What is MRI without contrast?

Magnetic resonance imaging (MRI) is a medical diagnostic technique that uses strong magnetic fields to obtain an image of the interior of the patient's body. MRI without contrast, which is usually referred to as a standard MRI scan, does not require any medication or contrasting agent to injection into the body. MRI with increased contrast involves injection of the contrast agent to increase image sensitivity. MRI without contrast is suitable for most conditions unless additional details are required.

MRI The machine uses the magnetic properties of particles in the body to create an image. MRI scans are among the most detailed forms of diagnostic display available to doctors. The advantage of MRI scans is that they do not require the use of ionizing radiation, which could be potentially damaging to the patient, although the machines are expensive to build and maintain.

Standard MRI scanning is known as MRI without contrast. This means that the MRI machine takes a picture of the desired need without the need to be injected into the bodyOntrastial substance. In most situations, MRI is without contrast everything that is necessary to see problems in the body, unless the affected area is very small or difficult to see.

MRI without contrast can be used in most parts of the body. The most common places that require scanning MRI are brain and spinal cord. The joints are also often scanned to detect injury, such as damaged cartilage and torn ligaments.

Before MRI without contrast, patients are usually said to arrive about half an hour earlier. This is that the radiologist can discuss potential MRI scanning problems, such as that the patient has metal implants. Once the MRI machine is used, the patient must avoid movement when scanning occurs. MRI takes a large number of pictures and must be clear and therefore remains important.

In some situations, the doctor may have to see in more detail the specific area of ​​the body using MRI scanning fromwith a height contrast. This requires a contrasting "dye" to the body, either by a single injection or an intravenous drop during scanning. The purpose of the contrast agent is to identify any active problems in the body and increase the sensitivity of the image.
