Many patients have health issues that require living with an implanted device, such as a pacemaker that helps the heart keep its rhythm. For safety reasons, when a person with an implanted device needs an MRI, scanning can be limited to an MRI machine with a lower magnetic field, such as a 1.5 Tesla (or 1.5T) MRI scanner. However, when a patient needs a brain scan, an MRI with a stronger magnetic field, a 3T MRI, is the best technology to get high-quality images. 

 

A few years ago, Mayo Clinic received the first compact 3T MRI scanner, an advanced prototype developed under an NIH-funded collaboration between GE Research and Mayo Clinic. The compact 3T scanner is a small, high-performance machine with a narrow central chamber, known as the patient bore. The small bore of the compact 3T scanner allows for scans of the head and extremities. For patients with metal implanted devices, whether pacemakers or spinal stimulators, a major advantage of using the compact 3T MRI for a brain scan is that the strength of the electromagnetic fields drops off rapidly outside the bore and, therefore, is lower at the location of the implanted device than around the brain. This talk explores whether this compact 3T scanner can be used for brain scans of patients with metallic implanted devices.

Lydia Bardwell Speltz, PhD of Mayo Clinic

Biography:

Dr. Lydia Bardwell Speltz is a current postdoctoral fellow in the Mayo Clinic Department of Radiology under the advisement of Drs. Yunhong Shu and Shigao Chen. She graduated in 2017 with dual undergraduate degrees in applied mathematics and mechanical engineering from the University of Northwestern- St. Paul and the University of Minnesota, respectively. She completed her doctorate at the Mayo Clinic Graduate School of Biomedical Sciences in 2023 under the advisement of Dr. Matthew Bernstein in the Compact 3T Laboratory. Her graduate research focused on MRI safety evaluation for subjects with implanted devices, and she received her certification as a Magnetic Resonance Safety Expert in 2022 during her doctoral work.
