6 Nuclear radiation imaging:
such as PET scan, which is used to diagnose diseases such as cancerous tumors.
7 Endoscopic diagnosis:
such as gastrointestinal endoscopy and cardiac endoscopy, which allow direct images of internal organs and tissues to determine the condition.
. These are some common steps in the medical diagnosis process, and procedures may vary based on the type of health problem and the individual condition of the patient.
