AbstractComputed tomography (CT) is considered the gold standard technique for the assessment of trauma patients with suspected involvement of the eye and orbit. These traumas can result in dramatic consequences to visual function, ocular motility, and aesthetics. CT is a quick and widely available imaging modality, which provides a detailed evaluation of the orbital bony and soft tissue structures, an accurate assessment of the globes, and is used to guide the patients’ treatment planning. For a timely and accurate diagnosis, radiologists should be aware of fracture patterns and possible associated complications, ocular detachments and hemorrhages, and different appearances of intraorbital foreign bodies. This educational review aims to describe all post-traumatic orbital abnormalities that can be identified on CT, providing a list of tips and a diagnostic flowchart to help radiologists deal with this complex condition.

An experimental study was performed to compare computed tomography (CT), magnetic resonance imaging (MRI), and real-time, high resolution ultrasonography (US) for the detection of wooden foreign bodies in muscle tissue. Wooden splinters were prepared, measured for size, soaked in saline, and placed in porcine muscle distant from and adjacent to bone. The specimens were then examined using roentgenography, CT and MRI in planes parallel and perpendicular to the splinters, and US. The largest wooden foreign bodies (minimum smallest width = 10 mm) were easily detected by CT, MRI, and US. Almost all splinters of various sizes, small and large, soaked in saline for 5 months were easily detected by MRI. Smaller splinters (minimum smallest width = 1–4 mm) soaked for only 3 days and placed distant from bone were most easily detected by US; those soaked for 5 months were most easily detected by either US or MRI. The smaller splinters soaked for only 3 days and placed near bone were not reliably detected by any of the imaging methods; CT and MRI were both more sensitive than US in this situation. MRI scanning was more sensitive perpendicular than parallel to the long axis of the splinters. Therefore, either US or MRI may be the best initial imaging modality for evaluation of a suspected wooden foreign body, depending on availability of imaging method, chronicity of symptoms, and proximity to bone.

Objective. We sought to describe the trend in abdominal CT use in adult trauma patients after a point-of-care emergency ultrasound program was introduced. We hypothesized that abdominal CT use would decrease as FAST use increased.Methods. We performed a retrospective study of 19940 consecutive trauma patients over the age of 18 admitted to our level one trauma center from 2002 through 2011. Data was collected retrospectively and recorded in a trauma registry. We plotted the rate of FAST and abdominal CT utilization over time. Head CT was used as a surrogate for overall CT utilization rates during the study period.Results. Use of FAST increased by an average of 2.3% (95% CI 2.1 to 2.5,P<0.01) while abdominal CT use decreased by the same rate annually. The percentage of patients who received FAST as the sole imaging modality for the abdomen rose from 2.0% to 21.9% while those who only received an abdominal CT dropped from 21.7% to 2.3%.Conclusions. Abdominal CT use in our cohort declined while FAST utilization grew in the last decade. The rising use of FAST may have played a role in the reduction of abdominal CT performed as decline in CT utilization appears contrary to overall trends.

♦ Each modality of imaging—digital radiography, multidetector computed tomography (MDCT), magnetic resonance imaging (MRI), ultrasound, and nuclear medicine studies—has its own advantages and disadvantages♦ Conventional radiography is the best for initial evaluation of a musculoskeletal problem♦ MDCT rapid survey of multiple trauma patients is easily performed using the new high speed computed tomography scanners♦ MRI is the imaging modality of choice for internal derangement of the knee and other soft tissue injuries♦ Radionuclide bone imaging is most suitable for screening the whole skeleton for metastases♦ Positron emission tomography is useful for identification of tumour, inflammation, and infection.

In view of the scarcity of literature data on the use of radiological imaging techniques in forensic veterinary medicine, while at the same time the number of reported crimes against animals involving the use of firearms is rising, this paper attempts to assess the usefulness of radiography and computed tomography (CT) in the post-mortem diagnosis of gunshot wounds (GSW) in comparison to classic necropsy. The design of the experiment was as follows: preparation of the research material (13 dog carcasses), shooting of the material from different distances (1.5 and 12 m, plus one contact shot to the head) and using different types of ammunition, followed by X-rays and CT scans in each case to examine the injuries resulting from the shot. The final steps of the experiment were photographic documentation and autopsy by the Virchow method. In the examined material, post-traumatic bone lesions and the presence of metallic foreign bodies were successfully imaged by both radiography and CT. GSW analysis using CT provided much better data quality and some additional information. Two general conclusions can be drawn from the results of the experiment. First, damage caused by gunshots is correlated with the calibre, initial velocity and kinetic energy of the projectile, as well as the distance from the muzzle of the gun to the object shot. Second, radiological examination is useful in preparing forensic veterinary opinions. Used as a complement to classic necropsy, they increase the possibility of an accurate post-mortem diagnosis of shooting victims.

Positron emission tomography with computed tomography (PET–CT) is an integral part of oncology practice in the current-day scenario. The hybrid anatomical and metabolic imaging information in this imaging modality provides access to a wealth of incidental findings which can have implications in the management of the patient, especially when surgical options are being considered. In this pictorial essay, we present incidentally detected mediastinal vascular anomalies on PET–CT, along with a review of associated literature.

Computed Tomography (CT) is the most commonly used imaging modality in the evaluation of cerebral hemorrhage in the head trauma patients. Objective: To study the incidence of a cerebral hemorrhage in traumatic patients using computed tomography. Method: This retrospective study was conducted at King Khalid hospital in Tabuk city, Saudi Arabia, in the radiology department, in the period from September 2018 to April 2020. The study was done by collecting 471 CT reports of patients all of them were exposed to head trauma with deferent reasons. The data were analyzed by Statistical Package for the Social Sciences (SPSS) program (ver. 20) and presented in tables and graphs according to the checklist which includes: patient age, gender, type of trauma, CT finding, and type of hemorrhage. Results: The most age group suffered from head trauma was less than 20 years percentage (55%), The male patients more exposed to head trauma than female patients with percentage (84.5%), the road traffic accident (RTA) is the most common type of trauma by percentage (63.5%), according to the CT finding; the cerebral hemorrhage represented (15.5%) with the highest percentage in a subdural hematoma (31.2%), the fracture represented (2.8%) while the normal appearance represented (81.7%) as the highest percentage. Conclusion: Most of the traumatic brain injury in patients caused cerebral hemorrhage and the CT scan reports show that: the common type of cerebral hemorrhage is subdural hematoma and it is common in males which exposed to (RTA) in the age group (21 - 40) years old.

Aims: In this study, we aimed to find the percentage of random pathologies and abdominopelvic region anomalies that are not related to trauma in pediatric patients. Background: An abdominal assessment of an injured child usually involves computed tomography imaging of the abdomen and pelvis (CTAP) to determine the presence and size of injuries. Imaging may accidentally reveal irrelevant findings. Objectives: Although the literature in adults has reviewed the frequency of discovering these random findings, few studies have been identified in the pediatric population. Methods: Data on 142( 38 female, 104 male) patients who underwent CTAP during their trauma evaluation between January 2019 and January 2020 dates were obtained from our level 3 pediatric trauma center trauma records. The records and CTAP images were examined retrospectively for extra traumatic pathologies and anomalies. Results: 67 patients (47%) had 81 incidental findings. There were 17 clinically significant random findings. No potential tumors were found in this population. Conclusion: Pediatric trauma CTAP reveals random findings. For further evaluation, incidental findings should be indicated in the discharge summaries.
