We all live in an age of science and technology. The appliances of science and technology have revolutionized our way of life. There is nothing that has influenced our lives more than a computer. There can not be any field that is devoid of the influence of computer applications. From agriculture to rocket science, computers have significant roles to play. The demand of computers has always been on the increase for some time in many fields.

             Among the fields that have made tremendous advances in the twentieth century due to the advent of computers, medicine stands out from the rest. Computers are used in medicine in almost all areas. Whether it is diagnosis, treatment, research or data management, computers have there own applications. Whatever we enjoy today in terms of our health may not be possible without the invaluable contribution of computers. Therefore, my endeavor is to discuss how significantly computers have contributed in the field of medicine.

             The Role of Computers in Diagnosis .

             Diagnosis helps to determine the nature of a disease. Without a proper diagnosis, a disease can not be treated effectively. Before the advent of computers, physicians merely guessed at what caused certain diseases. Consequently, many patients either ended up in getting treatment for something that they did not require treatment for or losing their lives. This unfortunate situation does not exist at all now. .

             Thanks to computers, physicians can diagnose a disease with astonishing efficiency nowadays. Modern diagnosis consists of three main steps. Taking of patient's health history, examining the patient physically and conducting laboratory or radiological examinations are the three main steps. In all three steps, computers are used invariably. Instead of guessing the causes for a disease, the physicians just have to enter the symptoms of a patient into the computers. With the help of artificial intelligence, they get a crystal clear picture of the disease.
