Pancreaticoduodenectomy is a complex, high-risk surgical procedure performed for tumours of the pancreatic head and other periampullary structures. The rate of perioperative mortality has decreased in the past number of years but perioperative morbidity remains high. This pictorial review illustrates expected findings in early and late post-operative(More)
Cystic fibrosis (CF) is the most common lethal autosomal recessive disease in the white population. Mutation of the CF transmembrane conductance regulator gene on chromosome 7 results in production of abnormally viscous mucus and secretions in the lungs of patients with CF. A similar pathologic process occurs in the gastrointestinal tract, pancreas, and(More)
In order to reduce HIV transmission, improved understanding of factors that motivate safer sexual behaviour is needed. The Health Belief Model attempts to explain health-related behaviour, including HIV-preventive behaviour. The association of six elements of this model--AIDS knowledge, perceived susceptibility to HIV infection, perceived effectiveness of(More)
AIM To assess if diffusion-weighted imaging (DWI) alone could be used for follow-up of neuroendocrine hepatic metastases. MATERIAL AND METHODS This was a retrospective study, approved by the institutional review board. Twenty-two patients with neuroendocrine liver metastases who had undergone more than one liver magnetic resonance imaging (MRI)(More)
OBJECTIVES Prostate cancer staging MR examinations commonly include abdominal sequences to assess for non-regional (common iliac or para-aortic) nodal metastasis. In our experience the diagnostic yield of this is limited, but incidental findings are frequent, often necessitating further investigations. The aim of this study is to assess the diagnostic(More)
RATIONALE AND OBJECTIVES The purpose of this study was to critically appraise and compare the diagnostic performance of imaging modalities that are used for the diagnosis of intussusception and methods used in the treatment of ileocolic intussusception. METHODS A focused clinical question was constructed and the literature was searched using the patient,(More)
More data are needed regarding the radiology, co-morbidities and natural history of smoking-related interstitial fibrosis (SRIF), a common pathological finding, mainly described heretofore in association with lung cancer, where respiratory bronchiolitis (RB) usually co-exists. We prospectively acquired high resolution CT scan data (edge-enhancing lung(More)
There has been an increase in gun-related crime in Ireland over the last decade to gangland violence, especially in west Dublin. This places a burden on hospital services not previously encountered. The aim of this study was to examine the demographics of gunshot: injuries presenting to a Dublin teaching hospital, and the impact on radiology over a ten year(More)
PURPOSE We aimed to prospectively evaluate anatomic chest computed tomography (CT) with tissue characterization late gadolinium-enhanced magnetic resonance imaging (MRI) in the evaluation of pulmonary fibrosis (PF). METHODS Twenty patients with idiopathic pulmonary fibrosis (IPF) and twelve control patients underwent late-enhanced MRI and high-resolution(More)
