INTRODUCTION: Coronary and peripheral stents are increasingly being used for creating and maintaining flow in otherwise blocked blood vessels. with stents are routinely imaged at 1.5T and 3T where the safety and MRI compatibility of some of these devices have been previously investigated [1]. With the. availability of ultra high field scanners, there is now necessity to perform MRI safety and compatibility studies at these higher fields. We have investigated the magnetic. interactions (translational attraction and torque), heating, and levels of artifacts for some widely used coronary and peripheral stents at 7T.
1 The penalty for filing late is normally 5 percent of the unpaid taxes for each month or part of a month that a tax return is late. 2  That penalty starts accruing the day after the tax filing due date and will not exceed 25 percent of your unpaid taxes.
