Different Types of MRI Scanners Found In MRI Centers In Miami
The MRI (magnetic resonance imaging) procedure is performed in order to get detailed pictures of a person’s internal organs. A doctor may ask you to visit one of the MRI centers in Miami in order to correctly diagnose a disease or to determine the extent of a disease. The MRI machines use powerful magnets and radio-waves to capture detailed images of the internal organs. An MRI machine is linked to a computer where the images are stored. MRI machines do not use ionizing radiation of x-rays unlike an X-ray machine or CT scanner. These machines are equipped with two powerful magnets. They are most important parts of an MRI machine.
The human body is largely (up to 60% in adults) made of water molecules. The brain, heart, lungs, kidneys, skin, muscles, GI tract and bones all contain water molecules. A proton is present at the center of each hydrogen and oxygen atom of water molecules. It is sensitive to the magnetic field and MRI scanners can capture images of the internal organs due to this reason. The patients are inserted into an MRI machine after being sedated at MRI centers in Miami. The water molecules are not methodically arranged inside a human body. However, they become aligned in one direction (north/south) after coming in contact with an MRI scanner. The first magnetic field of the machine performs this task.
The second magnetic field is turned on and turned off successively in a series of high-speed pulses. The hydrogen atoms change their alignment once the magnetic field has been turned on and they revert to the original state when the field is turned off. An MRI scanner can detect these changes and create cross-sectional images of different organs for the doctor. The MRI scanners are fitted with gradient coils. These coils vibrate and create magnetic field when electricity passes through them. You will find different types of MRI scanners in MRI centers in Miami and some imaging centers have more than one type of MRI scanner.
The basic design remains the same in all types of MRI scanners; however, the external structure and features are different. For example, some MRI centers in Miami have a closed-MRI scanner whilst other centers have open MRI scanner. A closed MRI machine is fitted with a container that is cylindrical in shape and that spans a bore diameter of 60 cm.
The closed MRI machine is not suitable for the claustrophobic or obese individual. Some MRI centers in Miami have open MRI scanner due to this reason. The sides stay open in this type of MRI scanner which may even have wider opening. The open MRI machines seem more comfortable than the closed MRI machines, however, generate less detailed images. Some MRI centers in Miami have ‘extremity MRI’ in order to examine the tissues of arms and legs. To read more Click Here
