The needle size, length and type should be selected based on the site, depth and patient's body habitus. 22–24G needles are sufficed for most injections. [1] As an example, ultrasound-guided hip joint injection [16] can be considered when symptoms persist despite initial treatment options such as activity modification, analgesia and physical ...
Anterior longitudinal approach. An arrow parallel to the long axis of the transducer is drawn on the skin adjacent to the end of transducer where the needle will be introduced. [1] Ultrasound-guided hip joint injection is a joint injection in the hip, assisted by medical ultrasound. Hip and groin pain often presents a diagnostic and therapeutic ...
An interventional radiologist makes a tiny incision in the skin to insert a special needle into the body. Using a live computed tomography (CT) scan or an ultrasound, the doctor guides the needle to the tumor. The interventional radiologist generates electromagnetic microwaves that can destroy the tumor.

Medical ultrasound includes diagnostic techniques (mainly imaging techniques) using ultrasound, as well as therapeutic applications of ultrasound. In diagnosis, it is used to create an image of internal body structures such as tendons, muscles, joints, blood vessels, and internal organs, to measure some characteristics (e.g., distances and velocities) or to generate an informative audible sound.
Under ultrasound guidance, the operator inserts a 16.5 gauge × 11.8″ (1.6 mm × 300 mm outer diameter) needle through the vaginal wall and into an ovarian follicle, taking care not to injure nearby organs and blood vessels. The other end of the needle is attached to a suction device.
Most image-guided surgical procedures are minimally invasive. A field of medicine that pioneered and specializes in minimally invasive image-guided surgery is interventional radiology. A hand-held surgical probe is an essential component of any image-guided surgery system as it provides the surgeon with a map of the designated area. [8]
Ultrasound can ablate tumors or other tissue non-invasively. [4] This is accomplished using a technique known as high intensity focused ultrasound (HIFU), also called focused ultrasound surgery. This procedure uses generally lower frequencies than medical diagnostic ultrasound (250–2000 kHz), but significantly higher time-averaged intensities.
Medical intervention Epidural administration A freshly inserted lumbar epidural catheter. The site has been prepared with tincture of iodine, and the dressing has not yet been applied. Depth markings may be seen along the shaft of the catheter. ICD-9-CM 03.90 MeSH D000767 OPS-301 code 8-910 [edit on Wikidata] Epidural administration (from Ancient Greek ἐπί, "upon" + dura mater) is a method ...
