Study summary

Comparison of renal blood flow measurements by PAH clearance and MRI

Read the detailed description

The traditional measurement of renal blood flow in ml/min involves the collection of multiple blood and urine samples after an infusion of a drug called para-aminohippurate (PAH) is given. In this study, the investigators determine the ability of MRI to estimate renal blood flow. The primary hypothesis is that renal blood flow as measured by PAH clearance is similar to renal blood flow as estimated by MRI. The measurements by PAH clearance and MRI are both performed on the same day.

Inclusion criteria

In this study, the investigators will enroll 16 men and women aged ≥ 18 years with Stage II - V chronic kidney disease (CKD). In addition, the investigators will enroll 4 subjects with a glomerular filtration rate (GFR) of greater than 60 ml/min who do not have any evidence of CKD.

Study arms

  • Placebo comparator
    PAH

    PAH measure of renal blood flow is first performed on subjects prior to administration of furosemide

    Other: Placebo

  • Active comparator
    MRI after furosemide

    After the PAH measurement is complete, subjects receive 20 mg furosemide and undergo BOLD MRI to estimate renal blood flow

    Drug: Furosemide

Interventions

  • DrugFurosemide

    Renal blood flow is measured after the administration of 20 mg of furosemide during MRI scan only.
