Safety Concerns
Maybe you're concerned about the long-term impact of having all your atoms
mixed about, but once you're out of the magnetic field, your body and its
chemistry return to normal. There are no known biological hazards to humans
from being exposed to magnetic fields of the strength used in medical imaging
today.
How
MRI Works
What
Is Ultrasound
Ultrasound
(US) imaging, also called ultrasound scanning or sonography, is a method of
obtaining images from inside the human body through the use of high frequency
sound waves. The reflected sound wave echoes are recorded and displayed as
a real-time visual image. Ionizing radiation (x-rays) are not involved in
ultrasound imaging.
Ultrasound
is a useful examination tool for many of the body's internal organs, including
the heart, liver, gallbladder, spleen, pancreas, kidneys, and bladder. Because
ultrasound images are captured in real-time, they can show movement of internal
tissues and organs, and enable physicians to see blood flow and heart valve
functions.
How
MRI Works -
MRI
scanners vary in size and shape, and some newer models have a greater degree
of openness around the sides. Still, the basic design is the same, and the
patient is pushed into a tube that's only about 24 inches (60 centimeters)
in diameter. But what's in there?

Safety Concerns -
The
biggest and most important component of an MRI system is the magnet. There
is a horizontal tube -- the same one the patient enters -- running through
the magnet from front to back. This tube is known as the bore. But this isn't
just any magnet -- we're dealing with an incredibly strong system here, one
capable of producing a large, stable magnetic field.
