Bone Tumors of the Jaw – the "Blind Spot" for Radiologists Experienced with Tumors? – Part II

Thomas Grieser, Edgar Hirsch, Ninette Tödtmann

Primary bone tumors of the jaw account for around 2% of all bone tumors in the human body - making them a rarity. The radiologist has the challenge of detecting, describing and classifying jaw tumors. This is made more difficult by the fact that maxillomandibular bone tumors differ in many respects from bone tumors in the rest of the body. It is often only possible to approximate the diagnosis, but this can be helpful in narrowing down possible entities. T. Grieser et al. discuss - based on the current WHO classification of odontogenic and maxillofacial tumors - selected and typical tumor entities illustrated with extensive pictorial material.

Standardized diagnosis of gastrointestinal tumors: an update regarding the situation in Germany

Mirjam Gerwing , Inka Ristow , Saif Afat et al.

The Purpose of research was to evaluate the current status of the diagnosis of gastrointestinal tumors in Germany by means of a survey of the oncological imaging working group of the German Radiological Society (DRG). An online survey was conducted via various DRG distribution lists in order to reach the largest possible group of radiologists in outpatient and inpatient care. In addition to requesting demographic data such as the place of work, questions were asked regarding the locally established imaging modalities and the CT protocols used, including oral/rectal contrasting in the diagnosis of oesophageal, gastric and colorectal cancer.
