Chest Xray (how to read Chest Xray)

ok so in chest xray always follow the following sequence for descrption:
1. patient information
2. postioning PA, AP, Lateral
3. describe the position of trachea.
4. talk about the heart and its appearance.
5. talk about the lungs and there appearance
6. talk about the diaphragm
7. then describe the appearance of the bones and the surrounding soft tissue and fats.

Remember that a pathology will always be discussed first.

Now an example:
This is the chest Xray of a 40 year old female mehreen, the Xray shows a PA view. on the radiograph the left lung of the patient appears normal whereas the right lung contains a radio-opaque region in the middle zone (2nd to 4th rib), this radio-opaque region also has a few small radiolucent regions in it thus giving the appearance of an air bronchogram, more over the lateral CP angle on the right side is not obliterated, all these finding are consistent with the diagnosis of pneumonia.
The trachea of the patient seems normal and has no deviations, the left and right borders of the heart appear normal and the ratio of transverse diameter of heart to the transverse internal diameter of the thorax at the level of the diaphragm is 2:1 ( measure this before you quote), the right hemidighragm is positioned higher than the left hemidiaphragm because of the presence of liver the weight of heart. thus diaphragm is normal. no hiatal herniations can be seen. The gastric bubble is visible which suggestive that the patient was in an erect position. The spine, scapula, clavicles, femoral heads, sternum and ribs appear normal. The soft tissue and fat appear normal and no surgical emphysema is seen.
