  1. Portal Triad
    Common Bile Duct, Hepatic Artery, Portal Vein (Mickey Mouse in trans)

  2. cystic duct
    joins the gallbladder to the common bile duct
  3. common hepatic duct
    bile duct system that drains the liver into the common bile duct
  4. porta hepatis
    • portal vein, hepatic artery, common bile duct
    • same components of the portal triad but within the liver
  5. hepatofugal
    flow away from the liver (veins, bile)
  6. hepatopedal
    flowing towards the liver (arteries)
  7. Falciform Ligament
    seperates the left and right lobes of the liver and attaches to the diaphragm
  8. ligamentum venosum
    • remnants of the ducts venosus in the liver (shunt in the liver when a fetus)
    • by the caudate lobe
  9. Ligamentum teres
    • remnant of the umbilical veein
    • within the falciform ligament
    • by the quadrate lobe
  10. round ligament
    same as ligamentum teres
  11. Caudate Lobe
    • Above the porta hepatis
    • right is the IVC
    • Left is the fossa for ductus venosus
    • in the right lobe, superior portion
  12. Ampulla of Vater
    where the common bile duct and the pancreatic duct connects to go to the intestine
  13. Sphincter of Oddi
    small muscle that guards the ampulla of vater
  14. Spiral Valves
    in the neck of the GB
  15. Fundus
    is the top portion of the GB
  16. Duct of Wirsung
    • largest duct of pancreas that drains the tail, body, and head of the gland
    • joins the common bile duct to enter the duodenum through the ampulla vater
  17. Duct of Santorini
    • small accessory of the pancreas found in the head of the gland
    • by passes the Ampulla of Vater straight to the duodenum, not everyone has it
  18. Gerota's Fascia
    another term for the renal fascia (pararenal fat)
  19. Morison's Pouch
    • common place for ascites in the peritoneal cavity
    • between the right kidney and liver
  20. Hilum
    of the kidney is where the RV, RA, ureters enter the body of the kidney
  21. Hemangioma
    (liver) bright hyperechoic, tumor of capillaries, usually don't change in size
  22. sludge
    gallbladder, crystallization within the bile without stone formation, lack shadowing
  23. Cholelithiasis
    stone with in the gallbladder
  24. Choledocolithiasis
    stones within the CBD
  25. Metastases
    cancer that does not stay in one spot
  26. cirrhosis
    • is a concequence of chronic liver disease characterized by replacement of liver tissue by fibrotic scar tissue as well as regenerative nodules, leading to progressive loss of liver function
    • most commonly from ascites
  27. simple cyst
    anechoic on pictures, with enhancement
  28. hydronephrosis
    kidney cannot drain into the ureter causing a backup in fluid, causes enhancement and atrophy in the kidney
  29. Describe how the direction of blood flow determined by Doppler?
    • BART (normal)- blue away, red towards
    • RABT- red away red towards
    • (depends on the color bar)
  30. Trace the excretion of the bile through the biliary system to the duodenum.
    • Liver to the hepatic duct
    • Gallbladder to the cystic duct
    • Those two ducts form the common bile duct
    • The pancreatic then joins to make the ampulla of vater through the spuincter of oddi to the duodenum
  31. Vascular landmarks of the pancreas
    IVC, AO, splenic vein, PC, SMA
  32. List the echogenisities:
    renal capsule
    sinus, pelvis, collecting system
    cortex
    medulla, pyramids
    • capsule- hyper
    • sinus, pelvis, collecting system- hyper
    • cortex- medium/ hypo
    • medulla, pyramids- hypo
