Cardiac computed tomography angiography (CCTA) is a commonly used diagnostic imaging tool for cardiovascular disease. Despite constant improvements to imaging technologies, the radiation dose to patients remains a concern when using this procedure. Diagnostic reference levels (DRLs) are used as a trigger to identify and alert individual facilities that are using high doses during CT. This study aims to assess patient radiation dose and establish new national DRLs (NDRL) associated with CCTA in Saudi clinical practices...

BACKGROUND: The incidence of periprosthetic fractures associated with total knee arthroplasty (PpFxK) has been reported to be 0.3 - 5.5%. 40% of all cases are related to revision TKA. The most common localisation is the distal femur. Classification is performed according to Rorabeck (RB). RB I - II fractures are usually treated with locked plating and retrograde intramedullary nailing, whereas RB III fractures are an indication for revision arthroplasty using a hinged endoprosthesis...

AIMS: Growth of the cancer incidence rate in Iran has been very high in recent years. Therefore, the Iranian health care system should be prepared for the treatment of a huge number of patients in the foreseeable future. One of the most important treatment options for cancer is radiation. However, there is no comprehensive information on infrastructure for radiation oncology in this country. MATERIALS AND METHODS: In 2015, a questionnaire was designed by the Iranian Society of Clinical Oncology (ISCO) and all radiation oncology centres in the country were visited to determine four important components of radiation oncology services, including facilities, equipment, personnel and patients...

RATIONALE: Presurgical localization of the epileptogenic focus is critical to successful surgery. Traditionally, localization of the epileptogenic focus depends on seizure semiology, scalp video-electroencephalography (vEEG), magnetic resonance imaging (MRI), neuropsychological assessment, and, when needed, intracranial EEG (iEEG). We aimed to explore the role of positron emission tomography (PET) in the presurgical evaluation of patients with refractory epilepsy. METHODS: A retrospective review was conducted on patients from London Health Sciences Centre (London, Ontario) with refractory epilepsy who underwent PET from September of 2011 to April of 2016...

OBJECTIVE: Current standard diagnostic practice of bacterial infections by visual inspection under white light is subjective, and microbiological sampling is suboptimal due to high false negative rates and the lengthy time needed for culture results to arrive. The MolecuLight i:X Imaging Device attempts to combat the issues faced in standard practice by providing a non-contact, real-time method of visualising bacteria within wounds. Our aim was to test this imaging device in a series of patients...

OBJECTIVE: At our tertiary cardiothoracic centre cardiac MRI and thoracic CT scans are performed in patients with implanted LINQ devices. The degree of foreign body artefact associated with the LINQ device, and its clinical importance, has not previously been assessed. A case series review was therefore performed with a simultaneous review of patient safety and data loss events, secondary to the MRI environment. METHODS: A local database search identified LINQ device patients who underwent thoracic CT or cardiac MRI scans between March 2014 and December 2016...

PURPOSE: Superimposed three-dimensional (3D)-models obtained from CT-images have been used to evaluate displacement of femoral neck fractures, but this method assumes symmetrical anatomy of normal femurs. The present study aimed to compare the spatial orientation of the left and right proximal femur, thus establishing if 3D models can be used as a reference standard for the evaluation of fracture displacement. METHODS: We generated 3D-CT-models of 20 patients with no skeletal pathology of the proximal femurs...

Background: Currently, a PET-CT is used to assess the need for extended field radiotherapy of para-aortic lymph nodes (PALN) in International Federation of Gynaecology and Obstetrics (FIGO) stage IB2, IIA2-IVA (locally advanced stage) cervical cancer. A small study established a sensitivity and specificity estimate for PALN metastases of 50% (95% CI; 7-93%) and 83% (95% CI; 52-98%), respectively. Surgical staging of PALN may lead to a higher diagnostic accuracy. However, surgical staging of para-aortic lymph nodes in locally advanced stage cervical cancer is not common practice...

OBJECTIVE: Rural emergency departments (EDs) are an important gateway to care for the 20% of Canadians who reside in rural areas. Less than 15% of Canadian rural EDs have access to a computed tomography (CT) scanner. We hypothesized that a significant proportion of inter-facility transfers from rural hospitals without CT scanners are for CT imaging. Our objective was to assess inter-facility transfers for CT imaging in a rural ED without a CT scanner. RESULTS: We selected a rural ED that offers 24/7 medical care with admission beds but no CT scanner...
