No trauma——meet for patient requirement for health care

More detectable rate——decrease misdiagnosis

More accurate diagnosis

-- reduce wrong diagnosis

More quantitive information

–Increase estimation prognosis accuracy

–Assist making better therapy plan

More impersonality evidence——decrease law risk
