Introduction: radiology and medical imaging examinations bring together the means of acquiring and restoring images of the human body from different physical phenomena such as the absorption of X-rays, nuclear magnetic resonance, reflection of ultrasound waves or radioactivity, with which we sometimes associate optical imaging techniques such as endoscopy. The objective of our study was to study the profile of radiological examinations in the radiology and medical imaging department of the “KALALE” medical clinic. Methodology: This was a descriptive, prospective study that took place over a period of six (6) months in the radiology and medical imaging department of the “KALALE” medical clinic and the centers of health of communes III and IV of Bamako in Mali. Data collection was carried out on a survey form. The parameters studied were sociodemographic data, clinical data, radiological data. Results: We recorded 6030 radiology examinations of which 19% of the examination frequency cases came from the “KALALE” medical clinic and 81% of the cases were referrals from the reference health centers of communes III and IV. There were 1500 X-rays or 24.9% of cases including 54% cases of bone X-rays;5% of cases of skull and face X-rays;5% of cases of Intravenous Urography (IVU);4% of cases of Hysterosalpingography (HSG);3% of cases of Retrograde Ureterocystography (UCR) and 1% of cases of X-ray of the Abdomen without preparation (ASP). We found 4530 ultrasounds or 75.1% of cases. Conclusion: medical imaging has become essential in the study of the human body and now constitutes an essential tool for the detection and treatment of most pathologies, from simple fractures to the most serious tumors.

Hemangioblastomas are benign vascular tumors of the brain. These are rare tumors, usually located in the cerebellum and most often affecting young adults. The aim was to study the value of CT in the management of hemangioblastoma through observation. We report the case of a 38-year-old patient referred to the radiology and medical Imaging department of the Marie Curie medical clinic in Bamako, Mali, for an orbito-cerebral CT scan in a context of bilateral eyelid edema. The examination was performed using multi-slice computed tomography (16 slices) with reconstruction in the 3 planes of space without and with the injection of an iodinated contrast agent. The CT scan was crucial in making the diagnosis of hemangioblastoma incidentally, which allowed for adequate management. The patient was operated on, and the radiological outcome was favorable, without significant cystic formation, after postoperative control and clinical signs were resolved. CT can be an interesting alternative in countries like ours despite MRI being the examination of choice in hemangioblastomas.

Introduction: A thyroid nodule is a localized hypertrophy within the thyroid parenchyma. The aim of our study was to study the benefit of ultrasound in the Ti-rads classification of thyroid nodules. Methodology: This was a prospective study with a descriptive aim, with prospective collection, which took place over a period of 17 months at the “Marie Curie” medical clinic. The ultrasound machine used was a Voluson E8 from 2011 and the examinations were carried out by two radiologists and two experienced sonographers. The parameters studied were sociodemographic data;clinical data and ultrasound aspects of the Ti-rads classification in the management of nodules. Results: We collected 235 patients out of 738 patients referred to the service for a cervical ultrasound, i.e. a frequency of 31.84% of cases. There was a female predominance with 95.7% of cases and a sex ratio of 0.04. The average age of our patients was 50 years. We found on cervical ultrasound: Isthmo-lobar glandular hyperplasia in 99 patients, i.e. a frequency of 42.1%. The Ti-rads 3 classification was the most represented in 69.4% of cases. The benignity criterion represented 85.6% of cases in our patients and the malignancy criterion represented 14.4% of cases. Conclusion: The precise description of a thyroid nodule provided by ultrasound (Ti-rads) is essential in the management of nodules.

Biodegradable magnesium alloys have been widely used in medical implants. But safety concerns were put forward for the high degradation rate of biodegradable magnesium alloy. The optimal biodegradable magnesium alloys that give rise to the desired degradation rate hasn’t yet to be defined. Assessing the degradation rate of biodegradable magnesium alloys involves in vitro testing, in vivo testing, numerical modeling, understanding the factors influencing their degradation in physiological environments, biocompatibility testing, and clinical studies. It is important to standardize analytical tools aimed at assessing the degradation rate of biodegradable magnesium alloys. It is advisable to identify the threshold for safe degradation rate of biodegradable magnesium alloys in biomedical applications.
