The T2 effect predominates and is only visible at high concentrations, for example in the bladder after renal excretion. Perfusion MRI also exploits the magnetic susceptibility effect due to the first intravascular passage of a concentrated bolus of Gadolinium chelate, responsible for a drop in the ...

However, since 2014, numerous studies have been published that reported finding evidence of gadolinium deposition in neural tissues in patients with normal renal function. (more…) Tweet Share MRI brain signal changes reported in a child November 22, 2015 8:04 pm / Leave a comment The ...
3-16). Delayed images may be helpful in further characterizing focal abnormalities, and images obtained during the renal excretory stage may be used to evaluate the urinary tract. Box 3-1 provides a list of potential indications for use of IV gadolinium chelates for abdominal and pelvic MRI. ...
