Molecular Diseases 4 : Chemistry

In medical diagnosis it is adopted mainly on the knowledge of diagnostic imaging technology spectrum, including the use of X-rays and gamma rays from, which is characterized by being electromagnetic radiation ionizing radiation, then began to think about using the term of this non- ionizing radiation infrared or microwave radiation and technical NMR magnet. The examples of spectral techniques used in diagnostic imaging:* X- rays* Gamma- ray* Ultrasound* Infrared* Anti electric tissue* Visual mechanismsX-rayThe oldest techniques that is used in diagnosis and therefore will not focus on the importance of being where they were getting on the first pictorial representation of various tissues obtain after the development that is built on a limited computer assistance.Gamma raysThe purpose of gamma-ray is the imaging profile then it was developed as computer- assisted also in the eighties which was called "ECT" and was then developed using imaging "Postiron emission tomography (PET)" where the radiation of tissue is carried out by position (positively charged) and thus can get a picture to clarify the life processes of the tissues that carry electrons and draw.UltrasonographyThe speed of these waves are characterized by being less of electromagnetic waves, which provides an opportunity to measure the fetus as well as during the stages of development in the womb, added to that the fact that this technique is based on the fact that the X-ray is not ionized therefore it is not a preferred use in diagnostic imaging Nuclear magnetic resonance imagingDespite this technology it is old, but it was then developed for the purpose of medical diagnostic imaging has gone from the seventies, where the nuclei of atoms is measured by the disposal of certain substances found in different body tissues. The criterion for the disposal of these seizures depends on the radio pulses that are similar to the frequency in the field of outer-core magnet and thus to obtain a diagnostic can be used.In the medical applications for the purification of nuclear magnetic resonance imaging to obtain imagery of infarction that occurs in some parts of the brain and important developments in this area the integration of multiple techniques and access to advanced apparatus for nuclear resonance imaging, including the "TMR" and "MRI". It is important experiments that experiments are used the magnet resonance imaging of kidney transplantation, which was filmed nearby parts of the kidney and then infected the interactions that take place within the body after transplantation and efficiency of the cultivated parts. As well as imaging of tumors within the liver and liver imaging at the time of myocardial fibrosis or within, as possible, filming parts of the stomach and colon and to identify tumors. It was also to obtain information about stroke and is believed to imagery obtained of cancerous tumors of the brain were more pronounced than the use of X- ray.It can be measured by any inflation occurs as a result of heart disease, and can also study the problems of the heart due to the presence of any obstruction or infarction in one of the blood vessels and could also portray the evolution of stroke, heart attack and its impact on the heart.
