[ Development of China's pharmaceutical network technology] With the development of X-ray imaging technology, the visualization of digital medical imaging equipment DR - dynamic DR, X-ray barium meal inspection technology has been upgraded in the accurate diagnosis of digestive tract diseases. So, what are the advantages of dynamic DR compared to other inspection equipment?
X-ray barium angiography (oral and enema) examination, divided into conventional esophagography, upper gastrointestinal angiography, and total gastrointestinal angiography. Conventional esophagography is suitable for the diagnosis of esophageal tumors, diverticulum, varicose veins, foreign bodies, inflammation, lesions of adjacent esophageal organs such as heart, aorta, mediastinum and the like. Esophageal hypotension double contrast angiography is suitable for early detection of esophageal tumors, inflammation, diverticulum and routine angiography. Conventional upper gastrointestinal angiography is suitable for any upper abdominal discomfort and gastrointestinal symptoms; suspected pancreatic cysts and pancreatic head cancer and other diagnostic tests. Gastric and duodenal hypotonic double contrast angiography is suitable for early gastric cancer, pancreatic head cancer, duodenal cancer and cholangiocarcinoma, and examination of suspicious cases of common gastrointestinal tract. Total gastrointestinal angiography is suitable for congenital dysplasia; chronic non-specific inflammation and tuberculosis examination of benign and malignant tumors of the digestive tract; observation of intestinal parenteral lesions and intestinal relationship, postoperative functional observation. Colonic enema is suitable for colonic tumor, polyp, granulomatous lesions, localized enteritis; ulcerative colitis; megacolon; diagnosis of colonic intussusception.
With the development of X-ray imaging technology, the emergence of visual DR-dynamic DR has enabled X-ray barium meal inspection technology to improve the precision diagnosis of digestive tract diseases.
The advantages of dynamic DR in digestive medicine are mainly reflected in the following aspects:
Dynamic DR imaging has a large format: 17×17 inches, which can be completed in one exposure for a wide range of imaging sites such as esophagus, stomach, small intestine, colon, etc., greatly reducing the radiation dose of patients;
Dynamic DR image clarity: Compared to traditional gastrointestinal machines (image intensifiers), spatial resolution can be increased by one to two times, and image quality is significantly improved;
Millisecond-level dynamic and static switching: In the perspective process, real-time spotting can realize millisecond-level dynamic and static image switching, especially in esophageal angiography, and quickly capture images of lesions;
Video save, real-time playback: with video save playback function, after the patient check is over, the patient can still be diagnosed by video playback, no need to repeat the check.
The following two cases are typical of using dynamic DR diagnosis to be more advantageous than other diagnostic methods.
1. Esophageal achalasia
Axillary achalasia, also known as sputum sputum, giant esophagus, is due to esophageal dysfunction caused by neuromuscular dysfunction of esophageal and stenosis, causing insufficiency of the lower esophageal sphincter, food can not pass smoothly and stay, thus gradually reducing esophageal tension and peristalsis And a disease of esophageal dilation.
Its main features are the lack of peristalsis of the esophagus, the lower esophageal sphincter (LES) high pressure and the relaxation response to swallowing action.
Then, the routine diagnosis of gastroenterology is generally based on the following measures:
1, preferred esophagography or upper gastrointestinal angiography;
2, the esophageal external pressure measurement;
3, gastroscopy (lower esophagus and cardia do not consider gastroscopy);
When the human body encounters esophageal dysfunction, it is extremely uncomfortable. At this time, it is difficult to swallow and the eating adverse reaction is severe. Then, the dynamic DR has the best choice for the department. Different from the usual digital gastrointestinal machine, the visualized large format and rapid imaging of the dynamic DR will minimize the time for the patient to endure the pain and improve the doctor. The efficiency of correct diagnosis. Moreover, in this case, when the hospital performs the clinical route selection, it is necessary to refer to the contrast image obtained by the contrast to determine the implementation of the next treatment plan. Compared with external pressure test, the diagnosis result of dynamic DR is more objective; compared with gastroscopy, dynamic DR can reduce the possibility of damage to the esophagus, reduce the frequency of esophageal reflux and provide the most direct and reliable first line for clinical practice. Diagnostic information, three things!
