PURPOSE: Radiation oncologists are responsible for deciding which day-to-day variations are acceptable or not in the treatment setup. However, properly qualified and trained radiation therapists might be capable to perform image registration. We evaluated in our centre the capability and accuracy of radiation therapists to validate positioning images in a prospective study. METHODS AND PATIENTS: A total of 84 patients treated for prostate, head and neck, lung or breast cancer was prospectively and randomly included from July 2011 to July 2013 in radiotherapy unit of our institution...

BACKGROUND AND PURPOSE: It is assumed that up to 30 % of clinically diagnosed acute ischaemic strokes (AIS) are actually stroke mimics (SM). Our aim was to evaluate the usefulness of advanced CT including CT angiography (CTA) and CT perfusion (CTP) findings when distinguishing AIS from seizure-related SM. METHODS: Over a 22-month period data were gathered of patients who presented to our stroke centre with AIS-like symptoms and were examined immediately with an advanced CT, analysed and evaluated by two experienced neuroradiologists who preferred SM rather than AIS...

BACKGROUND: The subtype of basal cell carcinoma (BCC) influences the choice of treatment. Optical coherence tomography (OCT) is a non-invasive imaging tool and recent development of angiographic version of OCT has extended the application of OCT to image the cutaneous microvasculature (so called dynamic OCT, D-OCT). This study explores D-OCT's ability to differentiate the common BCC subtypes by microvascular and structural imaging. METHODS: 81 patients with 98 BCC lesions, consisting of three subtypes: 27 superficial BCC (sBCC), 55 nodular BCC (nBCC) and 16 infiltrative BCC (iBCC), were D-OCT scanned at three European dermatology centres...

The relatively low incidence and often atypical clinical presentation of soft-tissue sarcomas (STS) impedes early and adequate diagnosis. Patients may report on recently enlarged soft-tissue swellings, infrequently complain of painful lesions, or even have no symptoms at all.A thorough diagnostic work-up is essential in order to distinguish between benign soft-tissue tumours and STSs. Patient history, clinical features and radiological findings all help in assessing the underlying pathology. 'Worrying' features such as recent increase in size, deep location relative to the fascia, a tumour exceeding 4 cm in size, and invasive growth patterns seen on imaging should prompt verification by biopsy...

Xanthogranulomatous cholecystitis (XGC) is an uncommon variant of chronic cholecystitis, characterized by focal or diffuse destructive inflammatory process. The importance of XGC is that it mimics gallbladder carcinoma (GBC) both preoperatively and intra-operatively, since it can present with pericholecystic infiltration, hepatic involvement and lymphadenopathy. As a result of this misdiagnosis which is not infrequent, the patient may need to undergo an unnecessary radical cholecystectomy rather than only a cholecystectomy which is associated with greater morbidity and mortality...

Objective: Vesicouterine fistula (VUF) is an uncommon cause of female genito-urinary fistula. Most of these fistulas are due to lower segment uterine cesarean section (LSCS). Traditionally, open surgical repair has been the traditional treatment. However, laparoscopic repair of VUF is a minimally invasive technique and few case reports have been published with short term follow up. In the present study, we are presenting our long- term outcome of laparoscopic repair of VUF. Material and methods: A retrospective analysis of 8 patients with VUF was performed from 2010 to 2015...

BACKGROUND: The Xpert MTB/RIF assay is an automated molecular test that has improved the detection of tuberculosis and rifampicin resistance, but its sensitivity is inadequate in patients with paucibacillary disease or HIV. Xpert MTB/RIF Ultra (Xpert Ultra) was developed to overcome this limitation. We compared the diagnostic performance of Xpert Ultra with that of Xpert for detection of tuberculosis and rifampicin resistance. METHODS: In this prospective, multicentre, diagnostic accuracy study, we recruited adults with pulmonary tuberculosis symptoms presenting at primary health-care centres and hospitals in eight countries (South Africa, Uganda, Kenya, India, China, Georgia, Belarus, and Brazil)...

OBJECTIVE: This guideline presents an evidence-based technical update and recommendations for the performance of early comprehensive fetal anatomic scanning (ECFAS) at 11 to 16 weeks' gestation. OPTIONS: Patients at high risk for fetal anomalies and in whom traditional mid-second trimester transabdominal imaging may be challenging or who may benefit from earlier identification of fetal anomalies may be suitable for early fetal anatomy scanning. OUTCOMES: This practice may result in earlier identification of fetal anomalies and provide earlier intervention options in high-risk populations and/or in populations where mid-second trimester transabdominal scanning is challenging...

INTRODUCTION: Pseudoprogression (psPD) is a transient post-treatment imaging change that is commonly seen when treating glioma with chemotherapy and radiation. The use of apparent transverse relaxation rate (R2∗), which is calculated from a contrast-free multi-echo gradient echo Magnetic Resonance Imaging (MRI) sequence, may allow for quantitative identification of patients with suspected psPD. METHODS: We acquired a multi-echo gradient echo sequence using a 3T-Siemens Prisma MRI...

PURPOSE: We aimed to investigate changes in retinal vascular geometry over time after panretinal photocoagulation (PRP) in patients with proliferative diabetic retinopathy (PDR). METHODS: Thirty-seven eyes with PDR were included. Wide-field fluorescein angiography (Optomap, Optos PLC., Dunfermline, Scotland, UK) was used to diagnose PDR at baseline and to assess activity at follow-up month three and six. At each time-point, a trained grader measured retinal vessel geometry on optic disc (OD) centred images using semiautomated software (SIVA, Singapore I Vessel Assessment, National University of Singapore, Singapore) according to a standardized protocol...

BACKGROUND: Ethmoidal dural arterio-venous fistulas (DAVFs) are rare and aggressive lesions, usually treated by microsurgical disconnection of the fistula. Transarterial embolization is rarely performed because of the risk of retinal ischemia. Transvenous embolization has been reported as an alternative approach. We describe our experience in transvenous embolization of ethmoidal DAVFs and review the literature focusing on technical and safety aspects of the procedure. METHODS: We retrospectively identified 4 patients with ethmoidal DAVFs treated by transvenous embolization in a single centre...

Paediatric fractures of the tibial spine are relatively rare and controversy remains around how these injuries are best managed (Gans et al., 2014; Hargrove et al., 2004). Consequently most non-specialised paediatric units have limited experience of managing these injuries. This study aims to review the management and outcomes of isolated paediatric tibial spine fractures in a tertiary paediatric orthopaedic centre between 2008 and 2016. Data were collected on patient demographics, mechanism of injury, imaging, Meyers and McKeever grade of injury (Meyers and McKeever), management and outcomes, including Cincinnati and Lysholm-Tegner knee scores at a mean of 36 months post-operatively...

AIM: 18 F FDG-PETCT derived markers of tumour metabolism have been reported to have prognostic significance in a variety of tumours. Host inflammation is also recognised to have prognostic significance. The aim of the present study was to investigate the relationship between these markers and host systemic inflammation in patients undergoing elective surgery for colorectal cancer. METHODS: Patients with histologically confirmed colorectal cancer, who underwent elective surgery between 2008 and 2015, who also underwent 18 F FDG-PETCT, at a single centre were included (n =103)...
