Item An audit of clinical practice, referral patterns, and appropriateness of clinical indications for brain MRI examinations: A single-centre study in Ghana(Radiography, 2018-05) Piersson, A.D.; Nunoo, G.; Gorleku, P.N.Introduction The aim of this study was to investigate current brain MRI practice, pattern of brain MRI requests, and their appropriateness using the American College of Radiology (ACR) Appropriateness Criteria. Material and methods We used direct observation and questionnaires to obtain data concerning routine brain MRI practice. We then retrospectively analyzed (i) demographic characteristics, (ii) clinical history, and (iii) appropriateness of brain MRI requests against published criteria. Results All patients were administered the screening questionnaire; however, no reviews were undertaken directly with patients, and no signature of the radiographer was recorded. Apart from routine brain protocol, there were dedicated protocols for epilepsy and stroke. Brain MRI images from 161 patients (85 Males; 76 Females) were analyzed. The age group with most brain MRI requests were from 26 to 45 year olds. The commonest four clinical indications for imaging were brain tumour, headache, seizure, and stroke. Using the ACR Appropriateness Criteria, almost 43% of the brain MRI scans analyzed were found to be “usually appropriate”, 38% were “maybe appropriate” and 19% were categorized as “usually not appropriate”. Conclusion There was knowledge gap with regards to MRI safety in local practice, thus there is the utmost need for MRI safety training. Data on the commonest indications for performing brain MRI in this study should be used to inform local neuroradiological practice. Dedicated stroke and epilepsy MRI protocols require additional sequences i.e. MRA and 3D T1 volume acquisition, respectively. The ACR Appropriateness Criteria is recommended for use by the referring practitioners to improve appropriateness of brain MRI requests.Item Career in radiology; the ghanaian clinical medical Student's perception(Heliyon, 2022) Dzefi-Tettey, K.; Edzie, E.K.M.; Brakohiapa, E.K.; Gorleku, P.N.; Amankwa, A.T.; Abdulai, A.B.; Yabasin, I.B.; Kekessie, K.K.; Idun, E.A.; Ntiamoah-Koufie, C.E.; Acheampong, F.; Oppong, B.; Quarshie, F.; Kusodzi, H.; Asemah, A.R.Background: The importance of radiology in this era of evidence-based medicine cannot be disputed. This has resulted in the increase in demand for radiologists. Thus, the issue of whether there would be sufficient numbers of medical students to meet this growing demand needs further probing. Purpose: To assess Ghanaian clinical medical students’ perceptions about a career in radiology. Materials and methods: This was an online questionnaire-based survey of 575 clinical medical students in five public medical schools in Ghana from September 2020 to February 2021. Student's t-test and one way analysis of variance was used to compare means. For the Likert scale questions, differences in the mean Likert scale responses were assessed among various clinical year groups and across gender using Kruskal-Wallis test and Mann–Whitney U tests. A logistic regression was used to determine the significant predictors of the choice of radiology as a career. Results: Most 340 (59.1%) of the participants were males. The average age of participants was 24.64 3.084 years. Students agreed that, radiology is relevant in this era of evidence-based medicine (mean Likert score ¼ 4.62, SD ¼ 0.819), which yielded significant responses in the third clinical year (p ¼ 0.004). Nearly 30% of respondents stated they did not receive enough didactic lectures or tutorials in radiology, citing insufficient lectures (89.9%), a lack of lecturers (9.5%), and trouble grasping ideas (0.7%) as their main concerns. 133 (23.1%) stated they would choose radiology as a specialty, with flexible working schedule (61.9%) and high income (68.3%) as their topmost reasons. Less patient contact (8.0%) was the least observed reason. A flexible working schedule increased the choice of radiology as a specialty by 2.319 folds (95% CI: 1.413–3.805, P ¼ 0.001). Teleradiology significantly contributed to the choice of radiology as a career (p ¼ 0.001). Conclusion: Generally, the clinical students had varied but positive perceptions on radiology as a specialtyItem The degree and appropriateness of computed tomography utilization for diagnosis of headaches in Ghana(Heliyon, 2021) Gorleku, P.N.; Dzefi-Tettey, K.; Edzie, E.K.M.; Setorglo, J.; Piersson, A.D.; Ofori, I.N.; Brobbey, I.F.; Fiagbedzi, E.W.; Brakohiapa, E.K.K.Introduction: Headache is a common and sometimes debilitating medical condition. Patients presenting with no neurologic anomaly, nontraumatic primary headache require careful evaluation before neuroimaging. National Guidelines standardizing exploitation of Computed Tomography (CT), the most utilized imaging modality in this clinical scenario, has not been