Imaging Exam: Mri or magnetic resonance imaging is one of the more recently developed imaging modalities available to physicians. It uses powerful magnets to generate images. There is no ionizing radiation which is a major advantage over many other modalities. Mri is the best imaging exam that we have for most soft tissue and joint related problems. There are radiologists specifically trained in mri.
Dr. Jeffrey Wint

MRI means: Magnetic resonance imaging named for the effects of the strong magnetic field upon the atomic and molecular phase or spin and the image created when that magnetic field is altered and the excited particle changes gibing off a signal that is recorded and interpreted by a complex computer algorithm, resulting in an image.
Dr. Michael Gabor
Diagnostic Radiology 33 years experience
MRI: Magnetic resonance imaging, utilizes magnetic fields and radio frequency pulses "tuned" to specific molecules in order excite/relax those molecules, which results in an emission of a signal detected by the machine, and produces an image through an exceedingly complex computer algorithm.

An imaging procedure: Mri is an imaging procedure which provides the radiologist with detailed images of the body. The machine uses a very large magnet to help produce the images. There is no ionizing radiation. During the procedure, the machine will make many loud noises. Most patients choose to wear headphones and listen to music to avoid some of the noise.

My MRI show wedging to my d-10 and d-11 due to previous trauma. Can you explain what this means?

Dr. Chintan Sampat
Orthopedic Spine Surgery 18 years experience
A broken bone: Wedging of t10 and T11 is a change in the shape of the vertebral body part of the spine. The bone gets crushed from an injury and can change shape from its normal rectangular appearance to a more wedge shaped appearance. This can also be a normal finding from degeneration of the spine due to aging as well as due to genetic conditions such as scheurmann's disease.
