How much does knee cortisone shot cost?
It costs about $1500-$2000 if you have it done using a guided injection under flouroscopy, a form of radiation. It can also be done using ultrasound for about the same price. If you have a good sports doc he can do it himself manually in five minutes for under $300.
Grid control X-ray tube versus dual X-ray tube?
A Grid Controlled X-ray Tube is a triode in which a third electrode is introduced between the Anode and Cathode. This electrode is normally neutral so the x-ray production can take place. However, one can decide when to cut the exposure by introducing negative charge on this. This will then stop (repel) the electron from reaching the Anode and x-ray production is stopped. Therefore, the elecrode with a negative charge can as a timer or if chrge is given intermittently, it acts as a device to have flouroscopy in pulses.
Why is contrast medium used in certain diagnostic tests?
Contrast is typically a dye that helps to outline organs or blood vessels. Flouroscopy, MRIs, or CAT scans can see much of the body structures without contrast, but to obtain more detailed images a physician may order the tests to be done "with contrast". Other types of contrast material may be barium (ex. a "barium swallow" or upper GI with contrast shows the esophagus and stomach) or radioactive (ex. for thyroid testing).
