An arthrogram is a series of images of a joint after injection of a contrast medium, usually done by fluoroscopy or MRI. The injection is normally done under a local anesthetic such as Novocain or lidocaine .
G-arm medical imaging systems are based on fluoroscopic X-ray and are used for a variety of diagnostic imaging and minimally invasive surgical procedures.The name is derived from the G-shaped arm used to connect two X-ray generators and two X-ray detectors, image intensifiers or digital flat panel detectors, to one another.
Hydrodilatation or hydraulic arthrographic capsular distension or distension arthrography is a medical treatment for adhesive capsulitis of the shoulder. [1] The treatment is applied by a radiologist assisted by a radiographer. Contrast medium, a local anaesthetic and cortisone are injected into the joint.
Fluoroscopy was discontinued in shoe-fitting because the radiation exposure risk outweighed the trivial benefit. Only important applications such as health care , bodily safety, food safety , nondestructive testing , and scientific research meet the risk-benefit threshold for use.
Projectional radiography, also known as conventional radiography, [1] is a form of radiography and medical imaging that produces two-dimensional images by X-ray radiation.The image acquisition is generally performed by radiographers, and the images are often examined by radiologists.
Iodinated contrast contains iodine.It is the main type of radiocontrast used for intravenous administration.Iodine has a particular advantage as a contrast agent for radiography because its innermost electron ("k-shell") binding energy is 33.2 keV, similar to the average energy of x-rays used in diagnostic radiography.
Digital subtraction angiography (DSA) is a fluoroscopy technique used in interventional radiology to clearly visualize blood vessels in a bony or dense soft tissue environment. Images are produced using contrast medium by subtracting a "pre-contrast image" or mask from subsequent images, once the contrast medium has been introduced into a ...
Correct diagnosis primarily relies on the reader's experience. Awareness of normal anatomic features is crucial for the interpreter to be able to detect subtle signs of fracture. Fat pads should be carefully examined for convexity, which implies joint effusion (e.g., in the hip and elbow). However, the radiographic technique (positioning in ...
