In recent years, medicine has been developing rapidly, and highly sophisticated examination techniques have brought gospel to mankind. In the past, when I was a medical student to diagnose cerebral infarction and hemorrhage and other brain diseases with the teacher to learn brain puncture, sometimes the patient to wear epileptic dull, still do not know what part of the brain in the disease. I do not know whether it is infarction or hemorrhage. Since the invention of CT and MRI, patients know the diagnosis and location of the disease without any pain. This is non-invasive diagnosis. In order to diagnose the disease, we try our best not to cause pain to the patient, which is non-invasive diagnosis. According to the experience of common non-invasive diagnosis, Henan Provincial People’s Hospital, Department of Traditional Chinese Medicine, Liu Junbao 1, for the diagnosis of gastro-esophageal small intestine, inserting the gastric tube is very difficult for all of us, and now the provincial hospital has introduced a foreign capsule gastroscopy like eating sugar from the anus at the end of the discharge, to the digestive tract down the whole picture, in fact, is a miniature camera. 2. 64 rows of CT can be given to the cardiovascular angiograms, the accuracy of up to 98 percent, but the patient painless, unlike the cardiovascular angiograms also to the heart inserted into the heart. Cardiovascular angiography also need to insert a tube into the heart, the patient like to experience a surgery. This non-invasive diagnostic cost is also cheaper than imaging 2 times. 3, 3.0 MRI cerebral angiography, renal angiography are cheaper than the real real angiography, the patient is painless. It can be predicted that soon endoscopy, both cystoscopy, hysteroscopy, can be replaced by sugar beans, sugar beans both micro camera. Medical science will bring happiness.
