Q-1. Which artery is dissected most commonly following arteriography by femoral route?
a) Celiac trunk
b) Superior mesenteric artery
c) Inferior mesenteric artery
d) Gastro-duodenal artery
Answer: Inferior mesenteric artery
Explanation:
Highest percentage of dissection following arteriography by femoral route:
Inferior mesenteric artery > Gastro-duodenal artery > Celiac trunk > Superior mesenteric artery
Arterial dissection in arteriography can occur either during femoral puncture (most common artery- external iliac artery) or during catheter manipulation (most common artery- internal iliac artery).

Q-4. Central dot sign is seen in?
a) Primary sclerosing cholangitis
b) Liver Hamartoma
c) Caroli’s disease
d) Polycystic liver disease
Answer: Caroli’s disease
Explanation:
Caroli’s disease is a congenital disorder comprising of multifocal cystic dilatation of segmental intra-hepatic bile ducts.
It is also classified as a type V choledochal cyst, according to the Todani classification.
Radiographic features:
Ultrasound:
May show dilated intra-hepatic bile ducts (IHBD)
Intra-ductal bridging: echogenic septa traversing the dilated bile duct lumen
Small portal venous branches partially or completely surrounded by dilated bile ducts1, 3.
Intra-ductal calculi
CT scan:
Multiple hypo-dense rounded areas which are in-separable from the dilated intra-hepatic bile ducts
“Central dot” sign: enhancing dots within the dilated intra-hepatic bile ducts, representing portal radicles 1

d) Increased flow in upper lobe veins
Answer: Oligemic lung fields
Explanation:
Radiological features of left ventricular heart failure:
Upper lobe venous distention
Kerly B line
Peri-hilar haze
Bronchial cuffing
Airspace opacities
Peripheral bat wing distribution
