(WTVR) - Doctors have found a new way to diagnose and treat arthritis.
Some are now using ultrasounds to take a look at the joints and pinpoint inflammation with better accuracy.
It can guide them as they inject medication or drain fluid.
The ultrasound is inexpensive and can be done immediately at a patient's bedside eliminating the need for an x-ray or an MRI which exposes the patient to radiation and can be expensive.
Traditionally doctors use their fingers to feel the joint and see if there is inflammation or swelling.
