What are the differences between MRI and FMRI?

Magnetic resonance imaging (MRI) provides images of structures inside the body, while functional magnetic resonance (FMRI) evaluates metabolic processes. Both techniques can provide a valuable insight into what is happening inside the patient's body for medical testing, monitoring and research. MRI can be used anywhere in the body, while FMRI studies focus on the brain where the display is particularly important that can reveal very fine changes in the level of activity. In some cases, patients can receive MRI and FMRI scanning. The device can be used to generate high -resolution images where different organs will be clearly different from each other and abnormalities such as tumors can easily be found. FMRI looks specifically on the flow of blood in the brain and is able to detect very small changes. This allows the test to identify when different areas of the darkness become active, which can help a doctor or researcher what the patient's brain does. MRI and FMRI are usually ordered for very different reasons.

One of the key differences between MRI and FMRI is that MRI can generate static images that can later be reviewed for information about the interior of the patient's body. In the FMRI study, the result is a brain activity in real time. It can be frozen on individual frames, such as the peak of brain activity, or can be displayed later in a video form. Scientists might want to use FMRI to identify areas of the brain involved in specific responses, for example, while a doctor may order a test to find out why the patient cannot perform some cognitive tasks.

Before MRI or FMRI, the patient should be checked to ensure that the procedure is safe. Patients cannot wear metal and need to alert the technique of any medical or electrical implants into their bodies. They will also have to lie in a potentially limited environment if the device does not have an open MRI machine that may require sedation to pacietShe kept calm. The device used in MRI and FMRI studies is loud and some patients wear ears that may include music headphones to help them relax.

patients can spend different amounts of time in the device, depending on the purpose of MRI and FMRI. They should get an estimate before the procedure to help them plan. Some studies also require the use of contrasting materials to increase the visibility of certain structures, in which case the patient receives an injection shortly before displaying. Some contrasting agents may cause allergic reactions and patients should make sure that the technician is aware of any history of allergy.
