Ultrasound results are usually available in less than half an hour. In the past, when ultrasound examinations were done, due to the relatively small number of medical technicians and the backward computer printing technology, ultrasound instruments were not equipped with printing systems, and they were handwritten paper reports, and doctors wrote the diagnosis results by hand after examining a patient, so it took a long time. With the development of computer printer technology, the color ultrasound instruments are now equipped with workstations and technicians specialized in printing results, and there is a template for each kind of lesion. If the area examined is normal, just fill in the measured values and the report comes out with it when the doctor finishes examining the patient. If the condition is more complex, the doctor will specifically add more descriptions, and the report will usually be issued in less than half an hour. In case of emergency, the report will take no more than 10 minutes to be issued to avoid delaying the condition and treatment.
