Is aortography safe in patients with aortic dissection? It generally:
Is safe if contrast is not injected into the false channel.

During the injection
Contrast injections may be painful. Check the techniques used in brachiocephalic arteriography that effectively reduce pain?
Use reduce strength contrast
Use non-ionic contrast

Renal arteriogram
What is the best angiographic x-ray view to show the aortic arch?
60 degree LAO
A patient with a resting a/b ratio of 0.4 has a blood pressure of 200/75mmHg. This means that the systolic BP in the
Lower leg is only 80mmHg
Which angiographic position best delineates the origins of the celiac axis and the superior mesenteric arteries?
Lateral
Check the x-ray recording chains that use an image intensifier?
35 mm cine film
4x4” spot film
Digital video disk or tape
Kidney function test

How long will it take to make a contrast injection if the radiologist asks you to perform the pressure injector to “12 for 90”?
7.5 seconds
To reduce the leg circulation time when doing large film from moral arteriography, blood pressure cuffs may be inflated to occlude both femoral arteries for 3 to 10 minutes. Then they are suddenly released, and the contrast is injected. The increased blood flow and reduced circulation time is due to
Extremity hyperemic vasodilation response
Shows no motion but has the widest field and highest resolution
14 x 14” large cut film
Shows no motion but high-resolution
4 x 4 inch spot film
Motion picture film
35mm cine film
Motion and post acquisition video enhancement
Digital video disc or tape
In the “subclavian steal syndrome” the stenosed artery may receive collateral blood flow by stealing blood flow from the
Vertebral artery
Aortography in the shallow RAO projection usually shows the ascending and descending aorta
Superimposed
Iliac and femoral angiograms which show the entire leg circulation on long board type films is termed “femoral
Run-off films”
Check what types of vascular procedures should be pretreated with prophylactic antibiotics
Biliary obstructive jaundice
Urinary obstruction
Tumor devascularization
The current gold standard now used to diagnose deep vein thrombosis is
B-mode ultrasound (compressing veins while imaging them)
Which class of aortic dissection originates in the descending aorta?
Type B of Daily
A patient has claudication symptoms in only his left leg. To perform a unilateral left femoral arteriogram the radiologist wants to enter from the right femoral artery, and pass the catheter across the iliac bifurcation, down the left iliac artery. This is turned a
Contralateral
Computerized digital x-ray imaging
DSA
Thrombosis of leg veins
DVT
Procedure where contrast injected IV to outline renal system
IVP
Artery to front of foot
DP
Artery of intestine
SMA
Radioisotope scan of lung
V/Q
Vascular angioplasty
PTA
X-ray of abdomen showing kidneys excreting contrast
KUB
Claudication is due to _____ in the _____.
Artherosclerosis, leg arteries
In long film aorto-iliac-femoral bilateral arteriography film density usually increases from pelvis, to thigh, to calf. Check what techniques are used to even out the exposure of longboard films
Step wedge at cone of tube
Slower speed calf film
Stepping tables for adult femoral arteriography usually step in ____ inch incriments
8-12
An alternate method of vascular entry for abdominal aortography is the translumbar approach. In this method where is the translumbar puncture made?
Below 12 rib, 10 cm to left of the backbone
Which medication maybe used to increase visualization of a portal venous system or during a splenic arteriogram?
Tolazoline
A young woman has attacks of intermittent vasospasm in both of her hands when exposed to cold or if she becomes emotional. Her fingers become white, numb and painful. These signs and symptoms are most likely due to
Raynaud’s disease
Artery in the shoulder area
Axillary
Artery in the humorous area
Brachial
Artery in the forearm- thumb side
Radial
Artery in forearm- pinkie side
Ulnar
Artery in thorax- beneath clavicle
Subclavian
For filming pulmonary angiograms the large cut-film method has advantages over cine-angiograms which are
Higher resolution
Field size can include the entire lung
Where is the oily contrast medium used in lymphangiography eventually filtered out by the body?
By the lungs
Check the angiographic features most specific to pulmonary embolism.
Abrupt vessel cut off
Intralumen filling defects
A patient with an occluded rt internal common carotid artery may not have signs of a stroke or TIA because of
Circle of Willis arterial anastomosis
Severe stenosis of an internal carotid artery may lead to a delayed flow through a long thin vessel. this is termed
String sign
The gold standard diagnostic tool for pulmonary embolism is
Pulmonary angiography
Check the hemodynamics findings associated with massive pulmonary embolism
IV septum bulges into LV
Reduced LV filling volume with reduced CO
In a patient with hypertension due to pheochromocytoma, arteriography maybe used to visualize the tumor which is within the
Adrenal gland
You are assisting on a long leg bilateral arteriogram on an adult patient with minimal distal occlusive disease. How would you program the injector for a Hypaque 60% injection through a six French catheter at the aortic bifurcation?
12/s for 80
