Lung cancer, also known as Lung cancer, is one of the most common malignancies, with a significant increase in Lung cancer incidence and mortality in recent decades.
Lung cancer (lung cancer) has become the leading cause of cancer death in mankind, and have the lung cancer and AIDS experts say is related to the century with the bad habits of two of the most serious harm human health disease. Lung cancer has become the most common cause of death among malignant tumors in 28 developed countries. It is suggested that the incidence of lung cancer in China will show a significant increase over a long period of time.
Primary bronchial lung cancer (tumor) is the most common primary malignancy of the lung. Lung cancer in at least 35 countries in the world is the first leading cause of cancer deaths in women, second only to breast cancer deaths in women. The disease is more than 40 years old, and the peak age is between 60 and 79 years old. The prevalence of men and women is 2.3:1. Race, family history and smoking had an impact on lung cancer. Lung cancer is the fourth most common malignancy in men and the fifth among women.
Dynamic DR check case
Patient: wu so-and-so, male, 54 years old
History: inguinal hernia in hospital surgery, no respiratory symptoms, preoperative DR chest film, X-ray suggests in the left lung ueno limitations with higher density, and on the left side of the sternoclavicular joints and calcification of the first rib cartilage shadow overlap. It is difficult to determine where the lesion is, and it is easy to miss. When asked about the medical history, the patient was in a local health hospital three months ago to take a chest X-ray (the local health hospital used regular X-ray machines).
In our hospital, we used DR dynamic fluoroscopy to observe: to clarify the lobular lesion of the left lung, the imaging diagnosis of our hospital was lung cancer, and the next day, the patient went to the hospital of the city hospital to confirm the diagnosis of lung cancer on the left.
Dynamic DR check analysis
Figure 1: positive chest chart 2: dynamic DR
For inguinal hernia patients admitted to hospital, no respiratory symptoms, DR chest film inspection before surgery, X-ray suggests in the left lung ueno limitations with higher density, and on the left side of the sternoclavicular joints and calcification of the first rib cartilage shadow overlap. Because it is difficult to determine the lesion of the chest piece, it is impossible to diagnose accurately and even miss the diagnosis. In order to ensure that can determine the disease, accurate diagnosis, we adopt dynamic DR perspective to observe the function, through the perspective of observation: in the process of clear the left upper lobe 39 x32 ㎡ spherical lobulated lesions, and high count, under the perspective for diagnosis. The imaging of our hospital considers pulmonary tumor and recommends CT scan. The next day, the patient went to the city hospital for CT enhancement scan, which was diagnosed as left lung cancer. And to be hospitalized in time.
After the diagnosis, the patient was asked about the history of the patient, who had not seen an abnormality in the chest film at the local health hospital three months ago (the local health care department used a regular X-ray machine).
Application of dynamic DR in lung cancer screening
Lung anatomical position is located in the chest cavity, on both sides of the mediastinum, the left heart, and be ribs package, in the X-ray image, small lesions are easy to be covering ribs, heart shadow image, especially difficult to under the chest radiograph diagnosed early lung cancer. Dynamic DR has the function of visualizing operation, so it can observe the multi-angle in perspective and can accurately locate small lesions and avoid missed misdiagnosis. In conventional images, especially lung tumors and nodules, it is easy to miss out due to the overlap of images and the inexperience of doctors. Therefore, the visual operation of dynamic DR and the function of high inventory feature can solve such problems well, and achieve the aim of accurate diagnosis of lung cancer screening.
conclusion
The conventional DR piece is a two-dimensional image, especially the pleura, which is difficult to accurately diagnose because of the overlapping of the mediastinal heart and the overlapping part of the lower diaphragm. The above case shows that if it is only a static chest image, plus the lack of a doctor's experience, it is easy to miss the diagnosis. Using the dynamic DR visualization operation, it is possible to carry out high inventory and clear the lesion in the case of perspective, reduce the misdiagnosis and improve the accuracy of diagnosis.
