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.
Late Payment Penalty. If you file your return within six months after the due date but do not pay the tax due until after that time, your return will be subject to a late payment penalty. Like the late filing penalty, the late payment penalty is assessed at a rate of 6% per month, with a maximum penalty of 30%.
