RATIONALE AND OBJECTIVES Radiolabeled ortho-iodohippurate is commonly employed for evaluating effective renal plasma flow (ERPF) by means of either in vivo scintigraphy and/or plasma clearance curves. A new method has recently been developed for measuring levels of stable iodine (iodine-127) in biologic samples, based on the detection of x-ray fluorescence photons. In this study, the authors assessed the potential of the new system to evaluate ERPF by using an iodinated contrast medium with… Expand

Measurement of renal function with iohexol. A comparison of iohexol, 99mTc-DTPA, and 51Cr-EDTA clearance.
TLDR
It is concluded that measurement of io hexol clearance provides information about GFR that is as valid as measurements of 51Cr-EDTA and 99mTc-DTPA clearance, and it is possible to perform urography and a determination of GFR using a single injection of iohexol. Expand
Comparative evaluation of urographic contrast media, inulin, and 99mTc-DTPA clearance methods for determination of glomerular filtration rate in clinical transplantation.
TLDR
Contrast clearance determination utilizing the slope-intercept method is accurate, safe, pragmatic, and more precise than serum-creatinine and endogenous- Creatinine clearance for measurement of renal function in clinical transplantation. Expand

TLDR
HPLC purified MAG3 behaved similarly to OIH under adverse physiologic conditions and the data continue to support the use of MAG3 as a potential clinical substitute for OIh. Expand
Renal radiopharmaceuticals--an update.
TLDR
With the detailed validation and increasing recognition of the clinical utility of several of the radionuclidic procedures at many centers, it is hoped that radion UCLA assessment of renal disorders ultimately will be made available routinely at all medical facilities. Expand
Estimation of glomerular filtration rate from low-dose injection of iohexol and a single blood sample.
TLDR
Glomerular filtration rate can be reliably determined with a low dose of iohexol and a single blood sample obtained three hours after the injection in persons with normal serum creatinine, and is a good alternative to the methods using radiopharmaceuticals. Expand
Quantitation of renal function with glomerular and tubular agents.
TLDR
Estimation of ERPF with radioiodinated OIH and GFR with 99mTcDTPA can be achieved in many ways, all of which yield clinically useful results, and the preference at the present time is to use a single or double plasma sample to calculate global ERPF or GFR. Expand

TLDR
It is suggested that an important factor in the decrease in GFR is the rise in pressure in the renal tubules at the start of a diuresis, before they have had time to dilate. Expand
Effects of Contrast Agents on Renal Function
TLDR
Changes in renal blood flow, glomerular filtration rate, urinary electrolyte and solute excretion, and modification of the urinary concentrating-diluting mechanisms have yielded insights into the tubulo-glomerular actions of contrast media. Expand
Accuracy and reproducibility of a new contrast clearance method for the determination of glomerular filtration rate.
TLDR
A new method using an x ray fluorescence technique to measure disappearance from the plasma of injected non-ionic iodinated contrast media merits further study and might find a useful place in routine clinical practice. Expand
Measurement of the plasma clearance of urographic contrast media for the determination of glomerular filtration rate.
TLDR
The contrast clearance technique for the measurement of glomerular filtration rate during excretory urography is simple, quick and accurate, and merits further development. Expand
