It is now generally accepted that nontraumatic back pain in the pediatric population is common. The presence of isolated back pain in a child has previously been an indication for imaging; however, recently a more conservative approach has been suggested using clinical criteria. The presence of constant pain, night pain, and radicular pain, alone or in combination, lasting for 4 weeks or more, constitute clinical red flags that should prompt further imaging. Without these clinical red flags, imaging is likely not indicated...

Bethany Richards, James Riley, Adnan Saithna
A high rate of suboptimal shoulder radiographs was identified during a service evaluation exercise in our orthopaedic outpatient clinics. Inadequate radiographs require a return to the radiology department for further imaging, a resultant increased workload, delays in the clinic, increased radiation for patients, and inconvenience and decreased patient satisfaction. Furthermore, if a sub-optimal radiograph is accepted there is concern that diagnoses may be missed. The aim of this project was to decrease the rate of suboptimal radiographs by delivering a teaching package directed towards quality improvement...

COMPARATIVE STUDY
Benjamin M Kaye, Susanne A E B Boroffka, Annika N Haagsman, Gert Ter Haar
Tracheal hypoplasia is commonly seen in English Bulldogs affected with brachycephalic airway syndrome. Previously published diagnostic criteria for tracheal hypoplasia in this breed have been a radiographic tracheal diameter:tracheal inlet ratio (TD:TI) < 0.12 or a tracheal diameter:third rib diameter ratio (TD:3R) < 2.0. Computed tomography has become increasingly used for airway evaluation, however published information is lacking regarding CT tracheal dimensions in English Bulldogs. Objectives of this prospective cross-sectional study were to describe radiographic and CT tracheal dimensions in a sample of clinically normal English Bulldogs and compare these values with tracheoscopy scores...

Positron emission tomography (PET) using the radiopharmaceutical tracer fluorine-18 fluorocholine (FCh) can elucidate tumors based on differences in choline phospholipid metabolism between tumor and surrounding tissue. The feasibility of detecting hepatocellular carcinoma (HCC) using FCh PET has been shown despite constitutively high parenchymal choline metabolism in the liver. Since HCC frequently develops in the setting of chronic liver disease, we comparatively evaluated FCh PET/CT between cirrhotic and non-cirrhotic patients with HCC to investigate the effects of hepatic dysfunction on tumor detection and the tumor-to-background ratio (TBR) of FCh uptake...

BACKGROUND: Hitting a dental root during the insertion of orthodontic mini-implants (OMIs) is a common adverse effect of this intervention. This condition can permanently damage these structures and can cause implant instability. Increased torque levels (index test) recorded during the insertion of OMIs may provide a more accurate and immediate diagnosis of implant-root contact (target condition) than radiographic imaging (reference standard). An accurate index test could reduce or eliminate X-ray exposure...

In much of medical oncology, including neuro-oncology, there is great interest to evaluate the therapeutic potential of immune-based therapies including vaccines, adoptive T cell strategies and modulators of immune checkpoint regulators such as cytotoxic T lymphocyte antigen 4 and programmed death 1. Immune-based treatments exert an indirect anti-tumor effect by generating potent, tumor-targeting immune responses. Robust anti-tumor immune responses have been shown to achieve encouraging radiographic responses across the spectrum of applied immunotherapeutics which are felt to be indicative of a bona fide anti-tumor effect...

OBJECTIVE: To investigate clinical and radiological features of Tolosa-Hunt syndrome (THS) and examine their diagnostic value, and to propose clinical and radiological features that indicate other symptomatic painful ophthalmoplegias (SPOs) in order to distinguish them from THS. BACKGROUND: Clinical presentations of THS are nonspecific and may overlap with many etiologies. Therefore, excluding other SPOs is essential for correct diagnosis. At the present time, the predictive value of the current International Classification of Headache Disorders (ICHD) criteria is not well established, and specific imaging markers that can discriminate SPOs from THS are lacking...
