Because fluoroscopy involves the use of X-rays, a form of ionizing radiation, fluoroscopic procedures pose a potential for increasing the patient's risk of radiation-induced cancer. In addition to the cancer risk and other stochastic radiation effects, deterministic radiation effects have also been observed ranging from mild erythema ...
It is used primarily in the evaluation of menisci, cruciate ligaments, articular cartilage, and loose body within a joint. Fluoroscopic allows general view of the medial, lateral, and patellofemoral ligaments of the joint, overall cartilage thickness, focal defects, imbibition (absorption} of contrast material into the articular cartilage (a sign of cartilage fibrillation - splaying and ...
The contrast medium that is used usually produces a sensation of warmth lasting only a few seconds, but may be felt in a greater degree in the area of injection. If the patient is allergic to the contrast medium, much more serious side effects are inevitable; however, with new contrast agents the risk of a severe reaction is less than one in ...
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 ...
The region can be directly visualized with the endoscopic camera while various procedures are performed. A plastic catheter or cannula is inserted through the ampulla, and radiocontrast is injected into the bile ducts and/or pancreatic duct. Fluoroscopy is used to look for blockages, or other lesions such as stones. [8] [9]
Interventional radiology (IR) is a medical specialty that performs various minimally-invasive procedures using medical imaging guidance, such as x-ray fluoroscopy, computed tomography, magnetic resonance imaging, or ultrasound.
A retrograde pyelogram is a medical imaging procedure in which a radiocontrast agent is injected into the ureter in order to visualize the ureter, bladder, and kidneys with fluoroscopy or radiography, using plain X-rays. [13]
The physician controls both the contrast injection, fluoroscopy and cine application timing so as to minimize the total amount of radiocontrast injected and times the X-ray to the injection so as to minimize the total amount of X-ray used. Doses of radiocontrast agents and X-ray exposure times are routinely recorded in an effort to maximize safety.
