[Sorting and detection of COVID-19 by low-dose thoracic CT scan in patients consulting the radiology department of Fann hospital (Dakar-Senegal)].

Introduction: COVID-19 has spread rapidly since its emergence in China and is currently a global health issue. Its definitive diagnosis is made by PCR on nasopharyngeal swabs. However, this diagnostic test has low sensitivity with delayed results.

[Scannographic investigation in the diagnosis of inguinoscrotal bladder hernia].

We report the case of a 67-year old patient with a personal history of inguinal hernia, presenting with a large painless bag associated with urinary disorders, similar to pollakiuria, evolving for several months. Ultrasound allowed to reveal an emptiness in the bladder bag, urinary stasis and a collection of fluid in the scrotum, evoking a hydrocele. Abdominal/pelvic CT scan showed right intrascrotal bladder associated with left direct inguinal hernia and bilateral urinary stasis.

[The contribution of MRI in the management of slowly progressive nontraumatic spinal cord compression].

Slow spinal cord compressions are due to the development of an expansive lesion within the medullary canal. This is a very common condition whose diagnosis is primarily clinical. The magnetic resonance imaging occupies a central and currently irreplaceable position in diagnosis and localization as well as in etiological research.

[Role of biliary MRI in etiological diagnosis of cholestatic icteruses in Dakar].

Biliary MRI is a relatively new diagnostic test in the arsenal of exploration techniques in biliopancreatic pathology. This is a reproducible and reliable non invasive technique for direct visualization of biliary and pancreatic ducts. This study aims to evaluate the morphological features of major abnormalities and the role of biliary MRI in the etiological diagnosis of cholestatic icteruses.
