Clinical value of whole-body F-18 fluorodeoxyglucose positron emission tomography/computed tomography in patients with carcinoma of unknown primary.
The purpose of the study is to investigate the clinical value of F-18 fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT) in detecting the primary sites in patients with carcinoma of unknown primary (CUP). ⋯ FDG PET/CT whole-body imaging is a valuable tool in detecting the primary tumour of patients with CUP site.

Multicenter StudyAdherence to MRI protocol consensus guidelines in multiple sclerosis: an Australian multi-centre study.
Multiple sclerosis (MS) is a debilitating disease that causes significant morbidity within a young demographic. Diagnostic guidelines for MS have evolved, and imaging has played an increasingly important role in diagnosis over the last two decades. For imaging to contribute to diagnosis in a meaningful way, it must be reproducible. Consensus guidelines for MRI in MS exist to define correct sequence type and imaging technique, but it is not clear to what extent they are followed. This study reviewed MRI studies performed on Australian individuals presenting with a first clinical diagnosis of central nervous system demyelination (FCD) for adherence to published guidelines and discussed practical implementation of MS guidelines in light of recent updates. ⋯ Only a small number of MRI investigations performed included all of the sequences stipulated by consensus guidelines. This is likely due to poor awareness in the imaging community of the guidelines and the rationale behind certain sequences. Radiologists with a sub-speciality interest in neuroradiology should take ownership of this issue and ensure that recommended imaging guidelines are followed.

Adherence to Canadian C-Spine Rule in a regional hospital: a retrospective study of 406 cases.
Cervical spine radiography may be over-utilised in an emergency department setting. The Canadian C-Spine Rule has been developed to reduce unnecessary radiography. Our aim was to retrospectively determine the proportion of cervical spine radiographs requested through the emergency department for trauma patients that were clinically indicated, according to the Canadian C-Spine Rule. ⋯ Applying the Canadian C-Spine Rule would have safely reduced the incidence of cervical spine radiography by 38%. This would also reduce costs, patient morbidity and radiation exposure.

CT-only planning for Gamma Knife radiosurgery in the treatment of trigeminal neuralgia: methodology and outcomes from a single institution.
Gamma Knife radiosurgery (GKRS) has been established as a safe and effective treatment option for trigeminal neuralgia. Some patients have contraindications to magnetic resonance imaging (MRI), the standard stereotactic imaging used for GKRS treatment planning. Computerized tomography (CT) imaging may be used as an alternative in this scenario. We sought to evaluate the outcomes of our patients treated using this technique. ⋯ Stereotactic CT-only treatment planning of GKRS for the treatment of trigeminal neuralgia is feasible and safe. Further studies are necessary to determine if the long-term durability of pain relief is comparable to that of MRI-based GKRS planning.

Case ReportsPartial anomalous pulmonary venous return in patients with pulmonary hypertension.
Anomalous pulmonary venous return is an uncommon congenital malformation, and may be partial or total. Partial anomalous pulmonary venous return (PAPVR) is more common than total anomalous pulmonary venous return, and is often associated with other congenital cardiac anomalies. ⋯ We report two cases of PAPVR detected on Computed Tomography Pulmonary Angiogram (CTPA) for the work up of pulmonary hypertension. The cases demonstrate that, although uncommon, partial anomalous pulmonary venous return can be a contributing factor to pulmonary hypertension and pulmonary veins should be carefully examined when reading a CTPA study.
