What's The Importance Of Computer In Medical Science?

Instantaneous transmission of information and calculations for checking tests. Between states/cities/countries. Just one of the many reason.like they use on csi(yes a tv show) they use a computer to test the smallest trace and spit out a complete analysis in minutes instead of days like the dr's office/testing labs use to. Or let's go into  doing surgical assisted operations by computer from another state/the surgeon is not even in the same hospital while assisting or giving input form another state or country.or how about looking through vast amounts of medical libraries information by simply putting in the phrase or symptoms of a illness and getting back the probable treatments. I am not even in the(know nothing of medicine) medical field but have learned this from tv/pbs/doctors shows. Or what about transplant searches being done from one terminal and being able to find a organ within minutes within the hospitals/transplant organizations. I know your asking about science -so i would say speed of information is the biggest importance being able to do what use to take days,months,years to do is now being done in minutes and hours.
