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.
So, if you owe the IRS $1,000 and you're 90 days late, first calculate your daily interest charge, which would be about $0.082. Then, multiply it by 90 days to arrive at the total interest charge of $7.40. Two kinds of penalties Late penalties can be a bit tougher to calculate, and depend on whether or not you've filed your return. If you owe the IRS a balance, the penalty is calculated as 0.5% of the amount you owe for each month (or partial month) you're late, up to a maximum of 25%. And, this late penalty increases to 1% per month if your taxes remain unpaid 10 days after the IRS issues a notice to levy property.
