View larger version (37K): [in a new window]   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.
