Characteristics of Patients Undergoing Ferumoxytol‐Enhanced MRI
| Entire cohort (n = 217 unique cases) | Anesthesia only (n = 94) | Nonanesthesia cases (n = 123) | Bolus infusions (n = 104) | Slow infusions (n = 113) | |
|---|---|---|---|---|---|
| Age (range) | 3d–94y | 3d–86y | 12y–94y | 3d–94y | 3d–89y |
| Gender, % female | 43% (n = 93) | 45% (n = 42) | 41% (n = 51) | 40% (n = 42) | 45% (n = 51) |
| Weight, kg | 50.1 (9.9–73.4) | 12.6 (3.6–23.0) | 68.5 (52.2–81.4) | 59.4 (16.5–76.9) | 37.3 (3.2–70.4) |
| Creatinine (μmol/L) | 168.0 (61.9–282.9) | 53.0 (35.4–265.2) | 194.5 (132.6–291.7) | 168.0 (70.7–265.2) | 168.0 (53.0–282.9) |
| eGFR (mL/min/1.73m2) | 31 (18–56) | 41 (19 to ≥ 60) | 29 (18–43) | 32 (19–51) | 28 (17–58) |
Data are reported as median (interquartile range). For adults (age ≥ 18 years), the eGFR was derived from the MDRD (Modification of Diet in Renal Disease) equation (Levey AS et al. Ann Intern Med. 2009;150:604–612). For children (<18 years), the Bedside Schwartz equation was used to calculate eGFR (Schwartz GJ et al. J Am Soc Nephrol. 2009;4:1832–1843). d, days; eGFR, estimated glomerular filtration rate; y, years.
