ECT test

There are many ECT inspection projects, almost all organs and tissues of the human body. Suitable for early diagnosis and observation of curative effects. ECT is currently the most important nuclear medicine instrument. It combines gamma photography, mobile whole body imaging and tomography, and is mainly used for functional imaging diagnosis of various diseases. Unlike ultrasound, X-ray, CT, MRI and other "anatomical contrast" images, ECT uses the principle of a specific physiological or biochemical process in the body using a tracer. Basic Information Specialist classification: growth and development check classification: other inspection Applicable gender: whether men and women apply fasting: fasting Tips: Patients should fast for 6-12 hours before the examination and stop using atropine, Xintongding, Deshute, Dingsining, Cimetidine, Famotidine and gastric motility drugs according to doctor's advice. Normal value The various systems of the human body (cardiovascular, skeletal, endocrine, nervous, digestive, urinary, and respiratory) have their own examination programs and major indications. Clinical significance ECT is currently the most important nuclear medicine instrument. It combines gamma photography, mobile whole body imaging and tomography, and is mainly used for functional imaging diagnosis of various diseases. Unlike ultrasound, X-ray, CT, MRI and other "anatomical contrast" images, ECT uses the principle of a specific physiological or biochemical process in the body to display the spatial distribution of organ function information in an image manner. The computerized processing extracts quantitative analysis parameters for diagnostic analysis, the essence of which is "physiological contrast" image, because the functional changes of many diseases are earlier than the changes of anatomical structure, such as myocardial ischemia, transient cerebral ischemia, tumor bone metastasis, transplantation Renal rejection, ECT imaging sensitively reflects the changes in tissue function caused by these diseases, so it can achieve the purpose of early diagnosis, more abnormal than other imaging methods, high sensitivity; series observation of pre- and post-organic organs Changes in function can be used for therapeutic observation. Precautions 1, cerebral blood flow tomography: 1 and 2 days before the examination, the patient tried to stop the expansion of the cerebral vasculature to increase the sensitivity of the examination. 30-60 minutes before the injection of imaging agents, oral potassium perchlorate should be prescribed according to the doctor's advice to close the choroid plexus and thyroid to reduce interference. 5-10 minutes before and after the injection, the patient should try to rest, reduce the sound and light stimulation, stay in bed and keep calm and wear eye mask and earplugs until about 10 minutes after the injection of imaging agent. The head cannot be moved during the inspection to ensure the authenticity of the image. 2, myocardial perfusion imaging: the day before the examination should stop nitroglycerin, easy to pulse, Diao Xinxue Kang and other drugs. For example, it is best to stop the drugs such as propranolol, heart rhythm, betaloc, isobolidine, and methoxybenzamine in the first two days. Those who have undergone myocardial drug load testing should discontinue drugs such as dipyridamole, dobutamine, and aminophylline 24 hours before. Breathing should be kept steady during the examination to reduce the interference of diaphragm muscle movement on myocardial imaging. The person who installs the cardiac pacemaker should inform the doctor for reference in the image analysis. 3, whole body bone imaging: as much as possible to drink more than 500ml within 2 hours after the injection of imaging agents. Empty the urine before checking. If you have urine contaminated underwear or skin, you should wipe the skin and change your underwear before you can check it. If a metal prosthesis or a fake breast is implanted, the doctor should be informed of the implanted site. It is not advisable to check for barium meal, barium enema, etc. two days before the test. In order to prevent the expectorant from staying in the intestine, it affects the image observation. 4, glomerular filtration rate determination: as long as the first three days to stop diuretics, such as hydrochlorothiazide, furosemide and so on. Drink about 300ml of water in the first 30 minutes of the examination, and empty the urine when checking. 5, esophageal motor function imaging and gastric emptying measurement: patients should be fasted for 6-12 hours before the examination and according to the doctor's advice to stop atropine, Xintongding, Deshute, Dingshunning, cimetidine, famotidine Ding and gastric motility drugs, such as morphine, Pribos and so on. 6, thyroid imaging: according to doctor's advice to stop iodine-containing drugs and iodine-rich foods, such as kelp, seaweed, sea fish and shrimp, and stop thyroid tablets. Iodine contrast agents should be used for at least three weeks before examination. In the examination, if the child or the patient who is unable to cooperate, the sedative can be used before the examination. An analgesic can be used beforehand because the pain cannot be combined with the test. Metal objects worn on the parts to be inspected, such as jewelry, metal buttons, belts, keys, coins, etc., should be removed before inspection. Since most of the drugs used for ECT examination are excreted from the urine, it is possible to accelerate the discharge of the drug by drinking more water after the examination. Inspection process According to clinical requirements, there are static and dynamic imaging, planar and tomographic imaging, local and whole body imaging, and motion and resting imaging. Not suitable for the crowd Generally there are no people who are not suitable. Adverse reactions and risks Generally no adverse reactions.
