What are the two major disadvantages of MRI scans?

• release of radiation and poor quality images.
• high cost and the need for shielding from the magnetic signals.
• can only view metabolically active tissues and inadequate availability of equipment.
• release of radiation and the need for a patient to be confined to metal tube for up to 30 minutes.

What is the safest gadolinium?

Over the last three decades, gadolinium contrast injections have successfully been used in hundreds of millions of patients.
