♦ 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.

Background: Imaging plays a major role in the detection, diagnosis, and ultimate treatment strategies of adnexal masses. As high as 10% of women in the United States undergo surgical evaluation for a suspected adnexal neoplasm. Objective: To understand the advantages and disadvantages of each imaging modality used in the evaluation of adnexal masses. Results: Ultrasound is frequently the imaging modality of choice for initial characterization. Computed tomography, magnetic resonance imaging, and positron emission tomography – computed tomography are frequently employed if malignancy is suspected to assess for metastasis. Conclusion: A basic understanding of adnexal imaging modalities will be of benefit to care providers and, in turn, be of benefit to patients.

Bone Sarcomas

Identification, staging, and treatment of bone sarcomas rely on both clinical and imaging evaluations. Although conventional radiography remains the primary imaging modality for characterizing bone tumors, bone scintigraphy, computed tomography, magnetic resonance imaging, and positron emission tomography can each add information for staging and treatment planning.

Longitudinal Imaging

Non-invasive longitudinal imaging of osseointegration of bone implants is essential to ensure a comprehensive, physical and biochemical understanding of the processes related to a successful implant integration and its long-term clinical outcome. This study critically reviews the present imaging techniques that may play a role to assess the initial stability, bone quality and quantity, associated tissue remodelling dependent on implanted material, implantation site (surrounding tissues and placement depth), and biomarkers that may be targeted. An updated list of biodegradable implant materials that have been reported in the literature, from metal, polymer and ceramic categories, is provided with reference to the use of specific imaging modalities (computed tomography, positron emission tomography, ultrasound, photoacoustic and magnetic resonance imaging) suitable for longitudinal and non-invasive imaging in humans. The advantages and disadvantages of the single imaging modality are discussed with a special focus on preclinical imaging for biodegradable implant research. Indeed, the investigation of a new implant commonly requires histological examination, which is invasive and does not allow longitudinal studies, thus requiring a large number of animals for preclinical testing. For this reason, an update of the multimodal and multi-parametric imaging capabilities will be here presented with a specific focus on modern biomaterial research.

Purpose: Central venous catheter insertion for acute trauma resuscitation may be associated with mechanical complications, but studies on the exact central venous catheter tip positions are not available. The goal of the study was to analyze central venous catheter tip positions using routine emergency computed tomography. Methods: Consecutive acute multiple trauma patients requiring large-bore thoracocervical central venous catheters in the resuscitation room of a university hospital were enrolled retrospectively from 2010 to 2015. Patients who received a routine emergency chest computed tomography were analyzed regarding central venous catheter tip position. The central venous catheter tip position was defined as correct if the catheter tip was placed less than 1 cm inside the right atrium relative to the cavoatrial junction, and the simultaneous angle of the central venous catheter tip compared with the lateral border of the superior vena cava was below 40°. Results: During the 6-year study period, 97 patients were analyzed for the central venous catheter tip position in computed tomography. Malpositions were observed in 29 patients (29.9%). Patients with malpositioned central venous catheters presented with a higher rate of shock (systolic blood pressure <90 mmHg) at admission (58.6% vs 33.8%, p = 0.023) and a higher mean injury severity score (38.5 ± 15.7 vs 31.6 ± 11.8, p = 0.041) compared with patients with correctly positioned central venous catheter tips. Logistic regression revealed injury severity score as a significant predictor for central venous catheter malposition (odds ratio = 1.039, 95% confidence interval = 1.005–1.074, p = 0.024). Conclusion: Multiple trauma patients who underwent emergency central venous catheter placement by experienced anesthetists presented with considerable tip malposition in computed tomography, which was significantly associated with a higher injury severity.

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.
