Magnetic resonance – indications, preparations and process
Over the past few decades, there has been a rapid development in medical imaging research. Diagnostic imaging in a non-invasive way to obtain images of the interior of the object under study. Among the leading techniques in diagnostic imaging is certainly Magnetic Resonance (MRI), which uses a high-intensity magnetic field produced by a superconducting magnet. RM imaging does not use potentially harmful X-rays. It is a modern, highly accurate method that shows cross-sectional images of organs in different planes.
The first center using magnetic resonance (MR) was launched by American pathologist Robert Kagan in a building purchased from the McDonald’s chain’s. NMR Scan Center began operations on April 1, 1984. Squareowka received by the patientow from 7 am to 11 pm seven days a week. In the same year the first scanners were approved. From the first day of RM use, the odniosł spectacular scientific and commercial success.
What are the indications of RM
RM examination gives very good images of the muscular and skeletal system a particularlyoln the spine. It is great for diagnosing canceroin and conditionoin inflammatory. It is indispensable in the study of the cardiovascular system. Allows detection of the elementoin invisible on X-ray examinations such as bone marrow diagnostics. Doctors order MRI in diseases of the central nervous system (multiple sclerosis, Alzheimer’s disease, cancer, tumors mozg and spinal cord etc.), in soft tissue diseases (inflammations, tumors, joint injuriesow, ligaments and muscles), with diseases in the chest and pelvis (heart and lung tumors, organ tumorsoin the genitals or prostate, large vessel disease).
Absolute contraindication of RM is any presence of elementoin metal within the potential patient’s body (e.g. pacemaker, prosthesis, implants, etc.).
Preparation for RM
The patient for RM examination should be properly prepared. Take solid medications and fast for 3 hours before the test. Clothing should be warmer (in the RM room temp. is 15 – 20 st. C.) and devoid of elementaloin metallic. The general rule is not to bring any objects into the RM roomoin teeth containing metal elements (e.g. watches, credit cards, dentures, electronics, etc.). The patient should be prepared to assume a stationary position during the examination tj. 20-60 minutes. If contrast administration is needed, up-to-date testing of creatinine levels is necessary. For examinations, you must arrive 15 minutes early to fill out medical questionnaires.
