Digestive system of ordinary X-ray examination of tumor

By | April 5, 2012

Ordinary X-ray examination of digestive system tumors: the use of X-ray diagnosis of diseases has been nearly a hundred years of history, in the clinical application of a wide range of subjects, the diagnosis of tumor disease has played a huge role, and has accumulated rich experience. Ordinary X-ray examination at present is still the basic clinical, the most common means of inspection.
Since the digestive system including the esophagus, stomach, intestine and liver, gallbladder, film organs, and between them and their lack of natural contrast between the adjacent organs, so most of the necessary imaging to imaging. Gastrointestinal imaging contrast agents used in the lock of sulfuric acid, and liver and gallbladder film imaging contrast agents used for the biliary meglumine plastic, rubber, etc. meglumine. Esophageal cancer are described below:
Most of the malignant neoplasms that cancer, the vast majority occurred in the esophagus mucosa, a small number of sources in the embryo leaves sarcoma, sarcoma is more common in leiomyosarcoma, followed by well fibrosarcoma, liposarcoma and so on. Is a rare benign tumor of the esophagus, leiomyoma is more common, followed by still fibrous tumor, muscle fatty tumors, hemangiomas. X-ray findings of benign tumors is generally similar to the filling defect, edge smooth, mostly round or oval rules, food wall soft, flexible, able to expand and contract, most of the Dayton agent by not blocked.
Esophageal cancer is a common malignancy, x ray dam meal examination is the most easiest and most common and effective method. Multi-axis points through the film with digital perspective can be found early esophageal cancer, for patients with advanced lesions can be determined, the scope of violations, cancer type, and estimated the rate of surgical resection and prognosis of patients, and can observe the results of various treatments.
Ordinary X-ray of digestive system tumors 1. Early X-ray transformation in esophageal cancer
Can be divided into flat, protruded and depressed type. Flat per flat cancer stem, along the esophageal wall invasion, the limitations of esophageal wall stiffness, showed a small esophageal granular change or disorder of the network structure. Esophageal lumen protruding tumor growth to uplift, expressed as plaque or papillary uplift, central ulcer may have formed. Lian depressed the cancer has rotten, ulcer occurred, showing depression change. Irregular lateral to the jagged, irregular orthotopic lock pool, there are granular nodules, were map-like changes, clear edge.
Ordinary X-ray of digestive system tumors 2. In X-ray changes with advanced esophageal cancer
(1) medullary type: on-chip in the esophagus appears as irregular filling defect, the upper and lower edge of the boundary with the normal esophagus was sloping, narrow lumen. Mucosal lesion damage, the common sizes Xin Ying.
(2) Grass umbrella: on-chip display significant in esophageal filling defect, the upper and lower curved edge, the edge sharp, clear boundaries with the normal esophagus. Mucosal lesion pattern interrupt, Dayton agent by some obstruction phenomenon.
(3) ulcerative type: on-chip display larger in esophageal Xin Ying, Xin see the impact on the tangential position in depth within the esophagus and even prominent in the lumen contours outside. Such as the ulcer edge of the uplift, see "Half Moon sign." Obstruction of the passage of the lock agent is not obvious.
(4) narrowing the type: short esophageal lesions, often in the 3cm below the edge of smooth, local mucosal pattern disappeared. Agents through the locks when the obstruction is more serious lesions dilated upper esophagus, showing a ring or funnel-shaped stenosis.
(5) cavity type: lumen widened esophageal lesions, often has fusiform expansion, there are irregular or polypoid filling defect, the lesion more clearly the edge of the upper and lower hook sharp, and sometimes that edge, Dayton agent through the fair. Advanced esophageal cancer with medullary type is most common, followed by heavy umbrella, the other various types of rare. Often the formation of advanced esophageal cancer esophageal tracheal thin. Visible contrast agent into the appropriate bronchus, so that development.
