Testicular MRI Scan: Complete Guide

A testicular MRI scan is a specialised imaging study used to evaluate the testicles, epididymis, and surrounding scrotal structures in detail. While ultrasound is the initial imaging method for scrotal complaints, MRI is increasingly used as a problem-solving tool when ultrasound findings are indeterminate or when more detailed tissue characterisation is needed. This guide explains what a testicular MRI involves and when it might be appropriate.

What a Testicular MRI Scan Shows

Testicular MRI provides superior soft-tissue contrast compared to ultrasound. It can detect and characterise:

• Testicular tumours — distinguishing between different tumour types (seminoma, non-seminoma) and identifying small lesions that may be equivocal on ultrasound
• Benign testicular lesions — epidermoid cysts, Leydig cell tumours, and other non-cancerous masses
• Undescended testes (cryptorchidism) — locating testes not found in the scrotum, particularly in the inguinal canal or abdomen
• Testicular torsion complications — assessing viability of the testis after torsion
• Epididymal abnormalities — cysts, inflammation, or masses
• Scrotal wall and tunica abnormalities — thickening, masses, or calcification
• Post-treatment monitoring — assessing the remaining testis or surgical site after orchidectomy
• Staging — evaluating local extent of known testicular cancer

When You Might Need a Testicular MRI Scan

A testicular MRI may be recommended if you have:

• An indeterminate lesion on scrotal ultrasound that needs further characterisation
• A palpable testicular lump where ultrasound is inconclusive
• Suspected undescended testis not found on ultrasound
• Testicular pain with unclear cause on initial imaging
• A complex scrotal mass requiring detailed tissue analysis before surgery
• Monitoring after treatment for testicular cancer
• Bilateral testicular microlithiasis with suspicious features

If you've found a testicular lump, always see your GP first — they will typically arrange an urgent ultrasound. MRI may follow if the ultrasound findings need clarification.

How to Prepare for a Testicular MRI

• No fasting required: Eat and drink normally
• Clothing: Wear comfortable, loose-fitting clothes. You'll be given a gown
• Metal objects: Remove all jewellery, belt buckles, and piercings
• Support: A towel or support may be used to position the scrotum during the scan
• Contrast: Gadolinium contrast is usually administered for testicular MRI to help characterise lesions
• Medical history: Inform the team about any implants, allergies, or kidney problems

What to Expect During the Scan

A testicular MRI typically takes 30–40 minutes:

1. Positioning: You'll lie on your back on the MRI table. A surface coil is placed over the scrotum to improve image quality
2. Privacy: The scanning team will ensure you're comfortable and positioned appropriately. A towel or scrotal support is used
3. Cannula: A small cannula is placed in your arm for gadolinium contrast injection
4. Scanning: Multiple sequences are acquired. You'll hear the standard MRI knocking sounds — ear protection is provided
5. Contrast injection: Gadolinium is injected partway through, with further images taken to assess how lesions enhance
6. Completion: The cannula is removed and you can leave immediately

The scan is painless, and the team will maintain your privacy and dignity throughout.

Testicular MRI Scan Cost in the UK

Private testicular MRI scans in the UK typically cost between £400 and £800. Scrotal ultrasound is cheaper (£150–£300) and remains the first-line investigation, with MRI reserved for complex cases.

Lola Health offers testicular MRI scans through 150+ UK scanning centres. Results are reported by a specialist radiologist within 7–10 working days. View our testicular MRI scan for pricing and booking.

Testicular MRI and Blood Testing

Blood tests play a critical role in evaluating testicular lumps and suspected testicular cancer. Key tumour markers include:

• AFP (alpha-fetoprotein) — elevated in non-seminomatous germ cell tumours (yolk sac tumours, embryonal carcinoma)
• Beta-hCG (human chorionic gonadotropin) — may be elevated in both seminoma and non-seminoma. Very high levels suggest choriocarcinoma
• LDH (lactate dehydrogenase) — a non-specific marker that correlates with tumour bulk and prognosis
• Testosterone — may be affected in bilateral disease or after orchidectomy
• FSH and LH — can be disrupted by testicular tumours or treatment
• Oestradiol — occasionally elevated in Leydig or Sertoli cell tumours

Start with a Lola Health blood test to check your AFP, beta-hCG, LDH, and testosterone. If results suggest further investigation, a testicular MRI can provide the structural detail your blood results can't show. Peak Insights 70 covers these markers across 70 biomarkers.

If tumour markers are elevated alongside a testicular lump, MRI can help characterise the lesion and guide surgical planning. Even with normal markers, MRI adds valuable information when ultrasound is inconclusive.

Frequently Asked Questions

Is a testicular MRI embarrassing?

The scanning team performs these examinations routinely and will ensure your comfort and privacy. You'll be covered with a gown, and the room is private.

Is testicular MRI better than ultrasound?

Ultrasound is the first-line imaging for scrotal complaints and is excellent for most diagnoses. MRI is used as a second-line investigation when ultrasound is inconclusive or when better tissue characterisation is needed.

Can testicular MRI detect cancer?

Yes. MRI can help characterise testicular masses and distinguish benign from malignant lesions with high accuracy, particularly when combined with tumour markers.

How long does the scan take?

Typically 30–40 minutes.

Is the scan painful?

No. The scan is painless. You'll feel a slight scratch from the cannula insertion for contrast.

Do I need a referral?

For a private testicular MRI through Lola Health, a referral isn't mandatory, though clinical context and prior ultrasound findings help guide the radiologist's assessment.
