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).
In some cases, an MRI can produce clearer images than an X-ray or CT scan. Most MRIs are typically covered by health insurance when deemed medically necessary. If deductibles are met, typical out-of-pocket cost consists of copays of $20-$100 for the doctor visit and for the procedure. An open MRI typically costs about the same as a conventional MRI, about $1,000-$5,000, depending on the parts of the body being examined. 2  An upright MRI allows patients to be scanned while standing or sitting, which can be helpful in diagnosing certain conditions.
