X-rays use what are called X-rays...that was a given but MRIs use magnetic pulses instead of the X-rays. The difference is that the X-rays don't pass through bone (so you see the bone) and the magnetic pulses penetrate the entire flesh but bounce off every cell. This shows what the inside of the person looks like.

What is the difference between a chiropractor and a radiologist?
chiropractors perform vertebral and extremity adjustments. radiologists deal with medical imaging stuff like xrays and ultrasounds
Which medical imaging technique depends on the use of xrays moving in an arc around the body producing a cross sectional image?
Magnetic Regonance Imaging (MRI)
What is the difference in Umbra and Penumbra in Xrays?
Penumbra is the excess fog from scatter radiation
Mri and xrays what is the preference of most people?
It's not really a personal preference kind of thing, although older MRI machines, because of their cave-like shape, are tough on claustrophobes. Xray machines are an order of magnitude less expensive (at least) and require a lot less maintenance, so usually, if you're to receive an MRI, they'll at least look to see if an xray reveals the problem. Xrays reveal details of bony processes and other dense materials really well, but don't do nearly as well with soft tissues. MRI's can give very detailed views of soft tissues, which can every be applied to 3d and 4d imagery. On the other hand -- as I said -- MRI machines are pricey. Also, in trauma's MRI's require electromagnetic isolation, which means a special room for them. Also, metals, particularly ferric metals, need to be kept away from the machine. This makes MRI usage difficlut in acute traumas.
Are there certain tests a doctor can do to see if you have bone disease?
Yes, they can perform blood tests, xrays, CAT Scans, MRI. Bone density test. They might also do a bone marrow test.
What is the difference between CT and MRI images from a physician's point of view for example the appearance of different tissues?
CT suited for detecting cancers, viewing bone injuries, diagnosing lung and chest problems.MRI is suited for examining brain tumors, spinal cord injuries, soft tissue in ligament and tendon injuries,-CT Provides good details about bony structures. MRI Less detailed compared to X-ray-CT Good soft tissue differentiation especially with intravenous contrast. Higher imaging resolution. MRI is better at telling the difference between different soft tissues and between normal and abnormal soft tissue-CT scan is faster than MRI.-effective radiation dose from CT ranges from 2 to 10 mSv. No Radiation for MRI-CT can pose the risk of irradiation. Not the case of MRI
Is there a difference in an brain MRI of a gay person?
No they function the same as the rest.
What is the difference between a surgery and a procedure?
Any type of surgery is a procedure, a procedure for example can be a EKG, or a MRI, or a endoscopy. When you go into the hospital and whatever tests they perform is a procedure.
Do MRI scanners have any adverse effects?
MRI scanners have practically no adverse effects. MRI or magnetic resonance imaging works by noting difference of various images created by varying response of different body tissues.
When should MRI's not be used?
MRI scanning should not be used when there is the potential for an interaction between the strong MRI magnetic field and metal objects that might be imbedded in a patient's body.
