A Bone Scan is a sort of a test which will definitely help you to find out the causes of the kind of back pain you have. In the process of scanning you would come to know any sort of damage done to the bones and this can also reveal the presence of cancer in the bone structuring. Scanning is more effective than a normal x-ray as it can make things clearly understandable to you. For conducting a Bone Scan a sort of radioactive substance is being applied to the veins especially in the arm area. This substance is known as tracer and it can travel through the bloodstream and enter the bones for proper detection. This is however a time consuming process and thus you need to have patience for this.
