Humans affect Earth's climate through many mechanisms by changing the abundance of greenhouse gases and air pollutants, and by altering the reflectivity of Earth's surface through changes in land use.
Siemens estimate the cost of operating MRI machine with a 1.5T to be around $ 300,000 a year (Keefer, 2011). This includes cost of acquiring and a technologist to operate the machine, cost of power and maintenance cost. The salary for an MRI radiologist ranges between $ 50,000 and 60,000 a year (Keefer, 2011).
MRI cost can range between $400 to $3,500 depending upon which MRI procuedure is performed (example: brain mri vs. shoulder mri) and where you have the MRI test performed.The same exact MRI test can vary by hundreds of dollars from testing facility to testing facility.RI's are expensive because of the price of the equipment. With the average MRI machine costing over $1 million dollars they have to charge enough per test to cover the expense of the machine. Now, that doesn't mean you can get a better price that what is published.
