20 MARCH 2011 committee report INTERPRETATION AND RESPONSIBILITIES • Persons who employ CB imaging must be familiar with all other imaging modalities, including MCT, MRI, ultrasound and nuclear medicine, which may be more appropriate. Under normal circumstances, CB imaging should not be prescribed solely on the basis of convenience, e.g., in-office CB units. • Persons carrying out the technical (performing the scan) aspects of imaging must have had appropriate training. • The clinician overseeing/obtaining the CB examination is responsible for appropriate radiologic interpretation of the study. • The entire volume data set from a CB study must be evaluated and interpreted. To varying extents, the majority of CB scans include the paranasal sinuses, pharyngeal air spaces, skull base, cervical spine and upper neck. • The minimum skill set required to interpret CB studies includes: -- A thorough understanding of the strengths and weaknesses of this modality. -- The ability to apply an appropriate algorithm for evaluating volume data. This is not the same as that used in interpreting 2D radiographs. The ability to perform morphologic analyses and plan surgical procedures is different from the skill set required to evaluate the data set for disease. -- Thorough knowledge of the radiologic anatomy of all structures included in the scan. This differs from clinical/surgical anatomy and that seen in plain 2D radiographic images. -- Knowledge of the pathoses and clinical significance of the various disorders which may affect all the structures included in the scan. -- Knowledge of and the ability to identify radiologic features which suggest presence of disease. Many abnormalities do not present as obvious opacities or lucencies. -- The ability to identify the key radiologic characteristics of a specific type of disease and the knowledge to interpret those radiologic characteristics so identified. This requires a thorough knowledge of the radiologic features of diseases affecting the orofacial structures. • Radiological reports should be provided for CB scans. • The radiological skill levels of clinicians involved in CB imaging as well as the associated ethical, insurance and medico-legal implications require consideration. If the practitioner is not able to comprehensively interpret CB datasets in their entirety or does not have suitable training, it seems prudent that arrangements should be made for this to be performed by radiologists with appropriate training and expertise in dental and orofacial imaging. Concerns have been raised for clinicians who issue disclaimers and those who obtain patient agreement to a waiver of liability with respect to the complete interpretation of CB studies for which the clinician is responsible. This paper does not address this issue. Legal advice is strongly recommended. Orofacial 3D cone beam (CB) imaging is an essential technique which all dental and orofacial clinicians must now be familiar with. However, rather than replacing other modalities, CB imaging complements plain 2D radiography, panoramic radiography, multislice computed tomography (MCT) and other techniques including MRI, ultrasound and nuclear medicine. This document is largely based on the recently published review paper Cone beam imaging: Is this the ultimate imaging modality? (Clin Oral Implants Res. 2010;21:1201-8). Members are encouraged to read this review. Bernard Koong Oral and Maxillofacial Radiologist On behalf of the Dental Instruments Materials and Equipment Committee ISO-18...
