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.
Penalty for Failure to Timely File Return: If a taxpayer is required to file an income or excise tax return and fails to timely do so, a late filing penalty may be assessed. The penalty is 5% of the amount of unpaid tax per month (or partial month) the return is late, up to a maximum of 25%. A minimum penalty of $135 may apply for returns over 60 days late. The minimum penalty is the lesser of $135 or 100% of the tax due on the return.
