Ultrasound Guided Injections
Injections can be done under image-guidance (ultrasound, CT or x-ray). These are more accurate and reduce the risk of injecting the wrong structures when compared with non-guided ('blind') injections.
However, they are more time-consuming, expensive and sometimes less convenient for patients. Therefore, your clinician may perform a non-guided injection first.
Please discuss this with your clinician if you have any concerns.
