My name is 64-row volumetric CT machine from General Electric, the most advanced CT machine in the world since the birth of the family more than 30 years ago, is the “newest” in the family. Compared with those CT machines in the past, what are the advantages of 64-row volume CT machine? (1) The examination is fast, so fast that CC can capture the image of dynamic organs, such as 5 seconds to complete the high-resolution scan of the non-stop beating heart, 15CC17 seconds to complete the whole body of the patient (1.75 meters tall) high-resolution data acquisition; (2) The examination is fine, and can scan the tissue 0.625mm thickness; (3) The patient receives much less radiation and contrast agent than before much less radiation and contrast agents than before, and at the same cost as before. This is the contribution of high technology to mankind. There are many things that 64-row volumetric CT can do, mainly in the following areas: 1. Non-invasive, rapid screening for early coronary heart disease This is one of my most outstanding capabilities. When you lie down on the examination bed, the doctor injects contrast from inside the vein and then quickly spiral scans and acquires data from the heart and coronary arteries, and then reconstructs images of both. It takes less than 5 seconds to: (1) Clearly display the coronary arteries like a tree, diagnose coronary artery stenosis, atherosclerosis and calcification, and assess the efficacy of intracoronary stenting and post-bypass surgery, making it an ideal, non-invasive test for screening for coronary heart disease. (2) Comprehensive analysis and evaluation of heart surface morphology, valve structure, myocardial thickness, myocardial perfusion, left ventricular ejection fraction, cardiac output per beat, volume of the heart, motion of the heart and valves, and ventricular wall motion; 2. Detection and diagnosis of vascular lesions in various parts of the body This is also an advantage I have over those previous CT machines. After the rapid injection of contrast from the vein, it can show the vascular lesions in the head and neck and extremities, chest and abdomen and other internal organs clearly, such as hemangioma, vascular malformation, stenosis or embolic lesions in the head and neck; large artery aneurysm, large and middle artery inflammation or stenosis; pulmonary artery embolism and dilatation; lung segment isolation; arteriovenous imaging before and after liver transplantation; renal artery, renal pelvis and ureteral lesions; venous thrombosis, etc. immediately The examination can be done immediately. Detection and diagnosis of vascular lesions in various parts of the body. Perfusion scan imaging of organs Differential diagnosis of cerebral hemorrhage, cerebral embolism, brain tumor, benign and malignant tumors of other organs such as liver and lung, etc. 4.Colon imaging can provide high-quality images of colon mucosa and contour, observe the appearance of colon and luminal mucosal changes, and be used for the diagnosis of tumor, polyps, intestinal entrapment, intestinal obstruction, intestinal torsion, ulcerative colitis, etc. 5.Simulation endoscopy CT simulation endoscopy is a special endoscope that converts the three-dimensional volume data obtained from spiral scan into a special endoscope that imitates the observation mode of optical fiber endoscope by computer, and almost All lumen organs (gastrointestinal tract, blood vessels, trachea, spinal canal, otorhinolaryngopharyngeal cavity, bladder, etc.) can be simulated endoscopic display. The examination method is simple and easy to perform without intubation and without any discomfort, and is an important complementary examination to fiberoptic endoscopy. It can be used for the examination of gastrointestinal tumors, polyps, obstruction, inflammation, ulcers, tracheobronchial tumors, nasopharyngeal cavity tumors, paranasal sinusitis, vocal cord polyps, middle ear malformations, spinal stenosis, bladder tumors, polyps, and intravascular lesions.
