Both of these factors have contributed to the stagnant state of radiology in Mexico.Conclusion: There are many factors contributing to the state of radiology in Mexico, including a high poverty percentage and low expenditure on healthcare. It is important to increase the number of medical imaging units throughout the country and replace the current aging scanners to help all patients.","PeriodicalId":92855,"journal":{"name":"The journal of global radiology","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49646309","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Materials and Methods: In this retrospective study, we included 130 patients (mean 59 +/-17 years, range 20-91, F:M 74:56) who underwent abdominal/pelvic CT examinations between April 1st-12th, 2019. CT examinations were prospectively encountered in clinical work at the Centre Hospitalier Universitaire de Kigali or University Teaching Hospital of Kigali (CHUK) in Kigali, Rwanda, where the radiology report impression, patient age, gender, study indication, CT protocol, and clinical diagnosis were recorded when available. Abdominal/pelvic CT examinations at the Massachusetts General Hospital (MGH) in Boston, Massachusetts, United States were then retrospectively reviewed for the same information. Patient age and gender were compared using Student’s t-test and Chi-square statistic. Frequency of formal recommendations in radiology reports, available comparison of CT examinations, presence of known diagnoses, and intravenous and oral contrast media use were compared using Fisher’s exact test. Diagnostic categories were qualitatively compared. Results: A wide variety of pathology was encountered by abdominal/pelvic CT at both sites of imaging, with qualitative differences observed in cancer types, infectious agents, and how imaging guides care. Patients in Rwanda were older (p=0.0017), more likely to receive intravenous (p < 0.05) and positive oral contrast (p < 0.05) media and less likely to receive a formal recommendation in their radiology report (p < 0.05). Patients in the United States were more likely to have an available prior abdominal/pelvic CT (p < 0.05), to present for follow-up of a known diagnosis (p < 0.05), and to receive a formal recommendation in their radiology report (p < 0.05). Conclusion: Participation in global radiology collaborations is beneficial for radiologists by broadening exposure to pathologies and practice different from their own institution and region.","PeriodicalId":92855,"journal":{"name":"The journal of global radiology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45602425","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Establishing radiology services is increasingly recognized as a priority in resource-limited settings. Myanmar has a tremendous disease burden that is treatable with interventional radiology (IR) techniques, and aims to grow and effectively integrate this service into its public healthcare sector. Through collaborations between Asia Pacific Society of Cardiovascular and Interventional Radiology (APSCVIR) and Myanmar Radiological Society (MRS), the field of IR has grown exponentially over recent years. This study aims to provide a Myanmar national IR report on the current trends and future challenges. Methods and materials: Descriptive variables across five domains (facility and equipment, workforce, supplies, infrastructure, and casemix) from the four public sector hospitals with IR capability were obtained between 2016-2019. The four hospitals were Yangon General Hospital (YGH), Yangon Specialty Hospital (YSH), Mandalay General Hospital (MGH), and Defense Services General Hospital (DSGH). Data were analyzed to demonstrate progress in IR and the differing casemix. Results: There are currently four IR-capable hospitals and nine interventional radiologists across Myanmar’s public healthcare sector. IR case volumes tripled from 514 cases in 2016 to more than 1,500 cases in 2019. The three most common procedures performed were trans-arterial chemoembolization (TACE, 63%), bronchial arterial embolization (BAE, 7.7%), and drainages (7.7%). Significant challenges to the growth and adoption of IR services span the domains of infrastructure, equipment and supplies, workforce, and IR awareness, among other clinical specialties. Conclusion: Myanmar’s healthcare priorities, coupled with international radiological outreach programs, have led to rapid growth of IR. The exponential growth in case volumes is promising for Myanmar and other developing countries. But to widen the scope of practice and integrate the service within local clinical workflows, a holistic effort that addresses multiple domains is needed in the future.","PeriodicalId":92855,"journal":{"name":"The journal of global radiology","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71256185","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This has become especially apparent in the field of medicine and diagnostic imaging with modalities such as ultrasound (US), computed tomography (CT), magnetic resonance imaging (MRI) and nuclear molecular imaging becoming rather routine in the diagnostic armamentarium. While considered routine and accessible in developed nations, unfortunately for the greater part of the world’s population, these incredible technological break-throughs have virtually no meaning. For approximately 3.6 billion people, or about 60% of the world’s population, there is little or not access to the simplest examination such as a chest or extremity radiograph (2). For example, if x-ray capability is available in Guatemala City, patients may have to travel for several days by foot to reach the city where the machine is located. Once they reach the site, lines and wait times may be long, causing significant delay in diagnosis and treatment. This delay in diagnosis and treatment has effects at the individual level with increase in morbidity and mortality, but also at the public health level, as seen with pulmonary tuberculosis, a disease that causes approximately 1.6 million deaths a year throughout the world and about 400,000 in India alone (7). Additionally, tuberculosis has become a very important complication for AIDS patients around the world.","PeriodicalId":92855,"journal":{"name":"The journal of global radiology","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42072293","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Digital technology has gone worldwide: radiologists in all countries reported that digital radiography was either equally or more available than analog technologies. Sixty percent of radiologists said that they were “always” or “often” involved in the purchasing decisions in their institutions, but only 35% reported that they had the final say. According to the radiologists surveyed, the era of donated equipment is ending. Ninety-five percent felt that the disadvantages of donated equipment outweighed the cost savings. Training was a key concern both for radiologists and vendors. Radiologists felt that training was insufficient, materials left behind too complicated, online materials too limited, and follow-up from vendors insufficient.
