Table of Figures

Figures 1 and 2:
1) T1W MR imaging in a patient with liver cirrhosis before and after liver transplant.
2) Mean signal intensity of the globus pallidus before and after liver transplantation.
Figure 3:
MR imaging demonstration of massive brain edema in a patient with fulmiant hepatic failure and sever intracranial hypertension and coma.
Figure 4:
In chronic liver failure with portal-systemic shunting of blood there is an increase in the blood amonia that is incorporated to the astrocyte thereby increasing the concentration of Glutamine.
Figure 5:
¹H-MRS obtained from the parietal white matter in a healthy control an a cirrhotic patient.
Figure 6:
Serial ¹H-MRS obtained from parietal white matter from a patient with chronic hepatic failure before and after successful liver transplantation. There is progressive normalization of the ¹H-MRS pattern with increases in Ins and decreases in Glx.
Figure 7:
Myo-inositol (Ins/Cr) and Glutamine/Glutamate (Glx/Cr) indexes show progressive normalization after liver transplantation (p<0.001 and p=0.002).
Figure 8:
MTR maps in a cirrohtic patient. A diffuse decreased in signal can be appreciated in otherwise normal appearing white matter on T1W images.
Figure 9:
Serial MTR values before and after liver transplantation. Progressive normalization is demonstrated. (p<0.001).
Figure 10:
Fast-FLAIR MRI in a cirrhotic patient without overt hepatic encephalopathy shows a symmetrical high signal intensity along the cortico-spinal tract.
Figure 11:
Serial Fast-FLAIR MRI in three different cirrhotic patients before and after (1 month, 12 months) liver transplantation. There is progressive decrease in the high signal intensity that affects the cortico-spinal tract symmettrically.
Figure 12:
Serial changes in relative T2 (rT2) signal and MTR after liver transplantation. A significant correlation exists in the time course normalization between rT2 signal intensity and MTR.
Figure 13:
Axial T1WI before(a) and 12-months(b) after liver transplantation show an increase in ventricular volume.
Figure 14:
Serial changes in ventricular volume after liver transplantation. A significant increase is observed between baseline and 1 and 12 months, but not between 1 and 12 months.
Figure 15:
Fast-FLAIR and DW MRI in a patient with liver cirrhosis before (upper row) and 1 month after liver transplantation (lower row).
