Estimates of glomerular filtration rate from MR renography and tracer kinetic models.
PURPOSE To compare six methods for calculating the single-kidney glomerular filtration rate (GFR) from T(1)-weighted magnetic resonance (MR) renography (MRR) against reference radionuclide measurements. MATERIALS AND METHODS In 10 patients, GFR was determined using six published methods: the Baumann-Rudin model (BR), the Patlak-Rutland method (PR), the two-compartment model without bolus disp...
متن کاملGlomerular filtration rate measurements by dual-injection MR renography
Dynamic contrast-enhanced MR renography, analyzed with appropriate tracer kinetic models [1], is a promising technique for the non-invasive assessment of glomerular filtration rate (GFR). Dual-injection measurements, such as before and after administration of an angiotensin-convertingenzyme (ACE) inhibitor, have been proposed as an improved diagnostic marker of renovascular disease [2]. Technic...
متن کاملKidney function: glomerular filtration rate measurement with MR renography in patients with cirrhosis.
PURPOSE To assess the accuracy of glomerular filtration rate (GFR) measurements obtained with low-contrast agent dose dynamic contrast material-enhanced magnetic resonance (MR) renography in patients with liver cirrhosis who underwent routine liver MR imaging, with urinary clearance of technetium 99m ((99m)Tc) pentetic acid (DTPA) as the reference standard. MATERIALS AND METHODS This HIPAA-co...
متن کاملThe clinical utility of kinetic glomerular filtration rate
Background: In acutely unwell patients with rapidly changing renal function, estimating glomerular filtration rate (GFR) and predicting adverse renal outcomes are challenging and often inaccurate. Kinetic GFR (kGFR) is an estimate of immediate biomarker clearance derived from two discreet measurements that may better represent acute function. Our objective is to assess the clinical utility of k...
متن کاملNotable steps in obtaining improved estimates for glomerular filtration rate.
Knowledge of the glomerular filtration rate (GFR) is of crucial importance in the management of patients. In addition to a general evaluation of kidney function, a more precise assessment is valuable on many occasions, e.g., to detect early impairment of renal function, to allow correct dosage of drugs cleared by the kidneys, to monitor renal transplants, and to evaluate patients before use of ...
