Tuberculosis represents a main concern for public health worldwide. In poor countries, the most prevalent method for bacteriological confirmation remains Smear Sputum Microscopy (SSM). This study objective was to assess clinical performances of Loop Mediated Isothermal Amplification for TB detection (Lamp-TB). Sputum of patients presenting symptoms consistent with tuberculosis were collected according to the National Tuberculosis Control Programme guidelines in Centre Antituberculeux de Yopougon. SSM after Ziehl-Neelsen staining and TB-Lamp were blindly performed with spot sputum specimen. Samples, transported at Institut Pasteur de Côte d'Ivoire were decontaminated according to N-acetyl-L -cystein (NALC) method. In Mycobacteria Growth Indicator Tube (MGIT), 500 µl of pellet were inoculated and incubated in MGIT 960 instrument. MPT64 antigen was detected on positive culture. Of 500 patients enrolled, 469 were included. Clinical isolates of M. tuberculosis Complex were detected for 157 (33.5%). Comparatively to culture, Sensitivity and Specificity of SSM were 86% (95% Confidence interval (CI): 81% -91%) 96% (95%IC: 94% -98%) respectively. TB-Lamp Sensitivity was 92% (95%CI: 88% -96%), and Specificity 94% (95%CI: 91% -97%). Positive Predictive Value of SSM and TB-Lamp was 91.8% and 88.8% respectively. Negative Predictive Value of TB-Lamp assay was 95.7% whereas this of SSM was 93.3%. Positive Likelihood Ratio was 15.3 for TB-Lamp and 21.5 for SSM 21.5 whereas negative Likelihood of TB-Lamp was lower than SSM. Active tuberculosis was detected in162/469 (34.5%) with TB-Lamp and 147 (31.3%) with SSM. TB-Lamp assay performances estimated from sputum samples may improve detection of active TB cases in routine.

Introduction: Spondylolisthesis is defined as a permanent anterior sliding of the vertebral body accompanied by the pedicles, the transverse processes and the posterior joints in relation to the underlying vertebra. The prevalence of spondylolisthesis varies between 4% and 9%, according to different authors in France, China and Japan. In Africa, some African authors find a spondylolisthesis rate of 9.93%. The objective of this study was to study the clinical and radiological aspects of spondylolisthesis at the Mother-Child Hospital of Bamako. Methods: Prospective and retrospective descriptive study carried out in

Introduction: Malformations of the excretory tract are abnormalities due to a disorder of embryogenesis. According to some authors, their frequency varies from 0.30 to 5.25 per 1000. The aim of this study was to highlight the CT uroscan aspect of pyelic bifidity with intravesical ureteral ectopic junction revealed by a urinary calculus and to explain the interest of CT uroscan in the management of urinary pathologies. Result: We report the observation of a 37-year-old overweight patient with a body mass index equal to 28, a history of surgery and extracorporeal litho-thipsis dating back 10 years. He was referred to the Imaging Department in the context of renal colic. The uroscanner made it possible to highlight a left pyelic bifidity associated with an ec-

Purpose: The purpose of our study was to describe the technique of scanopelvimetry used in the radiology department of the Point G University Hospital, to specify the indications of scanopelvimetry in the department and to evaluate the cost of radiopelvimetry. Patients and Method: This was a prospective, cross-sectional study that took place over a 12-month period from January 1 to December 31, 2018. It focused on pregnant women in whom scanopelvimetry was performed in the medical imaging department of Point G University Hospital during the study period. Results: Out of 8615 CT examinations performed in the radiology department, we collected 65 cases of scanopelvimetry, i.e., 0.7% of the CT examinations. Primigravida and paucigravida dominated the study (40% each). In 60% of the pregnant women the height was less than 150 cm. The most frequent indication for CT scanning was clinical pelvic narrowing (50%). In 80% of the cases, the scanopelvimetry was performed after 37 weeks of amenorrhea. A predominance of narrowing of the superior strait was noted (40%). 4.6% of the pregnant women had a Magnin index of less than 20. CT scanopelvimetry is a feasible examination in

Our study was carried out at Robert BALLANGER Hospital, its aim was to determine the contribution of the scanner in the diagnosis of COVID-19. It was a prospective descriptive study during the first wave of the COVID-19 epidemic in France. Patients were referred to the medical imaging department for a thoracic CT scan without contrast injection or an angioscanner in the context of a suspected COVID-19 pneumopathy or pulmonary embolism. The study involved both sexes, the male sex was with 55.20% and sex ratio of 1.24. In our study 50% of our patients had a comorbid factor, of which diabetes and hypertension were the most represented with 33% and 17%. The RT PRC test is considered the gold standard in the diagnosis of COVID-19 disease. This test was positive in 63.62% of our patients. CT imaging played a key role in the management of COVID-19 pneumonia because chest CT scans found lesions consistent with COVID-19 pneumonia in 71% of patients. The depoliated lung lesion
