A

MRI CHOLANGIOPANCREATOGRAPHY

36
Q

a known toxin causing cellular damage

A

alcohol

37
Q

as alcohol cant be stored in the body, what processes does the liver need to do?

A

the liver must convert it through oxidation, to alcohol dehydrogenase, acetaldehyde, and acetate, all of w/c to reduce cellular function

38
Q

this is the most frequent early response to alcohol abuse

A

fatty liver

39
Q
  • Fatty infiltration may be demoed by
A

ct/sonography

40
Q

In CT scan, a liver is considered to be fatty if…

A

its HU is equal to the HU of the spleen (Under normal circumstances, the liver should appear light-gray and the spleen dark gray)

41
Q

who is prone to fatty liver disease?

A
  • Obsess individuals w/ type 2 diabetes mellitus, metabolic syndrome, HYPERLIPIDEMIA
42
Q
  • Chronic liver condition in w/c liver parenchyma & architecture are destroyed, fibrous tissue is laid down, & regenerative nodules are formed
A

liver cirrhosis

43
Q

what is ascites

A
  • Accumulation of fluid w/in the peritoneal cavity
44
Q
  • Seen as a result of portal hypertensions & the leakage of excessive fluids from the portal capillaries
A

ascites

45
Q
  • Acute inflammation of the gallbladder
A

cholecystitis

46
Q

symptoms of cholecystitis

A

a sudden onset of pain, faver, nausea, vomiting

47
Q

cholecystitis is common in?

A

individuals w/ chronically symptomatic cholelithiasis

48
Q

what modality demoes cholecystitis the best?

A
  • CHOLESCINTOGRAPHY
49
Q
  • Inflammation of the pancreatic tissue
A

pancreatitis

50
Q
  • One of the most complex & clinically challenging disorders of the abdomen & is classified as acute/chronic, accdg. To clinical, morphologic & histologic criteria
A

pancreatitis

51
Q

what are the causes of pancreatitis

A
  • Causes include excessive & chronic alcohol consumption, obstruction of the hepatopancreatic ampulla by a gallstone or tumor & even the injection of contrast media during ERCP
52
Q
  • Yellowish discoloration of the skin & whites of the eyes, is not a disease itself but rather a sign of disease
A

jaundice

53
Q

what’s the difference between medical and surgical jaundice?

A

MJ - non-obstructive; occurs because of hemolytic disease, in w/c too many RBC are destroyed/ because of liver damage from cirrhosis or hepatitis

SJ - obstructive; occurs when biliary system is obstructed & prevents the bile from entering the duodenum. A common cause of this obstruction is blockage of the CBD caused by stones/masses
