What You Need To Know About Preclinical Imaging
Molecular medicine as an independent academic subject has gained interdisciplinary recognition.It has attracted professionals from areas as widely and distinctive as cardiology, oncology,immunology, neurology, biology,chemistry, genetics, genomics,nuclear medicine, radiology and pharmacology.
Molecular imaging is used to identify the source of disease carriers through the combined use of molecular biomarks and probes, using a variety of preclinical imaging techniques.
The non invasive visualization of molecules or molecular events using highly specific targeted probes is molecular imaging.It provides measurement and characterization of biological processes in living animals and humans.
Molecular imaging is non invasive, and it provides images of both physical and functional aspects of the living body.It tests and develops new techniques to image specific molecular pathways in vivo, especially those that are key targets in disease processes.
As opposed to other imaging techniques, this imaging technique produces images of tissues within a living organism.Other imaging techniques such as CT, X rays, and ultra sound capture the phenotypic changes at the gross anatomic level that result from molecular processes, while molecular images provides information about the biological processes.
Molecular imaging is performed by attaching a fluorescent tag with high specificity to the molecule of interest, which will be detected by the emission of fluorescent light when exited optically.
The key elements that are necessary for molecular imaging are:The important elements necessary for molecular imaging are as follows:The following are the key elements for molecular imaging:The image probes are highly specific and highly harmonious for their targets and acceptable biological delivery, Identification of the specific needed targets, the right amplification strategies, and sensitive fast imaging systems that have a high resolution.
Compared to other imaging techniques the Molecular resolution imaging has the following advantages.Molecular imaging has a wider spatial resolution that is; it is in micrometers instead of being several millimeters, it also extracts physiologic and anatomic information simultaneously.
The molecular imaging is several magnitudes less sensitive; thus, reliable signal amplification strategies must be developed.
As we have seen molecular imaging can look through the tissues of a living being and provide imaging in a non invasive way, that is the reason why it has been used in the identification of cancer cells. In this segment, we shall look at other ways to ensure that one is at a better advantage when it comes to cancer.
The earlier cancer is found, the easier it can be treated.Doctors can use technologies such as preclinical molecular imaging to detect the signs of cancer, however, you too can check your body for signs.
It is good to note that not all body changes mean that you have cancer.There are, however, a few checks you are recommended to do often, just stay in touch with what is normal for you.
Skin cancer is one of the common types of cancer, and it often sows visible signs; thus a full body check in the bathroom with a pair of mirrors is worth your while.The Skin Cancer Foundation has a guide that you can use yourself to check, as it is both useful and reassuring.This can be done once a month just so you can keep track of any changes that might occur, needless to say, if you spot anything like a mole or patch of discolored skin make an appointment to see your doctor.
Most lumps are not cancerous and can go away on their own.It is more reassuring to take any lump you find to a doctor.Doctors agree that is better to check and find nothing than wait until it is more difficult to treat.
