MRI Pelvis Without Contrast

What is MRI Pelvis Without Contrast? MRI (Magnetic Resonance Imaging) uses powerful magnets and radio waves to create detailed pictures of soft tissues, bones, and organs inside the pelvis. “Without contrast” means no gadolinium-based dye is injected, making the procedure quicker and safer for people with kidney issues or contrast allergies.

• Pelvic Organs: Uterus (size, position, junctional zone), ovaries (follicle count, masses), prostate (volume, zonal anatomy), bladder (wall thickness, diverticula).
• Bony Structures: Hip joints (cartilage, effusion), sacrum, coccyx, pelvic inlet width.
• Soft Tissues: Ligaments (round, broad, uterosacral), pelvic-floor muscles, lymph nodes (short-axis diameter >8 mm is flagged).

• Unexplained pelvic pain – rule out endometriosis, adenomyosis, or musculoskeletal strain.
• Fertility assessment – evaluate uterine anomalies, tubal patency by MRI, or low seminal vesicle volume.
• Tumour or cyst detection – characterise ovarian cysts, solid masses, or prostate nodules.
• Post-surgical follow-up – check for residual tumour, scar tissue, or post-operative collections.

• No gadolinium exposure – eliminates rare but serious nephrogenic systemic fibrosis risk.
• Safe for kidney-compromised patients – no need for creatinine blood test beforehand.
• Detailed soft-tissue definition – excellent contrast for uterine layers, endometrium, and bowel wall.
• Shorter scan time vs contrast exams – saves 10–20 minutes on the table.

Instructions

• Fasting not required – eat and drink normally.
• Remove metal objects – jewellery, belts, piercings, credit cards.
• Inform staff about implants – pacemaker, aneurysm clips, IUD strings (copper or hormonal).

Prerequisites

• Fill a short safety questionnaire.
• Change into metal-free hospital gown.
• Lockers provided for valuables.

Best Time to Take the MRI Pelvis Without Contrast

• Any day is acceptable.
• For women, mentioning your menstrual phase helps correlate endometrial thickness.

Eligibility

• Pregnancy: Generally safe in second/third trimester if clinically urgent; first-trimester scans postponed unless essential.
• Claustrophobia: Mild sedation available after doctor’s approval.

Procedure for Taking an MRI Pelvis Without Contrast

1. Lie supine on the MRI table.
2. Pelvic coil placed over lower abdomen for signal boost.
3. Earplugs + headphones to reduce noise.
4. Hold still while table slides into magnet; breathe normally.
5. Total time: 30–45 minutes.

Caution Before Taking the Test

Tell the technologist if you have:

• Cardiac pacemaker
• Cochlear implant
• Orthopaedic screws or plates that may heat up
• Metallic eye injury history

• Minimal risk: No radiation or dye-related side effects.
• Limitations: Very small lesions (<5 mm) may be harder to see. Motion artefacts can blur images if you move.
• Contraindications: Pacemakers, certain cochlear implants, or metallic fragments inside the eye may prevent scanning.
