ABDOMINAL ULTRASOUND REGISTRY EXAM
SCRIPT 2026 QUESTIONS WITH ANSWERS
◉ Aneursym. Answer: Dilation of a segment of a vessel wall caused
by a weakness of all three layer s of vessel wall.
◉ Most common cause of aneurysm. Answer: atherosclerosis and
hypertension, can also be congenital, trauma ,infection, bacterial.
◉ What measurement diagnosis aortic aneurysm. Answer: AP
diameter >3 cm. measure from outer border to outer border. risk of
rupturing when >7cm.
◉ majority of AAA are located below where?. Answer: renal artery
◉ true aneurysm. Answer: dilatation involving all three layers.
tunica intima,media, and adventitia.
◉ clinical finding of true aneursym?. Answer: palpable pulsatile
abdominal mass, back and leg pain.
◉ fusiform (true AAA). Answer: most common type characherized
by spindle shaped dilatation.
,◉ saccular (true AAA). Answer: a focal out pouching of the vessel
wall. primarily caused by trauma or infection.
◉ berry (true AAA). Answer: small round outpouching 1-1.5 cm
found in cerebral vascular system. rupture causes death
◉ dissecting aneurysm (not true AAA). Answer: tear in the intima
layer of the vessel wall causing blood to collect between the intima
and media layer. there is a true lumen and false lumen.on US you see
pulsating intimal flap.
◉ pseudoaneurysm. Answer: tear in the vessel wall permits blood to
escape into surrounding tissue. occur from trauma or arterial
catheterization.
◉ IVC formed by confluence of.... Answer: right and left commen iliac
veins. IVC lies to rt of midline.
◉ major braches of IVC include.... Answer: Renal veins, Hepatic
veins, and Gonadal veins
◉ pathology that affects the size IVC. Answer: hepatomegaly,
pulmonary hypertension, and CHF(congestive heart failure) cause
dilatation of IVC.
,◉ most common tumor involved w/ IVC. Answer: renal cell
carcinoma (RCC)
-it may invade the renal vein and IVC.
◉ Renal Cell Carcinoma. Answer: most common on the rt kidney b/c
shorter distance to travel to enter into the ivc. (thrombus may be
noted.)
◉ LIVER. Answer: largest organ, Rt lobe 5-6x larger than lt lobe.
-covered by Glisson's capsule.
-main blood supplu portal vein.
-(15-17cm) less is normal
-greater than 15-17cm hepatomegaly.
◉ Riedel's lobe. Answer: normal varient where the is a
projection/extension of the rt lobe liver inferiorly.
-most common in women.
◉ from least echogenic to most echogenic. Answer: renal
sinus>pancreas>liver>spleen>renal cortex>renal medullary
pyramids.
, ◉ Couinard's system. Answer: uses hepatic veins and portal veins as
landmarks for divinding the liver into 8 segments.
◉ caudate lobe located... Answer: posterior superior surface of lt
lobe. (segment #1)
both the RHV & LHV drains the blood from caudate lobe
◉ Hepatic vein segments divides.... Answer: MHV-divides liver into
Rt and LT lobes
RHV-dvides rt lobe into ant & post
LHV-divides lt lobe medial & lateral segments
◉ Ligamentum Venosum. Answer: a remnant of the fetal ductus
venosus. Divides the caudate lobe from the left lobe. SEEN on US as
echogenic line
◉ Ligementum Teres (round lig). Answer: a remnant of the umbilical
veins. Divides the rt and lt lobe on the diaphragmatic surface.
◉ Falciform Ligament. Answer: Extends from umbilicus to
diaphragm and attaches the liver to the ant of abdominal wall.
◉ Coronary Ligament. Answer: contigous w/ the falciform lig. it
connects the posterior surface of liver to the diaphragm.
