Specially sending fiber _'s general knowledge of diagnosis of lung
Diagnosis
(1) Diagnose technology
1,The image learns to check
(1)Regular the intersection of X-ray and the intersection of chest and slice take a photograph of slices of technology, must pay attention to, penetrate terms to be appropriate, employ intermediate to increase the sense to reject, focus should be small. Early alveolus inflammation can't reveal unusually on the X line; Up to the progress of pathological change, the X-ray demonstrates the cloud can see the small and point-like filling the air shade vaporifically and indistinctly, like rubing the glass. Develop, see fiber take, become obvious, knit form, knit form from very thin network to thick network further, or take the form of the network and weave the tubercle. Have bag not of uniform size that changes even more in later period, namely honeycomb lung. The lung volume shrinks, lift on the skin of diaphragm, split and shift among the leaves.
(2)CT compares with the resolution ratio and is superior to the X-ray, employs and distinguishes CT (HRCT) high Can raise the intersection of space and resolution ratio further, diagnosis in IPF, especially early the intersection of alveolus and inflammation and fiber take distinguish and honeycomb discovery of lung extremely helpful.
(3)The intersection of nuclide and IPF have the intersection of alveolus and the intersection of capillary and the intersection of membrane and penetrating increase often. Nuclide technology sucks 99mTc-DTPA aerosol to determine the skin is penetrating (LEP) at the lung It is obvious T1/2 shortens, contributes to finding and diagnosing a quality pulmonary tuberculosis in early days, has no specificity as to IPF.
2,Lung the intersection of function and typical the intersection of lung and function to check IPF change, include person who restrain from keep in touch with damage, lung capacity dwindle and lung comply with sex reduce and diffusing capacity reduce. The serious one increases widely PaO2 decline and PA-aO2. Lung function check with image learning, contributing to, diagnosing especially sport test in image learning, having diffusing capacity reducing and hypoxemia disease promptly appearing unusually, in early days by technology. The lung function is checked and can be observed dynamically, it is very helpful to appraise the condition, it may be useful too to be used in the curative effect of the examination. Likewise, the lung function of IPF unusually has no specificity, there is no value of differential diagnosis.
3,The bronchus alveolus irritates and washes to retrieve the total number of liquid cells to increase, and the increase of neutral cell proportions is IPF more typical change, to diagnosing helpfully. Still used mainly for studying at present.
4,It examine IPF livingly lung early, change characteristics certain at the histologies of middle period,and among it is a lot of including a lot of that there is cause of disease person who can seeks clear in cause of disease quality pulmonary tuberculosis, so lung live examine to the intersection of disease and make a definite diagnosis of and active the intersection of appraisal and very much inclined justice this. First choose to employ finely to prop up the mirror and make TBLB, but the sample is small, diagnoses that there is the fashion that has difficulty in. Should cut open the chest and live and examine if necessary.
