What are the balck spots that shows up on x-rays?

I had some x-rays done of my chest and my ribs and I noticed when I got home that there is black spots on them and I was wondering what they could be. Someone told me possible air pockets or something but there is alot of them and I didnt know what this might be.

When looking at the lungs, its the white spots that should be looked closely at. Air in the lungs shows as dark areas and is quite normal. Let the Rads diagnose the images as they have the training and experience to do so. Don't worry about it.

Black spots is a vague description....
Air does show up black on X-RAYS in the lungs, stomach and in the bowel.

Also sometimes the process of developing the films can leave some spots on the films.... .These are easily recognized by a professional but I could see it easily confusing the lay person.
Also if you have the X-Rays with you chances are they are copies which aren't as good quality as the originals.

Don't worry and quit trying to read your own films you'll only upset yourself..

When looking at X-ray images, you have to think of them like a "negative" of a photograph. Things that show up dark or black are things that the Xrays penetrated through, or in other words, things that are not dense, such as air. Things that are lighter or white in color are tissues that have density, such as bone, muscle, or fat. The more dense a tissue is, the whiter it looks, so bone is really white on an x-ray, while muscle tissues show up gray.
When you had your chest and ribs imaged, the technologist probably told you to "take in a deep breath and hold it." This filled your lungs up with air, which would show up as black areas on the X-ray. The overall black portion of a chest image is the lung field. Inside the lung field, you will see "lung markings," which are the tissues of the lungs themselves, through which the air passes as it is used by the body. Lung markings are the lighter areas of lines or patches that should appear, from the frontal view, sort of symmetrical on each side of the spine, inside the lung field. Also in the lung field, you will notice horizontal lighter lines, which represent your ribs. The radiologist who reads your images can tell a lot about your health by looking at your chest x-ray. They can measure your heart size, see your aorta and greater chest vessels, check for pneumonia and bronchitis (plus a whole host of other chest diseases), and even see signs of lung or bone cancer. They can also see the curvature of your thoracic spine, check for broken ribs, and maybe even see food and air in your stomach. The chest x-ray, when performed properly, can be one of the most effective diagnostic tests a physician can order.
If you have worries about your images that were not addressed by the doctor who ordered the test, you should follow up with your doctor after the radiologist has had a chance to read the images and send a report to the doctor's office.
Good luck and Feel better!!
