- Fig 1.
Temporal change of vital signs relative to a baseline values, before, during, and after imaging in 14 normal subjects. Mean values are indicated as solid diamonds with standard error bars. Y axis values indicate the change in the vital sign value relative to baseline mean obtained before scanning. Numbers in parentheses indicate total number of subjects at corresponding time spots. A, SBP; B, DBP; C, MAP; D, HR; E, O2 saturation.
- Fig 2.
Temporal change of vital signs relative to a baseline values, before, during, and after imaging in 46 subjects with neurologic disease. Mean values are indicated as solid diamonds with standard error bars. Y axis values indicate the change in the vital sign value relative to baseline mean obtained before scanning. Numbers in parentheses indicate total number of subjects at corresponding time spots. A, SBP; B, DBP; C, MAP; D, HR; E, O2 saturation.

Intergroup comparison was performed by Student t-text.
* Respiratory rate change in disease group before and after imaging is significant by paired t test (P < .001).
† Heart rate change in normal group before and after imaging is significant by paired t test (< .001).
