At Delaney Radiology, our radiologists perform several types of minimally invasive, image-guided procedures for specialized diagnostic or treatment purposes. This includes:
- Arthrography—X-ray guided injection of anesthetic and contrast agent into the joint of interest. The purpose is to better image the internal anatomy of the joint for more accurate diagnosis and surgical planning.
- Therapeutic Joint Injection—In a procedure that has both diagnostic and pain management purposes, an interventional radiologist injects an anesthetic and steroid into the joint. The response to the injection determines whether the targeted joint is the cause of the pain, while also providing temporary pain relief that can last from hours to months.
- Facet Injection—In this procedure, which our interventional radiologists perform only in a hospital setting, a precise injection of anesthetic and steroid is administered into the small joints of the neck or back. The purpose is to determine if the facet joint is the cause of pain (as determined by response to injection) and to obtain pain relief lasting hours to months. There are two facet joints at each spinal segment with five lumbar (lower back) segments and seven cervical (neck) segments. Often, multiple injections are performed at different segments to identify which segments are generating pain. The procedure is very important for precise diagnosis and treatment of neck and low back pain.
