Lawnwood Regional Medical Center & Heart Institute Medical Imaging

1. Outpatients with low back pain who had an MRI without trying recommended treatments first, such as physical therapy

If a number is high, it may mean the facility is doing too many unnecessary MRIs for low back pain.

2. Outpatients who had a follow-up mammogram or ultrasound within 45 days after a screening mammogram

A number that is much lower than 8% may mean there's not enough follow-up. A number much higher than 14% may mean there's too much unnecessary follow-up.

3. Outpatient CT scans of the abdomen that were "combination" (double) scans

The range for this measure is 0 to 1. A number very close to 1 may mean that too many patients are being given a double scan when a single scan is all they need.

4. Outpatient CT scans of the chest that were "combination" (double) scans

The range for this measure is 0 to 1. A number very close to 1 may mean that too many patients are being given a double scan when a single scan is all they need.
