MRI users may be interested in the latest advice from MRISafety.com regarding scanning patients with coronary stents:
It states that patients requiring MRI scans that have implanted Coronary Stents can be scanned
- Immediately after placement of the stents
- With two or more overlapping stents
- Where make or model of stent(s) are unknown
There are a few conditions, listed below, that must be met in order to do this, but all centres will meet these with commercially available scanners:
- Patients with all commercially available coronary artery stents (including both drug-eluting and non-drug eluting or bare metal versions) can be scanned at 1.5-Tesla/64-MHz or 3-T/128-MHz.
- Patients with all commercially available coronary artery stents can undergo MRI immediately after placement.
- The MRI examination must be performed using the following parameters:
- 1.5-Tesla or 3-Tesla, only
- Whole body averaged specific absorption rate (SAR) of 2-W/kg, operating in the Normal Operating Mode of operation for the MR system
- Maximum time, 15 min. per pulse sequence (multiple sequences per patient are allowed
