Developing an enterprise approach to imaging technology rather than a radiology focus has recently increased. The communicator needs to be aware of this shift.The Middle East countries participated in the survey have confirmed the following major benefits of Medical Image Exchange:
  • ✔Fast access to both image and report
  • ✔Enable tele-services for second opinion, consulting and reporting
  • ✔Improve patient journey, workflow and diagnosis
  • ✔Allowed more patient engagement to be in place
The Middle East countries that participated in this survey have agreed on the following shared challenges regarding Medical Imaging Exchange:
  • ✔Lack of enterprise imaging governance at the early stage of implementation. It will organize the who, when, and how. In addition, any fees and or payment involved for physicians
  • ✔Infrastructure availability to handle such large volume of data. Growing from mega-byte to petabyte per year is challenge for infrastructure. Cloud against On Premises-Installation implementation model
  • ✔Interoperability and integration to connect multi specialties from different systems. In addition, how far existing systems are ready for that. A standard-based framework is mature for image exchange, but what follows for other domains? There is a need to move beyond radiology images so as to include images from pathology, ophthalmology, and dermatology
There are other countries in the region requiring guidance, support, and funding to move forward from the compact disc into internet-based interoperable image exchange. This should be considered part of the World Health Organization and the United Nation development to the region in the healthcare sector.  相似文献

This article focuses on what Luis von Ahn called the “twofer,” that is, a single solution that elegantly addresses two problems on a large scale. We describe two of von Ahn’s creations: reCAPTCHA, which validates a human web presence while also digitizing hard-to-read words, and Duolingo, which teaches new languages while translating the web. We then consider how this approach can be applied to medical education. Embedding Wikipedia-editing into educational settings is one such solution that could both improve the quality of health information available to the public while enhancing the learning of future health professionals.  相似文献

We aimed to conduct the current meta-analysis to provide better insight into the efficacy of mechanical thrombectomy (MT) in managing COVID-19 patients suffering from a stroke. An electronic search was conducted through eight databases for collecting the current evidence about the efficacy of MT in stroke patients with COVID-19 until 18 December 2021. The results were reported as the pooled prevalence rates and the odds ratios (ORs), with their corresponding 95% confidence intervals (CI). Out of 648 records, we included nine studies. The prevalence of stroke patients with COVID-19 who received MT treatment was with TICI ≥2b 79% (95%CI: 73–85), symptomatic intracranial haemorrhage 6% (95%CI: 3–11), parenchymal haematoma type 1, 11.1% (95%CI: 5–23), and mortality 29% (95%CI: 24–35). On further comparison of MT procedure between stroke patients with COVID 19 to those without COVID-19, we found no significant difference in terms of TICI ≥2b score (OR: 0.85; 95%CI: 0.03–23; p = 0.9). However, we found that stroke patients with COVID-19 had a significantly higher mortality rate than stroke patients without COVID-19 after MT procedure (OR: 2.99; 95%CI: 2.01–4.45; p < 0.001). Stroke patients with COVID-19 can be safely and effectively treated with MT, with comparable reperfusion and complication rates to those without the disease.  相似文献

Case in the paper is of a 24-year-old woman presenting to Baqiyatallah hospital, Tehran, Iran with the occasional fever, weakness, myalgia, fatigue, body aches, and headache who was diagnosed with Coronavirus disease-19 (COVID-19) PCR test. Chest computed tomography (CT) showed spontaneous pneumomediastinum (SPM) and pneumopericardium (SPP). Here, we described SPM, and SPP in a patient with COVID-19, presenting a severe course of the disease.  相似文献
