1. describe the finding
2. assess the meaning of findings (normal vs anomaly)
3. request further imaging if necessary
4. process information into meaningful interpretation (report/notes)
4 steps for dental interpretation
the determination of which of two or more diseases with similar symptoms the patient has
differential diagnosis
