Description

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.

Format

dmr format - a folder with three csv files: 

  • data.csv: a data dictionary
  • rois.csv: a table with ROI curves
  • pars.csv: a table with parameters in long format

Available data

Each subject has the following data:

  • subject: unique study ID of the participant
  • time: array of time points in sec
  • aorta: signal curve in the aorta (arbitrary units)
  • visit: for participants that had just a single visit, this has the value 'single'. 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)
