Discovering an adrenal mass—whether during routine imaging or while investigating symptoms—can naturally cause anxiety. You might wonder, “Is it serious? Will I need surgery? What does this mean for my health?” At the Dr. Rami Hamed Center (DRHC) in Dubai, we understand how these questions can weigh heavily on your mind. Thankfully, advancements in imaging like MRI (Magnetic Resonance Imaging) offer a safe, detailed, and non-invasive way to evaluate adrenal masses and guide the next steps in care, often without surgery.
What Are Adrenal Masses?
The adrenal glands are two small glands that sit above the kidneys and produce important hormones such as cortisol, adrenaline, and aldosterone. An adrenal mass refers to any abnormal growth in or around these glands. Most adrenal masses are benign (non-cancerous), but some may require treatment depending on their size, hormone production, or imaging characteristics.
Common types include:
- Adrenal adenomas (benign, often non-functioning)
- Pheochromocytomas (hormone-producing tumors)
- Adrenal carcinomas (rare cancerous tumors)
- Metastatic lesions (cancer that has spread from another organ)
Why MRI is a Key Tool in Evaluating Adrenal Masses
MRI (Magnetic Resonance Imaging) uses a magnetic field and radio waves to produce highly detailed images of the body’s internal structures. It is especially valuable when examining soft tissues, including the adrenal glands, and offers several advantages:
- No radiation exposure (unlike CT scans)
- Excellent soft tissue contrast, which helps distinguish benign from suspicious lesions
- Functional imaging options, such as chemical shift MRI, to assess fat content in the mass
- Safe for most patients, including those needing repeated scans
What to Expect During an Adrenal MRI
At DRHC Dubai, we prioritize your comfort and peace of mind. Here’s what typically happens:
- Preparation: In most cases, no fasting or special preparation is required. You’ll be asked to remove any metal items (jewelry, watches, etc.).
- The Scan: You’ll lie on a padded table that slides into the MRI machine. The scan is painless, though you’ll hear some loud tapping or thumping noises (earplugs or headphones are provided).
- Duration: An adrenal MRI usually takes 30 to 60 minutes.
- Contrast Use: In some cases, a contrast agent (gadolinium) may be injected through a vein to enhance image quality. This is generally well-tolerated and safe.
When MRI is Especially Recommended
MRI may be preferred over CT in the following situations:
- When radiation exposure is a concern (e.g., in younger patients or during pregnancy)
- When a CT scan yields inconclusive results
- When assessing known pheochromocytomas, which often show clearer features on MRI
- In patients with known cancer elsewhere, to evaluate possible adrenal metastasis
