Magnetic Resonance Spectroscopy

Nuclear magnetic resonance spectroscopy is a new type of high-tech imaging examination method in recent years. It is a new medical imaging diagnostic technology that was applied to the clinic in the early 1980s. It has no ionizing radiation (radiation) damage; no bone artifacts; multi-directional (transverse, coronal, sagittal section, etc.) and multi-parameter imaging; high soft tissue resolution; vascular structure can be displayed without the use of contrast agents And so on. Basic Information Specialist classification: Oncology examination classification: Nuclear magnetic resonance Applicable gender: whether men and women apply fasting: fasting Tips: Pay attention to rest before the examination, reasonable diet, follow the doctor's advice, and prevent fatigue. Normal value The inspection result is normal and there is no abnormal area. Clinical significance Abnormal result Indications: Neurological diseases including tumors, infarction, hemorrhage, degeneration, congenital malformations, infections, etc. are almost a means of diagnosis. In particular, lesions of the spinal cord, such as tumors of the spine, atrophy, degeneration, and traumatic disc disease, have become the preferred method of examination. Lesions of the great vessels of the heart; lesions of the mediastinum in the lungs. Abdominal pelvic organs examination; biliary system, urinary system, etc. are significantly better than CT. For soft tissue lesions of the joint; it is very sensitive to aseptic necrosis of bone marrow and bone, and the lesion is found earlier than X-ray and CT. People who need to be examined: cancer patients. Precautions Taboo before inspection: no special contraindications. Requirements for inspection: Check your relaxation and follow the doctor's instructions. Inspection process The content of some compounds and metabolites in the tissue and their concentrations. Since the atomic protons in each tissue are in the form of certain compounds, these compounds or metabolites have a certain chemical shift in a certain chemical environment, and There are small changes in the peaks in the magnetic resonance spectrum, and their small changes in peak and chemical concentrations are acquired by a magnetic resonance scanner, which is converted into a numerical spectrum. These chemical information represent the concentration of the corresponding metabolite in the tissue or body fluid, reflecting the metabolic state of the tissue cells. That is, magnetic resonance spectroscopy expresses its pathological changes in terms of tissue cell metabolism. Not suitable for the crowd Inappropriate crowd: 1. Those who install artificial heart pacemakers and nerve stimulators are forbidden to check. 2. It is forbidden to check if there is a silver clip in the skull and a metal foreign object in the eyeball. 3. The ECG monitor cannot enter the MRI examination room. Those who have undergone arterial surgery, have had heart surgery and have an artificial heart valve are forbidden to check. 4, a variety of critically ill patients: such as coma after trauma or accident, irritability, arrhythmia, respiratory insufficiency, constant blood loss and incontinence and so on. 5. Metal objects (such as internal fixed steel nails) cannot be inspected at the inspection site. 6. Pregnant women should be examined carefully. If they are pregnant, please inform the doctor. Adverse reactions and risks Nothing.
