Questions and answers:
1 and x-ray manifestations of left atrial enlargement
A:
(1) Four-arch sign or four-arch sign can be seen at the left cardiac margin of the posterior anterior position.
(2) Double atrial shadow or double arc shadow can be seen at the right heart margin in the posteroanterior position.
(3) Right anterior oblique position, the impression of esophageal atrium deepened and even retreated.
(4) The left main bronchus is elevated in the left anterior oblique position.
2. Advantages and disadvantages of X-ray fluoroscopy and photographic examination.
A:
(1) perspective can observe candidates dynamically, continuously and from multiple angles.
(2)X-ray imaging is clearer than fluorescence imaging.
(3)X-ray imaging images can be permanently recorded on film for easy review and comparison.
(4) The perspective inspection is simple, convenient and economical, which is convenient for general survey.
3. X-ray manifestations of simple mitral stenosis?
First, the heart is enlarged, the left atrium and right ventricle are enlarged, and the left atrial appendage is often obviously enlarged.
Second, general aortic ball contraction.
Third, the left ventricle contracts, the apex moves up, and the lower part of the left margin of the heart is relatively straight.
Fourthly, mitral valve calcification is a direct sign.
Five, pulmonary congestion or interstitial edema, upper pulmonary vein dilatation, lower pulmonary vein thinning. Sometimes fine granular shadows with a diameter of 1 ~ 2mm can be seen in the lung field, which is hemosiderosis.
4. What are the direct and indirect X-ray signs of bronchogenic carcinoma (central type)?
