Renal!

the __________ kidney is __________ than the _________

right, lower, left

the kidneys are located between the ____ _________ and ____ ____________ vertebrae

12th thoracic, 3rd lumbar

the primary function of the kidney is to?

filter the blood by removing waste products, excess water, and toxins

nephron

functional unit of the kidney

a nephron contains a ___________ and __________

glomerulus and tubules

glomerulus

tiny blood vessels where filtration happens

tubules

process filtered material and form urine

glomerular filtration

happens in the glomerulus, only small molecules can pass, keeps normal proteins and cells

tubular secretion

happens in the tubules, moves larger materials from blood into urine

the kidneys recieve alot of blood, about _____ to _____ % of cardiac output!

20 - 25%

the total renal blood flow is?

1.2L/min

of the 1.2L/min, about ______ % is ________, which is about ______mL/min

50% is plasma, 500mL/min

of the 500mL/min, 20% of that is plasma that passes through the tubules, which is about ___________

120mL/min

TRBF

total renal blood flow, 1.2L/min

ERPF

effective renal plasma flow, 500mL/min

GFR

glomerular filtration rate, 120mL/min

renal imaging is performed to: evaluate renal ____________, function __________ of ___________/_________ kidneys, and evaluate the ____________/__________

perfusion, native/transplanted, structure/location

indications (generally) for renal imaging

hydronephrosis, reflux, renal transplant evaluation

what imaging agent used for tubular secretion?

MAG3

what does MAG3 stand for?

mercaptoacetyltriglycine

what is the MOL for MAG3?

active transport, 80% tubular, 20% glomerular

with MAG3, _______ to _______% of the tracer is extracted from the blood during each pass through the kidneys

40 to 50%

PRO of MAG3?

better for patients with poor renal function, low cost, better image quality
