This renal artery is longer than the other
what's the right renal artery?
100
The first branch of the Aorta

True or False?
False

Bilateral Carotid exam showed:
Damped and low velocity waveforms bilaterally in all the carotid system
Where is the problem?
Cardiac. Probable aortic valve disease. Know the patient history.

RI=.8
Abnormal RI in the intrarenal vessel
400
The most reliable plane for the Aorta measurement
Transverse, AP and width

RI < 0.75
Normal acceleration time
Normal findings in the Intrarenal vessels
