Beautyrest Pressure Smart The standard way to evaluate the nature and class of brain tumors is an MRI scan (note that some hospitals do not have an MRI scanner). MRI has a higher sensitivity for detecting tumors and assessing tumor characteristics than CT scans. Specifically, the relationship of the tumor with the surrounding brain tissue, brain layers, cerebrospinal fluid space, and the structure of the blood vessels in the head appear with a temporary diagnosis of the nature of the tumor. At present, however, many institutions that have MRI scanners still use CT scans as a screening test for tumors, even though MRI scanners are more accurate in recognizing brain tumors. http://www.hirezmediahawaii.com/
