Distribution of physiologic indices in patients who had FE‐MRI exams and GE‐MRI exams. Data reflect values immediately preinjection (pre‐inj), immediately postinjection (post‐inj), and 30‐minute postinjection of ferumoxytol or gadofosveset. Whiskers represent data within the lower and upper 1.5 IQR. The bottom and top of the box represent the first and third quartile, while the band within the box represents the median. A: The HR (bpm), mean arterial blood pressure (MAP, mmHg), and pulse oximetry (%) distribution of all patients (n = 94, ages 3 days to 86 years, 36% female) undergoing FE‐MRI. Variations in HR (P = 0.12, 95% CI 93–106 bpm), MAP (P = 0.92, 95% CI 49–57 mmHg), and pulse oximetry (P = 0.68, 95% CI 95–98%) were not statistically significant. B: The HR, MAP, and pulse oximetry distribution between a comparable group of patients undergoing FE‐MRI (n = 23, ages 3 days to 13 years, 43% female) and GE‐MRI (n = 23, ages 2 days to 12.6 years, 43% female) under general anesthesia. Between‐group variations were not statistically significant (HR [P = 0.69, 95% CI 96–113 bpm], MAP [P = 0.74, 95% CI 44–52 mmHg], pulse oximetry [P = 0.76, 95% CI 94–98%]). All patients were examined under general anesthesia. bpm, beats per minute; HR, heart rate; MAP, mean arterial blood pressure.
