Advanced medical tests save lives every day -- but a new study suggests they haven't replaced a doctor's touch.
A new Loyola University study found that doctors' bedside exams did a better job than CT scans in predicting post-surgery complications.
In a study of 251 brain surgery patients, researchers found doctors' exams detected serious problems ten times -- three of which were bad enough to require additional surgery.
None of the CT scans done on the same patients predicted any problems.
Researchers say scanning technology is vital -- but using them without a doctor's input isn't necessarily helpful.
