With an aging population, large joint replacements and cardiac implantable devices are becoming increasingly prevalent. Also, the prevalence of conditions needing an MRI examination, such as neurodegenerative diseases, cancer and musculoskeletal diseases, increases with age. Not all implanted devices are an absolute contraindication for MRI anymore. Patients with MR Conditional implants can undergo MRI, but only under clearly defined conditions and performed by well-trained staff. In this article, four experts discuss scanning patients with MR Conditional implants.
At-a-glance:
- Four MRI experts discuss the scanning of patients with MR Conditional implants
- As the population ages, there's a rising prevalence of joint replacements, cardiac devices and MRI-needing conditions like neurodegenerative diseases, cancer and musculoskeletal issues
- Need for MRI scans in patients with orthopedic implants, driven by increased implant prevalence in older adults
- There are currently 34 million MRI patient exams per year within the USA. About 3.9% of the US population are presently carrying an orthopedic or cardiac implant
