PRELIM Flashcards
In angiography the BLANK is most often used for arterial access.
common femoral artery
The idea of subtraction images was first proposed by the BLANK when he was able to produce subtracted images using plain films.
Dutch radiologist Ziedses des Plantes in the 1935
The control room should be large, perhaps
100 ft^2.
Large steel container.
* Inside the container are arranged a no. of strong wire separators.
* 30 sheets of film.
LOADING MAGZINE
allows the radiologist to position the catheter within the vascular network.
guidewire
Vessels under investigation in angiography are injected with
radiopaque contrast media.
Can change films –6/s or 1/5s
THE AOT CHANGER:
catheter diameter is categorized in
French (Fr) sizes, with 3 Fr equaling 1 mm in diameter.
The procedure room itself should not be less than
20 ft. along any wall
and not less than 500 ft^2.
The imperfection can be corrected with second-order subtraction, which is developed by
Hanafee and Shinno
The x-ray tube used for IR procedures has a
small target angle, a large- diameter massive anode disc, and cathodes designed for magnification and serial radiography.
introduced coronary angiography
Melvin Judkins
Lid is a sliding section in a side which can be pushed down by firm finger pressure and is retained by central spring loaded catch.
RECEIVING CASSETTE:
In the early 1960s, BLANK pioneered transbrachial selective coronary angiography.
mason jones
has an angled tip joined to a gentle curve and is used for introduction into celiac, renal, and mesenteric arteries.
The C2 or Cobra catheter
“DSA” means
“Digital Subtraction Angiography”
In the early 1960s, BLANK pioneered transbrachial selective coronary angiography.
Mason Jones
matching one image over another so that bony landmarks are precisely superimposed.
Registration
is the radiological study of blood vessel in the
body after the introduction of iodinated contrast media.
angiography
It is simply a technique by which bone structures images are subtracted or canceled out from a film of bones plus opacified vessels, leaving an unobscured image of the vessels.
SUBTRACTION?
is highly curved for approach to sharply angled vessels.
The Simmons catheter
Shallow, polished metal container.
RECEIVING CASSETTE:
In 1953 BLANK described a method of arterial access in which a catheter was used.
Sven Ivar Seldinger
After the procedure has been performed, when the catheter is removed, the femoral puncture site must be
manually compressed.
introduced visceral angiography
Charles Dotter
PHOTOGRPAHIC SUBTRACTION TECHNIQUE
Introduced by Zeides des Plantes
The technique can be applied in all forms of angiography, wherever
the vessels are superimposed in bone structures.
PHOTOGRPAHIC SUBTRACTION TECHNIQUE
ANGIO?
Means blood vessel
radiographic image obtained with the contrast media induced in the patient.
Series film
the procedure became safer as no sharp devices need to remain inside the vascular lumen.
With the introduction of the Seldinger technique in 1953,
The most common complication associated with catheter angiography is
continued bleeding at the puncture site.
Other risk factors are related to kidney failure.
Radiographs in 2 planes simultaneously-one mounted vertically and
other horizontal.
THE AOT CHANGER:
Two of these changers can be coupled electronically and mechanically and will operate out of phase or synchronously with
each other.
THE AOT CHANGER:
Interventional radiology procedures began in the
1930s with angiography.
are fabricated of stainless steel and contain an inner core wire that is tapered at the end to a soft, flexible tip.
Guidewires
reverse tone duplicate of radiographic image, showing black changed to white and white to black.
Reversal film or mask film
developed the technique of contrast x-ray cerebral angiography to diagnose diseases, such as tumors and arteriovenous malformations.
The Portuguese neurologist Egas Moniz, (Nobel Prize winner 1949), in 1927
A technique by which bone structure images are subtracted, or canceled out, from a film of bones and opacified vessels, leaving an
unobscured image of the vessels.
PHOTOGRPAHIC SUBTRACTION TECHNIQUE
Mechanically easier to wind roll films. *12/s.
THE ROLL FILM CHANGER
for guidewires is a variation of the tip configuration that was initially designed for use in atherosclerotic vessels filled with plaque.
J-tip
is the acquisition of digital fluoroscopic images combined with injection of contrast material and real-time subtraction of pre- and post contrast images to perform angiography is referred to as digital subtraction angiography.
DSA
designed by Vincent Hinck is used for the femoral approach to the brachiocephalic vessels.
The H1 or headhunter tip
film showing bone structures only, with no patient motion between it and subsequent contrast studies. For these reasons zero film is exposed just before contrast medium is injected into vessels
Zero film or scout film
have side holes for ejecting contrast media into a compact bolus.
Pigtail catheters
The digital image receptor begins with a television camera pickup tube or a
charge-coupled device (CCD).
