The degree of spinal cord . Find, When various types of cancer spread to the bones, you may be worried about life expectancy. What is meant by the competitive environment? The abnormal signal is due to replacement of the small amounts of fat cells normally found in red marrow, such that T1 signal will decrease to or below the signal from disc or muscle. A CT scan may also show a polka dot appearance in the bone. Heterogenous refers to a structure having a foreign origin.
