MAGNETIC RESONANCE IN MÁLAGA

Magnetic resonance imaging is an imaging technique that uses magnetic fields and radio waves to create detailed images of the body’s organs and tissues, aiding in the diagnosis of various medical conditions.

Open MRI is a diagnostic imaging technique that uses magnetic fields and radio waves to create detailed images of the body’s organs and tissues. Unlike conventional MRI, the open version features a more spacious and open design, which is more comfortable for patients, especially those who are claustrophobic or overweight.

✔️ Benefits of Open MRI

• Patient Comfort: The open design reduces feelings of confinement and anxiety, offering a more pleasant experience for the patient.
• Improved Access: Ideal for people who are overweight or who need greater positioning flexibility during the exam.
• Image Quality: Provides high-quality images that are crucial for an accurate diagnosis.
• Versatility: Can be used to evaluate various parts of the body, including the brain, spine, joints, and internal organs.

An MRI detects abnormalities in soft tissues, organs, blood vessels, and the central nervous system.

The difference between a CT scan and an MRI is that a CT scan uses X-rays to obtain images primarily of bony structures, while an MRI uses magnetic fields to better visualize soft tissues.

Before the exam, it is recommended to:

Tell your doctor: If you have metal implants, pacemakers, or other medical devices, you should tell your doctor, as they may interfere with the exam.
Fasting: In some cases, you may be asked to avoid eating or drinking for several hours before the procedure.
Comfortable clothing: Wear comfortable clothing and avoid clothing with metal elements. In many cases, you will be provided with a gown to change into.

• Entering the Exam Room: You will lie on a table that slides into the open MRI scanner.
• Stay still: It’s crucial to stay as still as possible to get clear images. You can breathe normally, but avoid sudden movements.
• Length: The exam usually takes 30 to 60 minutes, depending on the body part being evaluated.
• Noise: The equipment may make loud noises during the exam. You will be provided with earplugs or headphones to minimize discomfort.

Once the exam is complete, you can resume your normal activities immediately. The radiologist will analyze the images and send a detailed report to your doctor, who will discuss the results and next steps with you.

Magnetic resonance imaging (MRI) is a medical imaging technique that uses magnetic fields and radio waves to produce detailed images of the body’s organs and tissues.
There are two main types of MRI studies: contrast-enhanced and non-contrast.
Here are the differences between the two:

Non-contrast MRI

A non-contrast MRI is performed without the injection of contrast agents into the body.

• Procedure: The patient lies on the MRI table and is placed in the scanner.
  The scanner uses magnetic fields and radio waves to create detailed images of the inside of the body.
• Indications: Used to obtain detailed images of internal structures without the need for contrast enhancement of tissues.
  Indicated to evaluate the brain, spinal cord, joints, bones, and internal organs without suspicion of very specific or small injuries.
• Advantages: Does not involve the injection of chemicals into the body, which reduces the risk of allergic reactions or side effects.
  It is safer for people with kidney problems or allergies to contrast agents.

Contrast-Enhanced MRI

A contrast-enhanced MRI involves the injection of a contrast agent (usually gadolinium) into the bloodstream before or during the study.

• Procedure: Similar to non-contrast MRI, but includes the injection of contrast.
  The contrast agent enhances the visibility of certain structures and tissues by altering the way they respond to the magnetic field and radio waves.
• Indications: Used when greater detail is needed to evaluate tumors, inflammation, infections, vascular problems, and other pathologies.
  It is useful for observing the blood-brain barrier, tissue perfusion, and vascularity of tumors.
• Advantages: Provides clearer and more detailed images of certain tissues and structures.
  Helps to better detect and characterize lesions, as the contrast highlights abnormal areas that may not be visible on a non-contrast MRI.
• Disadvantages: It may not be suitable for all patients, especially those with severe kidney failure or allergies to gadolinium.
  Some people may experience minor side effects, such as nausea or a warm feeling after the injection.
