Outpatients with brain CT scans who had a sinus CT scan at the same time
This measures the percentage of patients receiving CT scans (also called CAT scans) of the brain who also received CT scans of the sinuses. CT scans use X-rays to create a high-resolution image of the inside of the body. Brain and sinus CT scans are used to diagnose problems such as severe headaches or chronic sinus infections. Often, only a brain CT scan is necessary because it also shows a large part of the sinuses. However, sometimes both are needed, such as in the cases of head injuries, tumors and serious infections. Because CT scans use X-rays, it is better to perform only a brain CT scan instead of brain and sinus CT scans when possible.
January 2011 - December 2011 data
For the above graph: Lower ↓ performance is better.
Why is there only one graph?
Because this is a new measure, only a limited amount of data is available. As past data on this measure becomes available, we will add another graph showing our performance over time.
