What type of technetium is used in bone scans vs thyroid scans?
Bone scans: Tc bisphosphonate
Thyroid scans: Tc pertechnate
Which type of nuclear medicine test is most useful for identifying Ca cells themselves?
Which type of nuclear medicine test is most useful for identifying primary neuroendocrine tumours (eg insulinomas)?
Gallium 68 dotatate PET and CT (identifies somatostatin receptor)
Which type of nuclear medicine test is most useful for parathyroid scans?
Sesta MIBI scan
Which type of nuclear medicine test is most useful for investigating for a phaeochromocytoma?
MIBG (looks for phaeo mets)
Recall the timeline of elevation of troponin I, AST and LDH elevation post-MI
Troponin I - first few hours
AST - first day
LDH - over first 5 days
Which LFT result will be most deranged in obstructive jaundice?
Descrine the pathophysiology of alcoholic hepatitis causing portal hypertension
Alcoholic hepatitis --> hepatocyte death
The person becomes ill and recovers, and the hepatocytes regenerate. However, rather than regenerating as before, they form a NODULE
This nodule disrupts hepatic micro-architecture between the portal vein and the central vein
If enough nodules appear, this increases pressure in the portal vein --> portal HTN
