No formal audit has been performed on BCT at our institution.Objectives: To determine the incidence and risk factors for ipsilateral breast tumour recurrence (IBTR). Study the imaging features of IBTR. Determine adherence to the proposed annual mammographic surveillance schedule.Method: Clinical, radiological and histopathological records of patients who underwent BCT from 01 January 2011 to 31 December 2015 were reviewed. Patients were followed up for at least 5 years.Results: Ninety-two patients were included in the study with a mean age of 54.3 years. Eighty of the 92 (87.0%) patients were imaged within 1-year post-BCT. Ipsilateral breast tumour recurrence was 6/92 (6.5%) with mean time to IBTR of 34.4 months. One of the 92 (1.0%) patients had a contralateral metachronous recurrence with no IBTR and 11/92 (12.0%) had distant metastases only. Pathological tumour size and extent (pT2) (68.5%) and pathological lymph node (pN0) (65.2%) were the most common locoregional staging. Infiltrating ductal carcinoma was the most common histological type (88%). Age < 35 years was associated with breast cancer recurrence (p < 0.01). Imaging findings of recurrence were microcalcification (odds ratio [OR]: 4), asymmetric density (OR: 4) and skin thickening (OR: 2.5).Conclusion: The occurrence of IBTR following BCT in our unit is acceptable and comparable to local and international units. The accuracy of assessing the post-BCT breast for IBTR is in keeping with international standards.Contribution: Improved radiological imaging interpretation of the post-BCT breast.","PeriodicalId":43442,"journal":{"name":"SA Journal of Radiology","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2023-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10157414/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9485177","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fifty-seven cases with 57 initial and 107 follow-up radiographs were included. Each follow-up radiograph was analysed for changes in borders, locularity, effects on surrounding structures and lesion size.Results: There was a general increase in poorly-demarcated lesions, with seven cases transforming from an initial unilocular to a multilocular appearance. At follow-up, there was an increase in cortical thinning and cortical destruction. Ameloblastomas presented with a three-fold increase in average size from the initial to follow-up visits. Regression analysis showed a statistically significant relationship between lesion duration and length (p = 0.001). A statistically significant relationship existed between duration and overall lesion dimensions when only the first and last observations per patient were used (p = 0.044).Conclusion: Considering the aggressive nature and unlimited growth potential, ABs with delayed treatment may show extensive growth, complicating their eventual management.Contribution: This study aimed to raise awareness of the importance of the timeous management of patients with AB by highlighting the detrimental effects of delayed treatment.","PeriodicalId":43442,"journal":{"name":"SA Journal of Radiology","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10244951/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9612957","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Verification of catheter position by chest X-ray (CXR) is usually performed postoperatively.Objectives: This prospective observational study assessed the diagnostic accuracy of peri-operative ultrasound and a 'bubble test' to detect malposition and pneumothorax.Method: Sixty-one patients undergoing peri-operative CVC placement were included. An ultrasound protocol was used to directly visualise the CVC, perform the 'bubble test' and assess for the presence of pneumothorax. The time from agitated saline injection to visualisation of microbubbles in the right atrium was evaluated to determine the correct position of the CVC. The time required to perform the ultrasound assessment was compared to that of conducting the CXR.Results: Chest X-ray identified 12 (19.7%) malpositions while ultrasound identified 8 (13.1%). Ultrasound showed a sensitivity of 0.85 (95% confidence interval [CI]: 0.72 to 0.93) and a specificity of 0.5 (95% CI: 0.16 to 0.84). The positive and negative predictive values were 0.92 (95% CI: 0.80 to 0.98) and 0.33 (95% CI: 0.10 to 0.65), respectively. No pneumothorax was identified on ultrasound and CXR. The median time for ultrasound assessment was significantly shorter at 4 min (interquartile range [IQR]: 3-6 min), compared to performing a CXR that required a median time of 29 min (IQR: 18-56 min) (p < 0.0001).Conclusion: This study showed that ultrasound produced a high sensitivity and moderate specificity in detecting CVC malposition.Contribution: Ultrasound can improve efficiency when used as a rapid bedside screening test to detect CVC malposition.","PeriodicalId":43442,"journal":{"name":"SA Journal of Radiology","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10319935/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9807399","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The onset of the coronavirus disease 2019 (COVID-19) pandemic catapulted South African healthcare into the arena of teleradiology. This created the environment for re-examining the factors that enable or inhibit the uptake of teleradiology in both the public and private sectors.Objectives: This article reports on a study of a select sample of private and public sector radiologists' experiences with, and perceptions of, the benefits, opportunities, challenges and barriers to the implementation of teleradiology in the South African context.Method: Qualitative data on the perceived benefits and challenges of teleradiology, as well as on its enablers and the barriers to its implementation, were collected and analysed.Results: The uptake of teleradiology in the sample increased by 15.9% during the COVID-19 pandemic. The results demonstrated that teleradiology was perceived to have clear benefits on operational, personal and societal levels.Conclusion: It is important to address structural barriers to the implementation of teleradiology. Clear communication strategies and multistakeholder engagement are also required.Contribution: By investigating radiologists' experience with teleradiology, this study provides an understanding of the benefits, opportunities, challenges and barriers to implementation of services. These insights enable informed decision-making and stakeholder engagement and provide a foundation for establishing recommendations for the viable implementation of teleradiology in South Africa and other lower- and middle-income countries to promote access to healthcare.","PeriodicalId":43442,"journal":{"name":"SA Journal of Radiology","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10476222/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10170199","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study was conducted in a quaternary hospital, Charlotte Maxeke Johannesburg Academic Hospital (CMJAH), part of the University of the Witwatersrand teaching circuit, in South Africa.Objectives: To measure the clinicians' perceived benefits and challenges of PACS. To document perceived views on how the current PACS can be improved.Method: This was a cross-sectional observational study over a period of 5 months from September 2021 to January 2022 carried out at CMJAH. Questionnaires were distributed to referring clinicians with PACS experience. Descriptive statistics was conducted. Categorical variables were presented as frequency and percentages. The continuous variables were presented as means ± standard deviation.Results: A survey with a response rate of 54% found the benefits most reported by clinicians were improved patient care, less time needed to review an exam, improved image comparison and consultation efficiency. With respect to perceived challenges, the unavailability of images at the bedside, problems with access and the lack of advanced image manipulating software were noted. The most frequent recommendations on improvements focused on the aforementioned challenges.Conclusion: Hospital-wide PACS was viewed beneficial by most clinicians. Nonetheless, there are a few aspects that deserve attention to improve the functionality and access of the system.Contribution: The findings will assist in future hospital or provincial-wide PACS deployment projects.","PeriodicalId":43442,"journal":{"name":"SA Journal of Radiology","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10244939/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9612959","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
