Essential Guide for First-Time MRI Scan

TL;DR

MRI (Magnetic Resonance Imaging) is a diagnostic imaging technique that uses a magnetic field and radio waves to create detailed images of body tissues and organs. The procedure involves preparation, including avoiding metal objects and informing staff of any medical conditions like claustrophobia or implants. MRI scans vary in duration (15 minutes to 2 hours) depending on the area being scanned, and results are typically available within 2-3 hours after the scan.

MRIs are preferred over other imaging techniques for their non-invasive nature, lack of radiation, superior soft tissue contrast, and functional imaging capabilities. Contrast MRIs enhance visibility for evaluating damage in soft tissues, while non-contrast MRIs are effective for diagnosing injuries like fractures or hemorrhages. Commonly prescribed MRIs in Noida include brain, spine, cardiac, and pelvic scans, among others.

Izen Imaging offers expert MRI services and encourages patients to contact them for any queries or assistance with the procedure.

We at Izen Imaging and interventions, daily receive tons of inquiries about MRI scans in Noida centre. Here is a list of some of the most frequently asked questions about MRI preparations and procedures. We request you to go through and also encourage you to call us in case of any query if you are recently prescribed an MRI by your doctor.

General Questions About MRI Scan

What is a MRI Scan?

An MRI (Magnetic Resonance Imaging) scan is a diagnostic imaging technique that uses a powerful magnetic field and radio waves to create detailed pictures of the organs and tissues in the body. It’s a versatile tool used to evaluate a range of morphological and functional targets.

What to Expect During an MRI Scan ?

First you may be asked to take the oral contrast by the staff (if you undergo contrast MRI) which will take up to 45 minutes. After that you will be entering the Room with an MRI machine, it may seem intimidating at first but it is completely safe.

A person undergoing the scan is advised to not wear any metal ornamentals to the scan. You need not to worry about that as the staff will ask you to change into a hospital gown and will proceed only upon confirmation from the Radiologist after the due diligence of standard operating procedures.

You must inform the staff if you are claustrophobic or you have any stents implanted so they can help you in any case as it requires you to stay still while the technician runs the test.

How long does an MRI scan take?

MRIs take longer than other diagnostic imaging techniques, like x-rays, because they require many images to create a 3D picture of the body part. The duration of an MRI scan can vary from 15 minutes to 1 hour.

How much time does it take to get results after the MRI scan ?

In most cases, you won’t get results right away. A radiologist will review your scans and share their findings with your doctor, who will then discuss the next steps with you. But you can expect a report in 2 – 3 hours.

Type of MRITypical Duration
Brain and spine MRITypically 45 minutes
Body MRIUsually 45–60 minutes
Cardiac MRICan take 1.5–2 hours
Knee, ankle, hip, elbow, wrist MRIUsually 25–45 minutes
Breast MRITypically 45 minutes to 1 hour
Shoulder MRIUsually 15–45 minutes
Abdomen MRUsually 45 minutes
Arm MRIUsually 45–60 minutes
Cervical spine MRUsually 30 minute

However, recent research also hints at the development of faster protocols. 3D methods with isotropic resolution can cut the exam time to as little as 5 minutes for musculoskeletal imaging.A single-shot T2-weighted fast spin echo sequence for neurological assessment can take 3 minutes.A biparametric prostate MRI can be done in about 12 minutes.A focused liver screening protocol for hepatocellular carcinoma can be done in about 5 minutes.Pulmonary MRA can be performed in about 5-10 minutes

The timings we have listed are general and not standard. It will be helpful to ask your radiologist beforehand to prepare yourself for the procedure better.

What are the Advantages of MRI over Other Techniques?

MRI is a pillar diagnostic imaging technique of Modern medical practice. It has many advantages over other techniques.

  1. Non-Invasive and Radiation-Free: Unlike X-rays and CT scans, MRI does not use ionizing radiation, making it safer for repeated use and ideal for vulnerable populations, such as pregnant women and children.

  2. Superior Soft Tissue Contrast: MRI offers exceptional detail in imaging soft tissues, making it particularly effective for brain, spinal cord, joint, and muscle evaluations. This level of contrast is unmatched by other imaging methods.

  3. Versatility Across Conditions: It can be tailored to diagnose a wide range of conditions—from neurological and cardiac diseases to musculoskeletal injuries and organ-specific pathologies.

  4. Dynamic and Functional Imaging: MRI can capture real-time functional data, such as blood flow (via MR Angiography), organ movement (e.g., Defecography MRI), or brain activity (functional MRI), providing insights beyond static images.

  5. Contrast Agent Precision: The contrast agents used in MRI are less likely to cause allergic reactions compared to those used in CT scans, and specialized agents can target specific tissues or conditions, enhancing diagnostic accuracy.

What is the difference between a MRI scan with contrast and one without contrast?

The main difference between the two is that MRI with contrast utilizes an agent which enhances the visibility of the affected area. MRI contrast agents can be introduced into the body either orally or via intravenous injection.

Several specialized contrast agents have been designed to highlight liver abnormalities distinctly. Additionally, certain agents have the capability to focus on other organs, detect inflammatory processes, or identify specific tumors. The patient is advised to expect an hour of pre-scan process in case you are required to take the contrast orally.

Contrast MRIs are preferred when extent of damage is being evaluated in case soft tissues are involved.It can better identify lesions in the acute phase, such as edema, infarction, or contusion without hemorrhage, which may later be associated with severe complications. Non-contrast MRIs can identify spinal cord injuries such as hemorrhage and other bone fractures.