Second, ulcerative colitis
Ulcerative colitis is a chronic non-specific inflammatory disease of the colon and rectum that is not well understood. The lesion is confined to the large intestine mucosa and submucosa. Most of the lesions are located in the sigmoid colon and rectum, and can also extend to the descending colon, or even the entire colon. The course of the disease is long and often recurrent. The disease is seen at any age, but it is most common in 20 to 30 years old.
In this case, the routine examination of the Department of Gastroenterology generally considers the following measures:
1, colonoscopy;
2. Barium enema angiography;
Through analysis, colonoscopy as a common means of colitis often has to be applied under the premise of patient's informed reaction, and its side effects are often much larger than barium enema, especially in colonic mucosa. In severe cases, the use of colonoscopy often causes greater suffering to patients.
In contrast, barium enema angiography in dynamic DR applications often detects the corresponding colonic disease at the expense of minimal pain. This type of examination often adapts to most patients who come to see a doctor and can effectively prevent intestinal diseases. Perforation possible.
In summary, the above case analysis is not difficult to reflect the clinical application of dynamic DR in digestive medicine. Compared with other inspection methods, it has clear imaging, convenient application, small side effects, flexible application of multi-position, multi-axis position and dynamic shooting. The range of advantageous observation applications. And it can clearly show the local and overall appearance of the digestive system organs, and reveal the relevant morphological and functional changes of the digestive system. At present, the dynamic DR in the clinical application of digestive medicine is also constantly pursuing breakthroughs, effectively combining traditional X-ray inspection methods and the technological application of updated X-ray equipment. In my opinion, dynamic DR, in the future, can do better. !
Dynamic DR makes the diagnosis of digestive diseases more accurate
Dynamic DR, a digital medical imaging device that has been popular in the medical device circle in recent years, is a large-scale digital medical device that is popular in mainstream radiology diagnosis in major departments. At present, the clinical diagnosis of digestive diseases, X-ray examination of dynamic DR applications is still the preferred medical imaging technology. Although there are other advanced imaging techniques, such as CT, MRI and ultrasound, which show great advantages, X-ray examination has an irreplaceable clinical advantage in certain diseases. Although endoscopy has been hailed as the "gold standard" for the diagnosis of gastrointestinal mucosal diseases, it is a traumatic examination for patients, especially for middle-aged and young children. Ultrasound can not detect early gastric cancer. It is not sensitive to the small symptoms in the stomach, so the X-ray barium meal examination is the most suitable method for the examination of digestive diseases in a special population. X-ray barium angiography (oral and enema) examination, divided into conventional esophagography, upper gastrointestinal angiography, and total gastrointestinal angiography. Conventional esophagography is suitable for the diagnosis of esophageal tumors, diverticulum, varicose veins, foreign bodies, inflammation, lesions of adjacent esophageal organs such as heart, aorta, mediastinum and the like. Esophageal hypotension double contrast angiography is suitable for early detection of esophageal tumors, inflammation, diverticulum and routine angiography. Conventional upper gastrointestinal angiography is suitable for any upper abdominal discomfort and gastrointestinal symptoms; suspected pancreatic cysts and pancreatic head cancer and other diagnostic tests. Gastric and duodenal hypotonic double contrast angiography is suitable for early gastric cancer, pancreatic head cancer, duodenal cancer and cholangiocarcinoma, and examination of suspicious cases of common gastrointestinal tract. Total gastrointestinal angiography is suitable for congenital dysplasia; chronic non-specific inflammation and tuberculosis examination of benign and malignant tumors of the digestive tract; observation of intestinal parenteral lesions and intestinal relationship, postoperative functional observation. Colonic enema is suitable for colonic tumor, polyp, granulomatous lesions, localized enteritis; ulcerative colitis; megacolon; diagnosis of colonic intussusception.
