| Rule name | Source terms (search current study for these terms) | Matching terms (search for related studies containing these terms) | Explanation |
|---|---|---|---|
| Foot | Footfoot, feet | Foot, feet, ankle, lower extremity, tibia, fibula, calcaneus, knee | For studies of the foot, we could see relevant anatomy on a variety of other exams, possibly even the knee. So the matching list is broad in this case. |
| Head | Headhead, brain | Head, brain, facial, orbits, IAC%, temporal | Same considerations apply for head CTs. Current studies of the head are likely labeled as either 'brain' or 'head' so this suffices for source terms. The matching terms are similarly broad to search for studies with potentially relevant anatomy. |
| Chest | chest | chest, cxr, thoracic, pulmonary, aortic, nodule, TB | Similar to above |
