Philip Benjamin, Faraan Khan, Andrew D MacKinnon
Diffusion weighted imaging (DWI) has transformed the radiological assessment of a variety of cerebral pathologies, in particular acute stroke. In neuroimaging studies, DWI can also be used to evaluate pathology outside the brain parenchyma, although it is sometimes underutilised for this purpose. In this pictorial review, the principles of diffusion-weighted imaging are outlined and thirteen cases of abnormal diffusion outside the brain parenchyma are illustrated in order to show DWI as a useful sequence for the evaluation of the following recommended review areas: the dural venous sinuses, internal carotid arteries, meninges, ventricles, cavernous sinus and orbits, skull base, and lymph nodes...

OBJECTIVES: Pancreatic cancer is a difficult-to-treat disease with a persistently high mortality rate. We evaluated dose distribution simulation with respiratory-gated carbon-ion pencil beam scanning (C-PBS) with a simultaneous integrated boost (SIB) to increase tumor dose, sparing organs at risk (OARs). METHODS: Using four-dimensional computed tomography (4DCT) data of 12 patients, we delineated gross tumor volume (GTV) and two clinical target volumes (CTVs). To consider beam range intrafractional uncertainty, we calculated field-specific target volumes (FTVs), from which two planning target volumes (PTVs) were generated...

Adrenal incidentalomas are unsuspected, asymptomatic adrenal masses detected on imaging. Most are non-functioning benign adrenocortical adenomas, but can represent other benign lesions or lesions requiring therapeutic intervention including adrenocortical carcinoma, pheochromocytoma, hormone-producing adenoma or metastasis. This review summarises and highlights radiological recommendations within the recently issued guidelines for the management of adrenal incidentalomas from European Society of Endocrinology Clinical Practice in collaboration with European Network for Study of Adrenal Tumours...

Albert C Chen, Mark D Bonnen, Henry Mok
OBJECTIVE: Metastatic spinal cord compression (MSCC) is an oncologic emergency that often warrants emergent treatment, but it is unclear if radiation treatment can be optimally managed from an offsite radiotherapy facility. METHODS: Patient charts from consecutive MSCC patients that were treated with radiotherapy alone either at an onsite hospital radiation department (from 2008 to 2012) or an offsite radiotherapy center (2012-2015) were reviewed. Patients' clinical parameters were compared across groups with either the Chi-squared test or Fisher's exact test, while survival curves were compared with the log-rank test...

We aim to review the challenges and opportunities that radiology may face once the United Kingdom (UK) leaves the European Union (EU). Even before the exit negotiations commence, uncertainty over future policies and funding within the UK may influence the National Health Service (NHS). We discuss the potential impact that financial, regulatory and social change may have on healthcare, and radiology in particular. Current difficulties in recruitment and retention of radiologists and the challenges that Brexit presents are considered...

Fionn Williams, Paul David Griffiths
OBJECTIVE: Lissencephaly is a rare disorder of cortical developmental, which usually carries increased risk of recurrence in future pregnancies. In this prospective observational study we wish to test the hypothesis that sulcation patterns can be used to diagnose lissencephaly successfully on in utero MR (iuMR) imaging in the third trimester but not in the late second trimester foetus. METHODS: Pregnant women were recruited into this study if they had an increased risk of foetal lissencephaly based on a foetus or child with lissencephaly in an earlier pregnancy...

OBJECTIVES: Blurred images in Full Field Digital Mammography (FFDM) are a problem in the UK Breast Screening Programme. Technical recalls may be due to blurring not being seen on lower resolution monitors used for review. This study assesses the visual detection of blurring on a 2.3 megapixel (MP) monitor and a 5 MP report grade monitor and proposes an observer standard for the visual detection of blurring on a 5 MP reporting grade monitor. METHOD: Twenty-eight observers assessed 120 images for blurring; 20 had no blurring present whilst 100 had blurring imposed through mathematical simulation at 0...
