), this imaging technique creates images on tissues within a living organism. Preclinical imaging primarily provides info about biological procedures (function) while additional imaging techniques like CT, X-rays, MRI and ultrasound, capture the phenotypic changes in the gross anatomic degree that result from molecular procedures.
During the past few decades Magnetic Resonance Imaging (MRI) – especially, preclinical MRI – and Magnetic Resonance Spectroscopy (MRS), have proven themselves to be extremely helpful for research applications from the various Life Sciences. Neuroscience research is heavily reliant on animal MRI that Has, in many instances, become recognized as the benchmark for this area. Some of the programs of clinical and preclinical MRI include research regarding arthritis, oncology and metabolic disorders; as well as respiratory, gastro-intestinal and cardiovascular studies. Recent developments in molecular biology and genome research have resulted in increased use of MRI applications in animals. Rapid phenotyping of transgenic animals and imaging are but two applications which have extended preclinical MRI’s role.

The assortment of MRI applications includes brain and Organ imaging, tumor assessment, disease imaging. Other research applications include investigation of new contrast mechanisms and agents, monitoring gene expression, analysis of protein interactions, and determination of pharmacokinetics.
Although small animal scanners are superior to clinical Scanners concerning providing a far better signal-to-noise ratio, the available pulse sequences are not the same as those in clinical scanners, and the magnetic field strength is higher. Molecular imaging aims to reveal the source of disease Carriers through the combined use of probes and bio-markers, using a variety of preclinical imaging techniques. MR imaging has two advantages over other imaging techniques: higher spatial resolution (micrometer rather than several millimeters) and the fact that physiologic and anatomic information can be extracted simultaneously.
