The Magnetic Resonance Imaging System Promises Many Clinical Treatments
Magnetic resonance imaging (MRI) is an advanced imaging system used for clinical purposes. It is a noninvasive technological modality that applies a combination of radiofrequency pulses, powerful magnetic field and a computer system to produce pictures of the body organs. The images taken by MRI technique are more clear and detailed than the images found by x-ray, ultrasound or CAT scan.
The clinical MRI images are used to detect tumor, blockages or enlargements existed in the blood vessels that can cause cancerous growth or abnormalities. As a discipline and in its widest sense, it is a part of biological imaging that incorporates nuclear medicine, endoscopy, investigative radiological science, thermography, microscopy and medical photography. Along with the developments in the health care sector, the magnetic resonance imaging technicians are needed in almost every hospitals and specialty diagnostic center.
There are mainly two forms of radiographic images used in the medical imaging – projection radiography and fluoroscopy. The two dimensional techniques are still in wide use despite the emergence of three dimensional tomography. The 2D images can be accessed at low cost, high resolution and lower radiation dosages. To extract good images under clinical magnetic resonance imaging system, the MRI technicians need special training and qualifications.
In MRI, any nucleus with a net nuclear spin can be used in the clinical setting. The nucleus, present in the water, allows the excellent soft-tissue contrast that can be achieved with magnetic resonance imaging techniques. During MRI procedure, technicians go through training program; they learn the basics of imaging equipment, conducting a MRI test and sophisticates computed software. One can also consult some editions of Clinical magnetic resonance imaging to find comprehensive examination of the newest technologies and clinical applications relevant to MRI of the brain, heart, spine, head and neck, and musculoskeletal system.
