MRI scans, X-rays, and tomography are all imaging techniques used to visualize structures within the body, including bones. X-rays are particularly effective for viewing bone structures, as they highlight differences in density. MRI scans provide detailed images of soft tissues but can also show bone marrow and joint conditions. Tomography, including CT scans, offers cross-sectional images that allow for a comprehensive view of both bones and surrounding tissues.
Xrays and CT scans
Usually to check for broken bones or bone malformations.
Yes, that's why it is used to tell where bones are. The x-rays pass through the tissues like muscles and fat but are stopped by the bones.
no they do not have bones, just a big wormy body full of muscles.nnnnnnnnnnnnnnnnnnnnnnnnoooooooooooooooooooooooooooooooooooo ^actually this is incorrect. worms do in fact have bones thats why they show up on xrays looking like dragons
yeah because it can break the bones so wheb your next in hospital, do not get x-rayed
X-rays can penetrate the body and are absorbed differently by different tissues. Dense tissues like bones absorb more x-rays and appear white on the image, while softer tissues absorb fewer x-rays and appear gray. This contrast helps to visualize internal structures like bones, organs, and foreign objects inside the body.
Chicken gave the black persons a coupon.
No, they do not.
no no no
no
A cat scan or CT scan (same thing) shows doctors a slice of the bodies insides, it is good for diagnosing problems with bones and soft organs like liver, bowel, spleen, and pancreas. Plain xrays only show bones and its 2 dimensional. MRIs are good for muscles and tissues like tendons.
Bones always appear as white images in regular xrays. However they arent really white because the film is clear, the plastic on the view box is white. But on xray film it is coated with a metalic layer. The xrays make the metalic layer stick to the film. So the black part of the film is where all the xrays reach the film. If the area on the xray is gray, then that means that some of the xrays are getting through implying that the structure is more dense than the black part. Soft tissue appears gray. The bone is a very dense structure allowing minimal to no xrays getting through. The film is then put through the processor and the film runs through chemicals that make the picture "stay" on the film. It is then rinsed and dried. Since the xrays make the metalic layer stick, none stick to the area of the bone because no radiation got through and the layer was washed off during processing. This is why bones appear white, they are the densest structure.
