Medical network - on March 15, in recent years, the incidence of lung cancer increased. According to statistics, 2015, 2015 new cancer cases worldwide, 8.2 million people died of cancer, is expected to increase over the next 20 years new were 70%. Due to an ageing population, bad living habits, environmental pollution and the traditional methods to cure rate low, our country has become a great nation of cancer morbidity and mortality. According to the national cancer registry statistics show that China with 4.2916 million new cases of cancer in 2015, 2.8142 million cases of death. High on morbidity and mortality of lung cancer and stomach cancer. Both incidence and mortality, lung cancer were malignant tumour in the first place.
2015 cancer deaths in China (one thousand) and accounted for
Lung cancer survival rates highly correlated with the first stage of diagnosis of the disease. Unfortunately, lung cancer is the lowest overall five-year survival rate is almost in all types of cancer types of cancer is only 17%. As confirmed in the early stage, the five-year survival rate will increase significantly. Therefore, early diagnosis of lung cancer and effective screening can save a lot of patient's life, is the key to the current efforts to prevent and deal with lung cancer.
Using X-ray imaging screening is the most commonly used at present, the most direct means of screening, in most areas of China, X-ray chest X-ray examination is the key to the lung cancer screening, how accurate screening out the suspected focal point become the pursuit of better DR equipment. Past, as it were, DR single check way already could not satisfy the present domestic development trend of lung cancer, because the chest bump easy hiding place in the spine, ribs, heart, lung door side cover, etc., near a single chest X-ray photography easy omission focal point, use a piece of functionality does not have visual point of early lung cancer screening, DR equipment can let a person worry.
The following case is that, due to a lack of visual point function, a single chest X-ray photography screening can't immediately give accurate diagnosis, after repeated misdiagnosis for patients and their families left behind is endless regret.
Case 1:
In the third year of the second year of the first year
Case analysis:
In this case, the patient in a single chest X-ray examination, diagnosing upper left lung nodules shadow with high density, the first two in the X-ray angiography diagnosis results unscathed. Separated by a year to review was misdiagnosed as "scleroma tuberculosis stove", and treatment for this. But, in the third year after diagnosis find nodular shadows are increased again, after was diagnosed with lung cancer, but it is too late. Such as using a visualization point function of DR equipment, chest X-ray and chest X-ray seamless combination, under the perspective of "high density nodular shadows" all-round, multi-angle, high count for more confirmed information, further pathological analysis, diagnosis results, the first time do early discovery, early treatment, the result will be very different.
Case 2:
Figure 2 overlapping left collar bone density nodules, mistaken for clothes buttons, pathological lung adenocarcinoma
Case analysis:
The case occurred in a domestic basic-level hospitals, patients first screening through the X-ray photography, shows in the left upper lung field with high density oval nodules, due to the shape and buttons, buttons for clothes, did not do further diagnosis. To review again after the second year, patient, nodular shadows, only to find that the photograph immediately further diagnostic work-up, finally after biopsy confirmed for lung cancer, missed the best period of treatment.
Similar clinical cases abound. In our country, especially in the secondary and the following in the hospital with a large order of magnitude, due to the backward medical equipment, human resources and the limitation of professional and technical level, there are many because of the X-ray photography screening can't immediately give accurate diagnosis, missed the best period lung cancer treatment, led to the current domestic detection of lung cancer, more than 87% for the medium and late patients, the cure rate at lower levels for years. With the convening of the 2017 national two sessions, "medical reform" again "accurate diagnosis" as the core of the national people's most concerned problems, how to improve the detection rate of early lung cancer, do early diagnosis and early treatment thorny problem for the inhibition of lung cancer.
Choice of X-ray screening for lung cancer screening, often divided into two chest X-ray and chest X-ray examination way, each has advantages and disadvantages. The X-ray examination is the advantage of the image is clear, better contrast, can have permanent record, for review contrast, consultation discussion, defect is not watching the movement of activities organs and bones, blind area; And the advantage of chest X-ray is by turning the patient position, a multi-angle observation, and watching the movement of internal organs, doctors can by chest X-ray, multi-dimensional dynamic observation in order to help diagnosis to lesions, defect is insufficient resolution, low contrast. According to the above comparison shows that the deficiency of the advantage of chest X-ray is chest radiograph, and chest radiograph advantages disadvantages, only the two complement each other, cooperate to use, can give full play to its precise diagnostic utility. Throughout the world DR equipment technology development, DR visualize some piece of technology is one of the best combination of both advantages, realize the X-ray in chest X-ray, can be said to be the choice of lung cancer screening equipment, such as continue using a single chest X-ray or chest X-ray, DR does not have visual point function, lung cancer screening lets a person worry! |
