A Diagnostic Dilemma of Prevertebral Abscess Versus Food Bolus on Lateral Neck X-Ray: A Case Report.

In this case, a 76-year-old female presenting with globus sensation post-oral intake demonstrated radiographical evidence of mottled radiolucency and prevertebral widening on a lateral neck X-ray at the inferior C4/cricoid cartilage, leading to concern for a prevertebral abscess. A decision was made to proceed with an urgent gastrointestinal endoscopy, and a food bolus was identified and removed, leading to a full remission of the patients' symptoms. In this case, an appropriate diagnosis was achieved by combining multiple investigations, which highlights to clinicians that taking investigations in isolation, with the aforementioned lateral neck X-ray being the primary example, could lead to potential misdiagnosis and mismanagement of patients.

Incidental Pulmonary Nodules Are Common on CT Coronary Angiogram and Have a Significant Cost Impact.

Background: Computed tomography (CT) coronary angiogram (CTCA) is commonly used for diagnostic evaluation of low-moderate risk patients due to its excellent performance and cost-effectiveness. However, previous cost analyses have not factored in the burden of management of pulmonary nodules, which are a common occurrence. We sought to describe the frequency and characteristics of lung nodules on CTCA in an Australian tertiary hospital, and to assess cost impacts.

Collaborative model for training and credentialing point-of-care ultrasound: 6-year experience and quality outcomes.

Introduction: Point-of-care ultrasound (PoCUS) is a rapidly growing area, providing physicians with a valuable diagnostic tool for patient assessment. This paper describes a collaborative model, utilising radiology department ultrasound expertise, to train and credential physicians in PoCUS. A 6-year experience of the implementation and outcomes of the programme established within the emergency departments of a large, multi-campus hospital network are presented.

Achieving adequate margins in ameloblastoma resection: the role for intra-operative specimen imaging. Clinical report and systematic review.

Background: Ameloblastoma is a locally aggressive odontogenic neoplasm. With local recurrence rates reaching 90%, only completeness of excision can facilitate cure. Surgical clearance has widely been based on pre-operative imaging to guide operative excision margins, however use of intra-operative specimen x-ray or frozen-section has been sought to improve clearance rates, and advanced imaging technologies in this role have been proposed.

Measurement of the lateral ventricles in the neonatal head: comparison of 2-D and 3-D techniques.

Neonatal cranial ultrasound is routinely performed to screen preterm infants for complications of prematurity. A key component of this examination is the measurement of the lateral ventricles to identify and monitor ventriculomegaly. This study assesses the two-dimensional (2-D) interobserver error of neonatal cranial lateral ventricle measurements on 40 neonates who were undergoing cranial ultrasound in the neonatal intensive care unit.
