b.>/= 4-5mm

c .>/= 6-7mm

1.---b

2..Which anastomosis is done first in liver transplant

a.IVC anastomosis

b.portal vein anastomosis

c.hepatic artery anastomosis

d.duct-duct anastomosis

e.none

2..---a

"Weeping willow trees” appearance ?

Q..All are true regarding imaging finding in cirrhosis of liver except

a.flying bat pattern on scintigraphy

b.bone marrow uptake of radionuclide

c.corkscrew appearance of intrahepatic areteries on angiography

d.weeping willow trees appearance on hepatic venography

e.Hypointense T2W appearance of regenerative nodules

ANS.----d

“Weeping willow trees” appearance (hepatic vein branches getting close ) on hepatic venography is noted in idiopathic portal hypertension

HIPPOCAMPAL SCLEROSIS

Q.All are true regarding hippocampal sclerosis except

a. The amygdala remains superior to temporal horn

b.  the CSF signal in the uncal recess of temporal horn / the alveus seprate amygdale from hippocampus

c. Both amygdala and hippocampus are hypointense to gray matter on almost all  MR pulse sequences.

d.The hippocampus may be slightly hyperintense to gray matter on FLAIR images

e. the posterior hippocampal boundary for volumetry extend to the crus of the fornix  

ANS.----c

Both amygdala and hippocampus are isointense to gray matter on all MR pulse sequences. The hippocampus, however, may be slightly hyperintense to gray matter on fluid attenuated inversion recovery (FLAIR) images due to incomplete suppression of CSF
