MRI

Magnetic resonance imaging — detailed imaging of soft tissues using magnetic fields, no radiation exposure.

MRI (magnetic resonance imaging) uses strong magnetic fields and radio waves to produce detailed cross-sectional images, particularly of soft tissue. Field strength matters: 1.5T is standard, 3T gives better resolution, 7T is research-grade. Most scans take 30-60 minutes. Contrast agents (gadolinium) occasionally used. Contraindicated with some pacemakers, metal implants.

  2. Doctor credentials. Qualifications and specialty come from the doctor's hospital profile and national medical council registers.
  3. Prices. Price ranges come from written hospital quotes and packages, not advertised rates.

  5. Independence. Hospitals cannot pay to change their position on our pages.
