The absence of abnormal blood flow signals in the pelvis generally means that the blood flow in the female pelvis is in a normal state. When undergoing imaging examination, the state of blood flow in normal state will generally be indicated by certain signals, at which time the imaging examination equipment will determine the state of blood flow by detecting the signals of blood flow, so as to assess the state of the female pelvis. Therefore, if there is the presence of a tumor or abscess in the pelvis, the normal blood flow will be altered, at which time the imaging examination will show abnormal blood flow signals. Therefore, the absence of obvious abnormal blood flow signals in the pelvis means that the woman’s pelvis is normal blood flow, which still needs to be judged under the guidance of the doctor in conjunction with the specific situation.
