The technology involved with MRI is that it uses magnetic fields and radio waves to make clear images vs. Ultrasound, where a sensor that is passed over the area of study. The most important part of the MRI scanner is the two magnets. How MRI works, a patient lies on a table inside of the cylinder while tests are then taken. The human adult body is made up about 60% of water, which is made up of hydrogen and oxygen atoms. At the center of the atom lays a proton, which serves as a magnetic and reacts to any magnetic field.
On entering an MRI, the first magnet of the two causes the water molecules of the human body to align. The second magnetic field is then turned on and off; causing each atom to change its alignment and then back to its normal state. The knocking sound you hear during the MRI is caused by passing electricity through gradient coils, which in turn causes the coils to vibrate; whereas, ultrasound you use a transducer to press into the skin of a patient, it sends small pulses of inaudible, high-frequency sound waves into the body, the sound waves then hit an object in the body then it bounces back, thus giving you the images on screen.
The importance of having an MRI is early detection and receiving treatment for disease found. MRI scans illustrate between healthy and diseased tissues. Ultrasound is important as well showing your doctors, organs, vessels, and tissues, causing no need to make an incision. Ultrasound also shows doctors how your baby is and if they are measuring correctly to the gestation period they’re in.
The reasons why a patient may have an MRI is due to them showing detailed images of the heart, liver, and the brain. A patient might have a torn ligament, an injury to a muscle or cartilage. MRI can separate the difference in healthy tissues and also, can see an infection. Ultrasound on the other hand diagnoses gallbladder disease. Used in health care to keep track of a fetus and its growth throughout a woman’s pregnancy. Is able to evaluate blood flow. It’s used to evaluate the liver, spleen, gallbladder and any other stomach issue. Any internal body structure can be viewed.

The benefits of having an MRI are similar to those of having an ultrasound, both are non-invasive and do not use radiation. Early detection means receiving treatment and hopefully a cure. Risks that can occur with having an MRI are rare but can happen on occasion contrast dye that is used to improve visibility of a tissue can cause nausea, headaches and pain or burning at the site of injection. Allergies can also occur from the contrast dye causing hives and or itchy eyes. People who have a phobia of tight places may have a panic attack. Ultrasound has only one risk that comes to mind, that being prolong exposure to ultrasound energy, besides that there are none.
