ong>Background:ong> Cervical cancer is one of the most common cancers, requiring a precise complementary assessment. The aim of this study was to contribute to the improvement of the management of cervical cancer by describing the MRI aspects of cervical cancer according to the IFoG-MRI classification. ong>Material and Methods:ong> This was a cross-sectional study, conducted in patients who came for clinical suspicion, extension assessment of histologically confirmed cervical cancer, from october 2020 to March 2021, in Yaoundé (Cameroon). ong>Results:ong> 54 patients were selected, with an average age of 50.4 years. Genital hemorrhage was the most frequent symptom (92%). The mean tumor size was 52.9 mm. According to IFoG staging, stages Ia, Ib, IIa, IIb, IIIa, IIIb, and IV accounted for 9.10%, 10.20%, 12.50%, 29.50%, 5.70%, 12.50%, and 20% respectively. No patient had known metastasis at the time of examination. ong>Conclusion:ong> MRI allows non-invasive, satisfactory tumor staging examination by providing information on tumor size, parametrium invasion, adjacent organ involvement, and the presence of lymph node metastasis.

Introduction: The CoVID-19 pandemic has led to a massive influx of patients with suspected or confirmed flu to hospitals, paradoxically leading to a decrease in the attendance for some services. This study aspired to assess the impact of the CoVID-19 pandemic on the attendance of patients at the Radiology and Medical Imaging Department of a tertiary hospital in Douala, Cameroon. Materials and Methods: This was an observational, retrospective and descriptive hospital-based study. Data on patient attendance was extracted from the medical records at the Radiology Unit of Douala Gyneco-obstetric and Pediatric Hospital (DGoPH) between the 1st of March 2019 and the 30th of August 2021. Results: There was a drop in the number of sonographies and conventional radiographies by 25.73% and 18.26% respectively during the peaks pandemic period of 2020 compared to the preceding pre-pandemic era (2019). There was a recovery in 2021 as the numbers increased. Computed tomography studies increased by 40.65% during the peak pandemic period of 2020. Conclusion: This study enables us to understand the health-seeking behavior during the CoVID-19 pandemic. The increase in CT utilization during the peak period of the pandemic nevertheless required caution in order to ensure safety and to promote rational cost-effective utilization.

ong>Background:ong> The lumbar spine is the portion most frequently involved in degenerative pathologies. Everyone will suffer one day from “low back pain”. These pathologies are very frequent: epidemiological studies have shown that 65% to 90% of the general population could be affected by low back pain (lumbago) which could become chronic at acertain stage or could be complicated (2% to 4%) of cases could end up affecting nerve roots. Chronic low back pain causes a major public health problem in terms of morbidity and socioeconomic repercussions. ong>Purpose:ong> The overall purpose of this study is to evaluate the professional habits of exam applicants in case of degenerative pathologies of the lumbar spine, to Appreciate the knowledge of clinicians on the usefulness of medical imaging techniques in the event of suspicion of a degenerative pathology of the lumbar spine and finally to evaluate if the professional habits of requesting examinations in Cameroon comply with the Recommendations for Clinical Practice. ong>Methods:ong> A cross-sectional and descriptive study was used and was based on questionnaires distributed to those practitioners who requested for these diagnostic medical imaging studies and procedures at Yaoundé General Hospital (HGY), Yaoundé Central Hospital, La Cathédrale Medical Center, Yaoundé University Teaching Hospital, the Douala General Hospital, the Laquintinie Hospital of Douala, the Military Hospital of Douala, the Daniel Muna Memorial Clinic of Douala, the International Center for Clinical and Medicine Imaging, the Ngaoundere Regional Hospital and the Protestant Hospital of Ngaoundere (HPN), from April 2020 to March 2021. Data collected was processed and analyzed via Epi Info version 12.0 and the statistical test used for correlation was Chi2. ong>Results:ong> 137 practitioners were retained among whom, 90 were male and 47 females, their average age being 46 years with working experience less than 5 y

ong>Introduction: ong>Pregnancy is a physiologic state associated with decreased immunity, and the use of medical imaging modalities with ionizing radiation must be justified as potential benefits must outweigh the risk of any harm. However, in the wake of SARS-CoV-2 virus pandemic, chest computed tomography (CT) is necessary to assess the severity of the disease. The objective of this study was to compare the chest CT findings of pregnant and non-pregnant women with SARS-CoV-2 viral pneumonia at a tertiary hospital setting. ong>Materials and Methods: ong>This was a cross-sectional, retrospective, descriptive study of admission records of pregnant and non-pregnant patients aged 15 - 49 years during a three (3) months period (April-July 2020) in DGoPH. Logistic regression was used to search for predictors of lung involvement during CoVID-19. ong>Results:ong> A total of 31 patient files were studied of which 9 (29%) were those of pregnant women. The pregnant women mostly had a combination of lung ground-glass opacities and consolidation on CT compared to the non-pregnant women (7 out of 9 cases, 77.8%, vs. 6 out of 22 cases, 22.7%;p = 0.01). The group of pregnant women had more than 3 affected lobes (50.0% vs. 22.7%, p = 0.04) with a middle lobe predilection (77.8% vs. 31.8%, p = 0.02). CT predictors of CoVID-19 pneumonia in the group of pregnant women after the multivariable logistic regression analysis were the presence of nodules (aoR = 13.9;95% CI: 1.25 - 134.2;p = 0.032) and linear bands of interlobular septal thickening (aoR = 17.8;95% CI: 1.46 - 217.6;p = 0.024). ong>Conclusion: ong>In this study, the chest CT of pregnant women with CoVID-19 pneumonia revealed mostly a combination of findings compared to non-pregnant women, with more affected lobes. These findings suggest the likelihood of a greater CT severity of CoVID-19 pneumonia among pregnant women and therefore the need for timely and appropriate management.
