Answer

There are several factors that limit the widespread use of breast MRI, such as the following:

  • High equipment cost.

  • Limited scanner availability.

  • Need for the injection of a contrast agent.

  • No standard technique.

  • Poor throughput compared to that of US or mammography.

  • Large number of images.

  • Relatively long learning curve for interpretation.

  • False-positive enhancement in some benign tissues (limited specificity). [25]

  • Variable enhancement of in situ carcinoma.

  • An incidence of slowly or poorly enhancing invasive carcinomas of about 5%. [26]
