Many implanted devices are labeled MR Conditional, meaning specific, labeled conditions must be met to ensure safe scanning. We developed a software tool for use with a high-performance, compact 3T (C3T) scanner that verifies relevant MR conditions can be met at the location of the device (e.g., abdomen), even if those conditions are exceeded at the level of the anatomy being scanned (e.g., brain). MR parameters assessed include main magnetic field strength, gradient slew rate, RF amplitude (B1+2), and dB/dz. The limited extent of the fields with C3T suggests high-performance exams can sometimes be obtained without compromising patient safety.

After one year, current ISMRM & ISMRT members get free access to both the abstracts and videos. Non-members and non-registrants must purchase access via the ISMRM E-Library.
After two years, the meeting proceedings (abstracts) are opened to the public and require no login information. Videos remain behind password for access by members, registrants and E-Library customers.
