  2. Fluoroscopy - Wikipedia

    en.wikipedia.org/wiki/Fluoroscopy

    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 ...

  3. Digital subtraction angiography - Wikipedia

    en.wikipedia.org/wiki/Digital_subtraction...

    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 ...

  4. Pulmonary angiography - Wikipedia

    en.wikipedia.org/wiki/Pulmonary_angiography

    Selective pulmonary angiogram revealing significant thrombus (labelled A) causing a central obstruction in the left main pulmonary artery. Pulmonary angiography (or pulmonary arteriography,conventional pulmonary angiography, selective pulmonary angiography) is a medical fluoroscopic procedure used to visualize the pulmonary arteries and much less frequently, the pulmonary veins.

  5. Medical imaging - Wikipedia

    en.wikipedia.org/wiki/Medical_imaging

    Two forms of radiographic images are in use in medical imaging. Projection radiography and fluoroscopy, with the latter being useful for catheter guidance. These 2D techniques are still in wide use despite the advance of 3D tomography due to the low cost, high resolution, and depending on the application, lower radiation dosages with 2D technique.

  6. Interventional radiology - Wikipedia

    en.wikipedia.org/wiki/Interventional_radiology

    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.

  7. Endoscopic retrograde cholangiopancreatography - Wikipedia

    en.wikipedia.org/wiki/Endoscopic_retrograde_cho...

    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]

  8. Hybrid operating room - Wikipedia

    en.wikipedia.org/wiki/Hybrid_operating_room

    A good fluoroscopic view is essential, whereby an exact perpendicular angle to the aortic root is considered to be optimal for the implantation. Recently, applications have been released which support the surgeon in selecting this optimal fluoroscopy angulation or even drive the C-arm automatically into the perpendicular view to the aortic root.

  9. G-arm medical imaging - Wikipedia

    en.wikipedia.org/wiki/G-arm_medical_imaging

    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.
