21. Newer technologies such as 3D fluoroscopy are being developed to aid in placement of these types of drainage tubes. 22. Radiographers now perform fluoroscopy , computed tomography, mammography, ultrasound, nuclear medicine and magnetic resonance imaging as well. 23. This may be done using a portable ultrasound scanner, or with fluoroscopy ( moving X-ray pictures ). 24. It is often used as the input phosphor of an x-ray image intensifier tube found in fluoroscopy equipment. 25. Fluoroscopy , using an x-ray machine with an image intensifier, has applications in many areas of medicine.26. Fluoroscopy -based methods are easier to handle in routine cases with normal anatomy, or cases with lesser deformities.27. Polyiodoorganic compounds are sometimes employed as X-ray contrast agents, in fluoroscopy , a type of medical imaging. 28. The original difference was that radiography fixed still images on film whereas fluoroscopy provided live moving pictures that were not stored. 29. Percutaneous device closure involves the passage of a catheter into the heart through the femoral vein guided by fluoroscopy and echocardiography. 30. The latter are often carried out in the operating theatre, using a portable fluoroscopy machine called a C-arm.
