Single-kidney magnetic resonance renography

Summary Signal-time curves in individual kidneys measured using dynamic contrast-enhanced MRI. Data taken from supplementary material of Basak et al (2018), a study funded by Kidney Research UK. The dataset includes signal-time curves for aorta, left- and right kidney as well as sequence parameters and radio-isotope single kidney GFR values for 114 scans on 100 different subjects. This includes 14 subjects who have had a scan before and after revascularization treatment.

For those that had multiple visits, the value is either 'pre' (before treatment) or 'post' (after treatment). LK: signal curve in the left kidney (arbitrary units). RK: signal curve in the right kidney (arbitrary units). LK vol: volume of the left kidney (mL). RK vol: volume of the right kidney (mL). LK iso-SK-GFR: radio-isotope SK-GFR for the left kidney (mL/min). RK iso-SK-GFR: radio-isotope SK-GFR for the right kidney (mL/min). LK T1: precontrast T1-value of the left kidney (sec). RK T1: precontrast T1-value of the right kidney (sec). TR: repetition time or time between rf-pulses (sec) FA: flip angle (degrees) n0: number of precontrast acquisitions. field_strength: Magnetic field strength of the scanner (T) agent: Contrast agent generic name dose: contrast agent dose injected (mmol/kg) rate: rate of contrast agent injection (mL/sec) weight: participant weight (kg) Version history v0.0.4 Added single mini-pig dataset used in dcmri tutorial v0.0.3 Stable version used in dcmri examples pages
