I have been struggling with trying to understand this concept. Thanks for helping me to finally understand!

The standard view of the chest is the posteroanterior radiograph, or "PA chest." Posteroanterior refers to the direction of the x-ray traversing the patient from posterior to anterior. This film is taken with the patient upright, in full inspiration (breathed in all the way), and the x-ray beam radiating horizontally 6 feet away from the film.

Fantastic video, explained perfectly.

BESTTTTTT EXPLICATIONNNNNN

Excellent videos, thank you sir.

The anteroposterior (AP) chest radiograph is obtained with the x-ray traversing the patient from anterior to posterior, usually obtained with a portable x-ray machine from very sick patients, those unable to stand, and infants. Because portable x-ray units tend to be less powerful than regular units, AP radiographs are generally taken at shorter distance from the film compared to PA radiographs. The farther away the x-ray source is from the film, the sharper and less magnified the image.

This is awesome. Great job!

Super helpful thanks!

Lifesaver thanks

Thank you. But how come in both PA and APthe heart is in the left side instead of right side for pa.

but how do each types come out? are the lungs depicted Left to right for both or just one

Thank you

Good explanation dude!

I have a question about technique. Why is it that when taking a PA and lateral CHX you use about 120 kvp with 5 to 10 mAs (on a wall bucky) but when doing a AP or portable you use about 85 kvp with __ mAs? Is it due to not using a grid with a portal/CR room?

شكراً جزيلاً

Since AP radiographs are taken from shorter distances, they appear more magnified and less sharp compared to standard PA films.

Step 1 in determining the technical quality..check the projection PA or AP ?

How much radiation is used getting a Chest X-ray (PA and Lateral).. getting surgery below the belt, Doctor has an order for this, I don't understand why.??

Super
