"turbulent flow in a post-stenotic area"
"time of flight (TOF): whereby the high velocity of the blood jet at the level of stenosis appears as a loss of signal (black)"
"In some cases, renal impairment precludes the use of contrast due to the risk of nephrogenic systemic fibrosis 15; in such cases, TOF imaging is beneficial."

"ACE inhibitor scintigraphy"
"Ultrasound, although it is widely available, inexpensive, and often used first-line, is relatively operator-dependent, often artifact-affected (e.g. obesity, bowel gas artifact), and may be time-consuming 15."
"In some cases, renal impairment precludes the use of contrast due to the risk of nephrogenic systemic fibrosis 15; in such cases, TOF imaging is beneficial."
"the affected kidney with renovascular hypertension shows impaired function due to ACE inhibition; based on this principle, scintigraphy has been very useful for the diagnosis of renal artery stenosis"
"sequential images and scintigraphic curves are plotted for the renal cortex and pelvis; renal uptake is measured at 1-2 minute intervals after administering the IV injection"
"interpreted as either low, intermediate or high probability"
