 Title: "ValueSet: Imaging Procedure Type"
 Description: """
-This value set includes all imaging procedure types defined in SNOMED CT. The codes represent
-combinations of the modality to be used and the procedure to be performed.
+This value set includes imaging procedure types combining the LOINC/RSNA Radiology Playbook value set (`http://loinc.org/vs/loinc-rsna-radiology-playbook`) for the radiology imaging exams (e.g. "CT Abdomen and Pelvis W contrast IV") and SNOMED CT for image-producing procedures that are not radiology exams, namely endoscopic procedures (e.g. bronchoscopy, colonoscopy) and camera-/photography-based imaging (e.g. ophthalmic fundus and slit-lamp photography). The value set is intended to be used in the context of the EHDS Imaging Report implementation guide.
