1、 What is Revolution CT

GE Revolution CT, equipped with 256 row gemstone detectors, abbreviated as 256 row CT, integrates cutting-edge technology in the CT field into one machine, creating technological advantages in CT coverage, speed, image quality, low radiation dose, energy spectrum, and scanning comfort. It has established new standards for imaging and low-dose screening of diseases such as respiratory system, urology, cardiovascular system, nerves, tumors, and orthopedics, improving medical efficiency and patient experience, Effectively assist doctors in accurate diagnosis and addressing critical illness challenges. It can be called the "aircraft carrier of the CT industry" and the leader in the development of the CT industry.

According to a survey, in 2013, RSNA released a revolutionary CT (RevolutionCT) that unified the three cutting-edge technological directions of "wide body, fast, and spectral". RevolutionCT also made significant breakthroughs in low-dose iterative reconstruction technology.

2、 The advantages of Revolution CT

1. New Element Gem Detector

The gemstone material detector of Revolution CT is the first brand new detector material in the industry in 20 years, and its data reception speed is 100 times faster than traditional detector materials, and its clearing speed is 8 times faster than traditional detector materials. Further improved image quality and measurement accuracy.

2. Extreme Speed Instantaneous Cut High Voltage Launch System

The high-speed transient high voltage generation system can complete an instantaneous switching and scanning of high and low voltage within 0.25ms, achieving simultaneity, homology, and directionality of 80kV and 140kV (the three same principles), ensuring the realization of cardiac and whole-body energy spectrum imaging in the original data space.

3. Third generation coronary artery motion tracking and freezing platform

The third-generation coronary artery motion tracking and freezing platform can record the trajectory, direction, and velocity of three high-speed moving coronary arteries throughout the entire process, compare them with standard coronary big data models, analyze and iteratively reconstruct the original data, thereby removing the artifacts of coronary artery motion and achieving high-definition imaging of the heart with natural heart rate.

4. Vick level precise spectral imaging

Microgram level precise energy spectrum scanning refers to the comprehensiveness, low dose, accuracy, and speed of energy spectrum applications. We have achieved low-dose, fast and accurate energy spectrum scanning of various parts of the body, including tumor imaging, vascular imaging, nervous system, respiratory system, urinary system, and skeletal system, enabling doctors to detect lesions earlier and perform qualitative and quantitative analysis.

3、 Indications for CT examination

1. Neurological disorders include traumatic brain injury, cerebral infarction, brain tumor, inflammation, degenerative diseases, congenital malformations, etc. It is the earliest applied human system, especially in the diagnosis of traumatic brain emergencies, which is a routine and preferred examination method. It can clearly display brain contusion and laceration, acute intracerebral hematoma, epidural and subdural hematoma, craniofacial bone fracture, intracranial metal foreign body, etc., and is more sensitive than any other method. CT diagnosis of acute cerebrovascular diseases such as hypertensive intracerebral hemorrhage, subarachnoid hemorrhage, cerebral aneurysm and arteriovenous malformation rupture bleeding, cerebral infarction, etc. has high value.

2. Cardiovascular system: available

2. Cardiovascular system: can be used for the diagnosis of pericardial tumors, pericardial effusion, etc. CT scan of acute aortic dissection has certain diagnostic significance, especially enhanced scan has characteristic manifestations and can be used for qualitative diagnosis.

3. Chest lesions: It has a very satisfactory effect on displaying lung lesions and has high diagnostic value for lung trauma, infectious lesions, tumors, and other homogeneous conditions. The display of tumors, lymph nodes, and pleural lesions in the mediastinum is also satisfactory, which can show the relationship between lung masses and the mediastinum.

4. Abdominal organs: Clear display of parenchymal organs such as liver, gallbladder, spleen, pancreas, kidney, adrenal gland, etc. It can clearly display the accurate anatomical location and degree of lesions for tumors, infections, and trauma, and has high value in disease staging. It is helpful for clinical treatment planning, especially for surgical positioning in the operating department, and has great diagnostic and differential diagnostic value for intra-abdominal masses.

5. Other: pelvic organ diseases, various bone and joint diseases, etc.

4、 CT examination precautions

1. Before the examination, a detailed medical history and various examination results must be informed to the CT doctor. If there are self saved X-ray, magnetic resonance imaging, and previous CT images, they must be submitted to the CT doctor for reference.

2. Remove clothing from the inspection area, including underwear and various items containing metal substances, such as headwear, hair clips, earrings, necklaces, jade pendants, coins, belts, and keys.

3. Those who need to undergo enhanced CT should fast for 4 hours before the examination.

4. To perform enhanced CT, it is necessary to explain to the doctor whether there is a history of drug allergies, whether there are allergic diseases such as liver and kidney dysfunction, asthma, urticaria, etc., and to have someone accompany and sign an informed consent form; Patients with diabetes need to stop taking metformin 2 days in advance.

5. CT enhanced scanning requires intravenous injection of contrast agent iodine allergy test, and can only be performed if there is no response after 20 minutes; After the examination, go to the observation room for 30 minutes to observe and leave without any discomfort or reaction; After the examination, it is necessary to drink more water to promote the excretion of contrast agent.

6. Do not take drugs containing heavy metals within one week and do not undergo gastrointestinal barium tests. Patients who have undergone barium examination must wait for the barium to be emptied; Those who are in a hurry to undergo CT examination should be given a clean enema or oral laxatives to clear the barium before undergoing CT examination.

7. During the examination, maintain a still position and cooperate with the examination to breathe calmly, hold your breath, not swallow saliva, and not blink your eyes; If there is any discomfort or abnormal situation during the examination, the doctor should be informed immediately.
