Objective: To determine the Computed Tomography (CT) patterns of intracranial infarctsDesign: A retrospective cross-sectional study.Setting: The CT scan unit of the Radiology Department, Cape Coast ...Teaching Hospital (CCTH), from February 2017 to February 2021Participants: One thousand, one hundred and twenty-five patients with non-contrast head CT scan diagnosis of is-chaemic strokes, consecutively selected over the study period without any exclusionsMain outcome measures: Patterns of non-contrast head CT scan of ischaemic strokes.Results: About 50.6% of the study participants were females with an average age of 62.59±13.91 years. Males were affected with ischaemic strokes earlier than females (p<0.001). The risk factors considered were, hyperlipidaemia (59.5%), hypertension (49.0%), Type 2 diabetes mellitus (DM-2) (39.6%) and smoking (3.0%). The three commonest ischaemic stroke CT scan features were wedge-shaped hypodensity extending to the edge of the brain (62.8%), sulcal flattening/effacement (57.6%) and loss of grey-white matter differentiation (51.0%), which were all significantly as-sociated with hypertension. Small deep brain hypodensities, the rarest feature (2.2%), had no significant association with any of the risk factors considered in the study.Conclusion: Apart from the loss of grey-white matter differentiation, there was no significant association between the other CT scan features and sex. Generally, most of the risk factors and the CT scan features were significantly associated with increasing age.
The novel corona virus popularly referred to as COVID-19 disease and SARS-CoV-2 was first detected in Wuhan, China in December 2019. It was declared a pandemic by the World Health Organization (WHO) ...on March 11, 2020. In Ghana, the first two cases of COVID-19 infection were recorded on March 13, 2020 with a strain imported from Europe. In December 2020, a new strain from South Africa was detected in Ghana which was associated with higher transmission rates, severity of the disease, and higher number of recorded deaths. Our study aimed to record notable differences and similarities between infections due to the initial, and second strains of COVID-19 infections detected in Ghana during the last 12-months.
This was a retrospective study involving 50 patients infected with the first strain, and another 50 patients infected with the second strain of the SARS-CoV-2 virus. Microsoft Excel-2013 was the analytical tool.
The data analysis supported publications suggesting that the new strain of the virus caused more severe infections, which were manifested on high resolution CT (HRCT) scans as more widespread alveolar disease, most commonly presenting as large areas of consolidation.
Despite numerous similarities in terms of the manifestation of COVID-19 infection on HRCT scans, notable difference supporting the notion of increased virulence and severity of disease were also recorded. The study findings demonstrate the need for heightened and sustained preventive measures needed to reduce, and eventually curb COVID-19 infection and mortality rates associated with the introduction of new virulent strains.

Background
There is an inadequate number of radiologists in Ghana whose distribution are skewed in favour of urban areas, creating a huge service gap with the few radiologists overburdened with work. ...The only way to bridge this service gap while increasing numbers of radiologists by training is from the application of information communication technology (ICT), hence this study.
Methods
This was a cross-sectional questionnaire administered study conducted between 16th - 18th May 2019 during the annual general meeting of the Ghana Association of Radiologists involving 46 consented radiologists. The questionnaire investigated the available ICT tools, imaging modalities, the degree of usage and impacts of ICT on radiologists work output.
Results
The most available modalities were digital. 13.0% had teleradiology available, but 32.6% were familiar with it. All radiologists indicated improvement in work output with ICT. The time taken to report a case reduced from 1-2 hours to 10-30 minutes with ICT. Majority did not communicate professional issues via e-mails. 95.7%, 13.0% and 10.9% of radiologists used WhatsApp, Facebook and Twitter respectively to communicate radiological information. Online research provided significant information for their radiological reporting.
Conclusion
The topmost four imaging modalities readily available were Digital Ultrasound, Digital Radiography, Computed Tomography scan and Magnetic Resonance Imaging. The availability of and familiarity with teleradiology was low in radiological practices. The reporting time per case and work output of radiologists were improved with ICT. The two most common social media platforms used by radiologists were WhatsApp and Facebook.
Background
There is a high demand for medical sonographers, mainly due to high antenatal and other ultrasound examinations. Ghana has 334 registered radiographers and sonographers for a population of ...30 million. The non-existence of strict enforcement of mandatory credentialization and licensure for the practice of ultrasonography has made the proliferation by quacks very pervasive in Ghana. However, there is inadequate knowledge about the activities of these unlicensed sonographers. This paper looks at the scale, creation, proliferation, and patronage of unlicensed Sonographers and discusses the impact on Ghana’s health care delivery.
Methods
The study was a qualitative study using well-structured pretested questionnaires administered to unlicensed sonographers – multiple techniques were used in data collection. Sonographic reports emanating from unlicensed sonographers brought by referred patients to a tertiary hospital were also collated and analyzed.
Results
A total of 207 unlicensed sonographers were recruited for the survey. The results showed 90% (186) response rates out of which 128 (69%) were males and 58 (31%) were females. All participants were above 25 years. 46.8% of unlicensed sonographers had senior high school (SHS) or tertiary (41.4%) education. Four pathways identified for their proliferation, 32.8% trained by attending sonography short courses, 32.2% by Peer-to-peer hands-on training, 32.2% by unaccredited training schools, 3.8% attended sonography workshop, and 1.0% had no form of training. Radiologists 33%, Licensed Sonographers 29%, Medical Doctors 20%, unlicensed sonographer 16%, and midwives 2% were responsible for their training. The majority (67.2%) worked in hospitals, and 29.6% in diagnostic centers. The facilities’ ownership structure showed 66.7% privately owned, 15.8% government-owned, 14.2% owned by the Christian Health Association of Ghana (CHAG), faith-based health facilities, and 3.3% of respondents set up their personal ultrasound scan center. The majority (82.2%) of respondents believed sonography practice must be rigorously regulated. The overwhelming majority (95.5%) wanted practicing unlicensed sonographers to be allowed to upgrade at accredited ultrasonography schools leading up to their appropriate licensing.
Conclusions
Regulators must stringently implement guidelines regulating the practice of ultrasound to safeguard patients. However, the 334 licensed sonographers in Ghana is woefully inadequate; therefore, unlicensed sonographers must be persuaded and supported to upgrade. Policy direction is to increase accredited ultrasonography training institutions to facilitate the training of more medical sonographers.
