Cone beam CT: non-dental applications
Initially Cone Beam CT was almost exclusively used to perform dental radiology. However, the first generation CBCT systems were later increasingly used to study sinuses, facial and nose fractures, temporomandibular joints etc. 3D-cephalometric head and neck studies became possible once CBCT systems were available that allowed scanning of the complete head. For this purpose a double rotation technique with stitching of the resulting two data sets was needed. CBCT systems on which the rotation could be stopped were needed to perform dynamic swallow or pharyngography studies. The advent of more powerful high-end CBCT systems led the way to temporal bone and skull base imaging. Finally, high-end “supine” CBCT systems using a “gantry” made small joint musculoskeletal imaging possible. These non-dental CBCT studies gradually replaced conventional X-rays and CT/MDCT studies because they allowed imaging with higher resolution, lower radiation dose and less metal artifacts. In this paper the most important non-dental CBCT indications will be discussed

Long-distance attachments and implications for tourism development: the case of the Western Ukrainian diaspora
This study analyzes the perspectives of roots tourism through the experiences of Western Ukrainian diaspora members. Their sense of attachment to the ancestral homeland and their visits to the places of origin are investigated, together with the views by tour operators specialized in roots tourism and public authorities dealing with tourism in the region, evaluating the actual or potential impact in terms of tourism development opportunities. The peculiar history of this territory makes it a distinct research target, with dynamics that are different from the rest of the country. The desire to turn Western Ukraine into a solid tourist destination and the aim of stimulating economic development in a region that is still struggling to re-emerge from its marginality are widespread and form a fertile basis for the growth of diaspora tourism as a solid asset. Lights and shadows emerge from the diaspora tourists’ experiences and perceptions. Specialized tour operators clearly see the enhancement of this form of tourism as an important business opportunity, while public authorities are not currently focusing on this segment, preferring general tourism promotion

Bilateral cervical spondylolysis
Background: A 42-year-old man, with no significant medical history, was admitted at the emergency department following a road traffic accident. While cycling, the patient had been hit by a car, after which he briefly lost consciousness. Upon admission, he complained of severe headache and pain in his left shoulder and thorax. Physical examination revealed stable vital parameters and a Glasgow Coma Scale of 15/15. There were no neurological deficits
Facial and dental trauma
Dental and facial trauma are very common in a daily routine radiology practice. Knowledge of the functional anatomy of the mandibulofacial and maxillofacial regions forms the cornerstone of a thorough full radiologic evaluation of the patient with a dental and/or facial trauma. Cone beam computed tomography and multidetector computed tomography are currently considered the imaging modalities of choice. There are several patterns and classification systems for the various subtypes of mandibulofacial and maxillofacial fractures. They are discussed separately in this article with special attention to the types of dental trauma and orbital trauma
