"Yingying." Shang Siling raised another question, "Doctor Li says they need to redo the ultrasound and CT. Why do they need to redo tests that were just done at the Provincial People's Hospital?"
This is a question many ordinary folks can't understand: why hospitals don't recognize each other's test results.
For example, the ultrasound results are greatly affected by the skills and techniques of the ultrasound doctor. Clinical doctors trust their own hospital's ultrasound doctors, but are uncertain about those from other hospitals. In such cases, they need to redo the tests at their own hospital to ensure there were no mistakes or omissions in previous tests at other hospitals. Similarly, CT scans require the skill of radiologists; it's not as simple as patients think, a machine simply scanning the body. Doctors need to adjust scanning parameters based on the patient's situation, and their experience is crucial when synthesizing CT images, such as adjusting contrast.
