Projections Flashcards
most common approach for cerebral angiographic studies
transfemoral approach
other techniques or cerebral angiographic studies
brachial or axillary artery approach
Aortic Arch Angiogram VISUALIZE:
atherosclerotic or occlusive disease of extracranial carotid, vertebral and subclavian arteries
catheter used for Aortic Arch Angiogram
multiple side hole catheter
multiple side hole catheter position
ascending thoracic aorta
[pt pos’n] SIMULTANEOUS BIPLANE OBLIQUE
PROJECTIONS
35° RPO pos’n on the tabletop- MSP -perp to IR
Chin of pt raised
Move shoulders inferiorly
[SIMULTANEOUS BIPLANE OBLIQUE
PROJECTIONS] 35° RPO pos’n PURPOSE:
pt pos’n opens the aortic arch & origins of the great vessels for the AP OB Proj frees the carotid and vertebral arteries from superimposition
[SIMULTANEOUS BIPLANE OBLIQUE
PROJECTIONS] Chin of pt raised PURPOSE:
superimpose the inferior margin of the mandible onto the occiput so much neck is exposed in the frontal rad’ph.
[SIMULTANEOUS BIPLANE OBLIQUE
PROJECTIONS] reference point
level ¼ inch (3 cm) superior to the sternal angle
[SIMULTANEOUS BIPLANE OBLIQUE
PROJECTIONS] CRD
Enter the pt at a level ¼ inch (3 cm) superior to the sternal angle – MP-IR
both AP and LAT PROJ
[SIMULTANEOUS BIPLANE OBLIQUE
PROJECTIONS] Obj
RPO Pos’ns: opened aortic arch, carotid and vertebral arteries free from superimposition
