Note:—SBP indicates systolic blood pressure; DBP, diastolic blood pressure; MAP, mean arterial blood pressure. 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).
