Advanced Magnetic Resonance Imaging (MRI) Scans for Clear Answers
At Lahey Clinic, you have access to advanced technology, experienced radiologists and a team focused on safety and comfort. Magnetic Resonance Imaging (MRI) scan results are read quickly and shared with your care team so your next steps can move forward without delay.
What Is an MRI Scan?
MRI is a powerful, non-invasive imaging modality that uses strong magnetic fields and radio waves to generate detailed images of the body’s internal structures. Unlike X-ray or CT, MRI does not use ionizing radiation, making it a preferred choice for many diagnostic applications. It excels in visualizing soft tissues, making it important in evaluating the brain, spinal cord, joints and abdominal organs.
MRI exams are highly versatile and include a wide range of studies such as brain and spine imaging for neurological conditions, musculoskeletal scans for joint and soft tissue injuries, and abdominal and pelvic imaging for organ assessment. Advanced techniques like MR angiography (MRA) allow for detailed vascular imaging, while functional MRI (fMRI) maps brain activity by detecting changes in blood flow. Cardiac MRI is also gaining prominence for its ability to assess heart structure and function with precision.
The field of MRI is evolving rapidly, driven by technological innovation and clinical demand. High-field and ultra-high-field MRI systems now offer unprecedented image resolution, enabling earlier and more accurate diagnoses. Techniques such as diffusion tensor imaging (DTI), spectroscopy and whole-body MRI are expanding the scope of what can be visualized and understood non-invasively.
MRI Technology Designed With You in Mind
MRI technology continues to improve. Depending on your needs, your scan may be performed using:
- High-field MRI systems that produce highly detailed images
- Open or wide-bore MRI systems designed to provide more space
- Specialized MRI units for brain, spine, or joint imaging
Your care team selects the most appropriate system based on your condition and medical history.
More About MRI Scans
Safety of MRI Scans
MRI scans are considered very safe for most people. Because they use magnets, it is important to tell your care team if you have any implanted medical devices, metal fragments or prior surgeries.
Your safety is always reviewed before the scan begins. Imaging staff monitor you throughout the exam.
What to Expect During Your MRI Scan
Most MRI scans take between 30 and 60 minutes. You will lie still on a padded table while images are taken. The machine makes loud tapping or thumping sounds, so ear protection is provided.
In some cases, contrast dye may be given through an IV to improve image quality. If you are concerned about claustrophobia or anxiety, let your care team know in advance. Options may be available to help you feel more comfortable.
Your Scan Results & Records
You will be told when and how to expect your imaging results. Many results will appear in your Patient Portal when available.
