  1. Introduction to Angiographic Procedures and Equipment RAD TECH 255 SP 2007

  2. Carltons – CH 42

  3. ANGIOGRAPHY • RADIOGRAPHIC EXAM OF THE ARTERIES USING CONTRAST MEDIA

  4. Special Procudures –Sterile Environment (like OR)

  5. Some history…. • The first angiogram was performed only months after Roentgen's discovery, • when two physicians injected chalk into an amputated hand • and created an image of the arteries

  6. Technical innovations • image intensification • three-phase generators • rapid film changers • automatic pressure injectors • advanced catheter technology • all helped to establish angiography as an essential diagnostic tool by the 1960s

  7. Other Technologieswhich demonstrate the vasculature to a greater or less degree • CT • MRI • ultrasound (particularly Doppler) • nuclear medicine • are all used to image vessels and each has its advantages and disadvantages

  8. Vessel imaging is a constantly evolving area. • Current developments • such as CT • magnetic resonance angiography (MRA) • may change this in the future.

  9. AngiographyDigital subtraction angiography (DSA) • is still considered the gold standard of vessel imaging when other modalities are inconclusive

  10. development of interventional techniques An important offshoot of angiographic imaging • have created a therapeutic technology • Embolization • intra-arterial drug therapy • transluminal angioplasty • are among the procedures that have radically changed and broadened the scope of the diagnostic imaging department

  11. Angiographic Equipment • Vascular studies usually require a room or suite of rooms specifically designed to accommodate the sophisticated and accessory equipment needed to perform angiography and interventional procedures

  12. EQUIPMENT • Biplane C-arm digital imaging  • Autoinjector • --syringes, a heating device, • a high-pressure mechanism • a control panel    Rapid film changer (NOW DIGITAL) • Cut film 6 &Cassette changer /magazine • Image Intensifying screen  • Sliding table

  13. COST • Angiography equipment and MRI scanners • are major investments • usually costing between • $750,000 and $1 million DOLLARS

  14. The procedure room should be large enough to accommodate all of the equipment as well as radiologic and ancillary staff • Special procedures sometimes require a general anesthetic that necessitates extra equipment and staff. • These procedures are also more hazardous to the patient and each room must be equipped to deal with emergencies that may occur

  15. Remote computerized equipment should also be housed adjacent to the special room. • Although there must be adequate protection for all operators and staff, there must at all times be clear access and view of the patient being examined
