3d x ray scanning image
Chris
i need an image of the surface of my brain. an mri and a ct scan miss whats under the surface of your brain. the skull and brain are to close together and you cant see it. i think theres something maybe metal under my skull. can an x ray make your skull transparent? i need something like a normal x ray but see through. do you know how?
Answer
X ray have a penetrative power, with the quantity of the rays stopped being a function of the density of whatever it is going through, but it cannot change the property of matter.
Tomography allows a better view that allows a reconstruction of a 3D image by doing several X ray along different directions. Magnetic resonance imaging relies on the different way hydrogen in molecules will align with a powerful magnet, which allows it to image tissue that contain water.
The only imaging technique you have not listed is the positron emission tomography (PET) which require short lived radio active isotopes to be injected.
If those techniques do not work, then your request would need something that is not yet available.

What is the difference between a CT scan, an MRI, and a X-Ray?

(I don't know if it's a CT or a CAT scan) What is the difference between the three
Answer
CT and CAT are interchangeable. :) The differences between the 3 can get very involved, but can also be simple..
CT/CAT- These machines run off specialized xray technology that takes multiple, cross-sectioned images that are transferred to a computer and seen in a 3D model. The CT stands for computed tomography.
MRI - These machines run off powerful magnets, versus radiation - like X-rays and CT's. Magnetic Resonance Imaging is pretty neat because you actually get magnetized and the atoms in that area line up causing the nuclei in the area to become detectable by the machine. MRI's are often used for more detailed images, and are especially useful for examining different soft tissue organs like the brain, heart, etc. With certain dye injected contrast materials, radiologists are able to see veins or arteries as well.
Xray- These are commonly used for diagnostic purposes because they help show internal structure and can often help a doctor see abnormalities. Normally, a CT or MRI would be ordered if the radiologist needed to see more than what is showing on the Xray.
Xrays can be taken from portable machines, CT/MRI is traditionally done in a big machine where you lay down and the area of interest is scanned.
