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.
The penalty is 5 percent of the unpaid tax as of the due date plus 1/2 of 1 percent each month, or part of a month the tax remains unpaid, not to exceed 40 months. The maximum penalty is 25 percent of the total unpaid tax. A delinquent penalty will be charged on unpaid taxes if a return is filed late. The penalty is 5 percent of the unpaid tax due for every month that the return is late, up to a maximum penalty of 25 percent of the unpaid tax. The minimum penalty for filing a tax return more than 60 days late is $135 or 100 percent of the unpaid tax, whichever is less.