established in Ghana, a developing country with limited healthcare resources. The country has not also adopted existing guidelines such as the National Institute for Health and Care Excellence (NICE) of the United Kingdom or the Appropriateness Criteria (AC) of the American College of Radiologists (ACR). The purpose of this review was to analyze the propensity of CT utilization for diagnosing headaches against the AC of the ACR and discuss some of the socio-economic inferences thereof. Methods: This study retrospectively reviewed CT imaging records and clinical data of all patients referred for head CT scans between 1st January 2016 and 31st December 2018 at five major health facilities (four tertiary government hospitals and one private hospital) across Ghana. We isolated all head CT scans performed for the diagnosis of headache for analysis. We analyzed the type of presenting headache, CT findings, gender distribution, pattern of referrals, and head CT appropriateness against the AC of the ACR. Results: A total of 44,218 patients were referred to the five facilities for head CT secondary to diverse indications for the period. All non-trauma cases were 41.7%; trauma cases were 31.6%, the majority (72.3%) were from road traffic accidents. The majority (64.9%) of trauma casualties were males.Atotal of 11,806 (26.7%) patients were referred for a head CT scan for the diagnosis of headache. The private hospital recorded the highest referrals for head CT scan for diagnosis of headache. The gender distribution of all headache patients was 57.6% females, and 42.4% were males. The age distribution showed 19.3% were children, 71.2% were adults, and the aged constituted 9.4%. The results showed 2.8% significant cranial CT findings of all reviewed headache patients. Pathological findings among the cohort of children were 0.6%. The sources and pattern of referrals showed 57.3% were from the Outpatient Department, 26.6% from the Emergency Department, in-patients’ referrals were 9.4%, and specialist consultation was 7.1%. Analysis of CT scans performed against the AC of the ACR, showed 69.0% of headache patients were likely scanned inappropriately. Conclusions: There is a need to implement international best practice guidelines or develop a national neuroimaging policy to protect patients. Unjustified CT utilization for diagnosis of headaches exposes patients to unnecessary ionizing radiation that can instigate cancer and unnecessary expenditure. Head CT scan for some headache patients with normal neurologic findings may be unnecessary in an emerging country like Ghana. Clinicians must, therefore, be discerning in CT scan requests for the diagnosis of headache.Item Pattern of chest computerized tomography scan findings in symptomatic RT-PCR positive Covid-19 patients at the Korle Bu Teaching Hospital, Ghana(African Health Sciences, 2022) Dzefi-Tettey, K.; Edzie, E.K.M.; Gorleku, P.N.; Brakohiapa, E.K.; Acheampong, F.; Asemah, A.R.; Kusodzi, H.; Saaka, P.S.; Idun, E.A.; Amankwa, A.T.Background: Chest Computerized Tomography (CT) features of Corona Virus Disease 2019 (COVID-19) pneumonia are nonspecific, variable and sensitive in detecting early lung disease. Hence its usefulness in triaging in resource-limited regions. Objectives: To assess the pattern of chest CT scan findings of symptomatic COVID-19 patients confirmed by a positive RTPCR in Ghana. Methods: This study retrospectively reviewed chest CT images of 145 symptomatic RT-PCR positive COVID-19 patients examined at the Radiology Department of the Korle Bu Teaching Hospital (KBTH) from 8th April to 30th November 2020. Chi-Squared test was used to determine associations among variables. Statistical significance was specified at p≤0.05. Results: Males represent 73(50.3%). The mean age was 54.15±18.09 years. The age range was 5 months-90 years. Consolidation 88(60.7%), ground glass opacities (GGO) 78(53.8%) and crazy paving 43(29.7%) were the most predominant features. These features were most frequent in the elderly (≥65years). Posterobasal, peripheral and multilobe disease were found bilaterally. The most common comorbidities were hypertension 72(49.7%) and diabetes mellitus 42(29.2%) which had significant association with lobar involvement above 50%. Conclusion: The most predominant Chest CT scan features of COVID-19 pneumonia were GGO, consolidation with air bronchograms, crazy paving, and bilateral multilobe lung disease in peripheral and posterior basal distribution.Item Pattern of chest computerized tomography scan findings in symptomatic RT-PCR positive Covid-19 patients at the Korle Bu Teaching Hospital, Ghana(African Health Sciences, 2022) Dzefi-Tettey, K.; Edzie, E.K.M.; Gorleku, P.N.; Brakohiapa, E.K.; Acheampong, F.; et al.Abstract Background: Chest Computerized Tomography (CT) features of Corona Virus Disease 2019 (COVID-19) pneumonia are nonspecific, variable and sensitive in detecting early lung disease.
