: Background: High-impact trauma frequently leads to injuries of the orbit, but literature
focusing on the viscerocranium rather than the neurocranium is underrepresented. Methods: Retrospective cohort study (2006–2014) at an urban level 1 trauma center assessing the frequency and
typical patterns of orbital injuries on whole-body computed tomography (WBCT) with maxillofacial
multi-slice CT (MSCT) after severe trauma. (1) Screening of consecutive WBCT cases for dedicated
maxillofacial MSCT. (2) Examination by two independent experts’ radiologists for (peri-/)orbital
injuries. (3) Case review for trauma mechanisms. Results: 1061 WBCT were included revealing 250
(23.6%) patients with orbital injuries. Less than one-quarter (23.3%) of patients showed osseous
and 9.5% showed soft tissue injuries. Combined osseous and soft tissue lesions were present in
39.2% of orbital injuries, isolated soft tissue injuries were rare. Single- or two-wall fractures of the
orbit were prevalent, and the orbital floor was affected in 67% of fractures. Dislocated extraocular
muscles (44.6%), deformation of the ocular globe (23.8%), and elongation of the optic nerve (12.9%)
were the most frequently soft tissue findings. Vascular trauma was suspected in 15.8% of patients.
Conclusions: Orbital trauma was confirmed in 23.6% of cases with suspected facial injuries after severe
trauma. Concomitant soft tissue injuries should be excluded explicitly in cases with orbital fractures
to prevent loss of vision or ocular motility.
The Study of Health in Pomerania (SHIP), a population-based study from a rural state in northeastern Germany with a relatively poor life expectancy, supplemented its comprehensive examination program in 2008 with whole-body MR imaging at 1.5 T (SHIP-MR). We reviewed more than 100 publications that used the SHIP-MR data and analyzed which sequences already produced fruitful scientific outputs and which manuscripts have been referenced frequently. Upon reviewing the publications about imaging sequences, those that used T1-weighted structured imaging of the brain and a gradient-echo sequence for R2* mapping obtained the highest scientific output; regarding specific body parts examined, most scientific publications focused on MR sequences involving the brain and the (upper) abdomen. We conclude that population-based MR imaging in cohort studies should define more precise goals when allocating imaging time. In addition, quality control measures might include recording the number and impact of published work, preferably on a bi-annual basis and starting 2 years after initiation of the study. Structured teaching courses may enhance the desired output in areas that appear underrepresented.
