Sonographic evaluation of maternal uterine artery from 11 - 30 weeks 6 days of gestational age in a Nigerian population: A predictive index for pre-eclampsia and intrauterine growth restriction.

Introduction: Uterine artery (UtA) Doppler sonography is a potential screening tool for pregnancy complications in placental insufficiency. Evaluation of the maternal and fetal vessels in pregnancy ensures accurate identification and prediction of pregnancy complications, such as preeclampsia (PE) and intrauterine growth restrictions (IUGR). The study aims to establish local reference values for UtA in a Nigerian population.

A review of MRI studies in Africa with special focus on quantitative MRI: Historical development, current status and the role of medical physicists.

This scoping review provides overview on the historical and major developments, current status, quantitative magnetic resonance (MR) studies and the role of medical physics bodies in MR imaging in Africa. The study analyzed MRI availability in 32 (59 %) of the 54 African countries. South Africa and Egypt have the most dominant MR systems.

Bone mineral density in an urban and a rural children population-A comparative, population-based study in Enugu State, Nigeria.

Introduction: Osteoporosis is one of the non-communicable diseases linked to urbanisation. The foundation of osteoporotic fractures stems from childhood. Therefore, studies that promote maximising peak bone mass are strongly advocated.

Calcaneal Broadband Ultrasound Attenuation and Speed of Sound Measurements in a Population of Nigerian Children: Reference Data and the Influence of Sociodemographic Variables.

Objectives: The aim of our study was to establish a reference database of calcaneal broadband ultrasound attenuation (BUA) and the speed of sound (SOS) in a healthy Nigerian population of children aged 6 to 14 years and also to investigate the influence of sociodemographic and anthropometric variables on them.

Methods: The BUA and SOS of 1016 healthy children were measured by quantitative ultrasound densitometry. Height and weight were measured with a stadiometer and weighing balance, respectively, whereas the sociodemographic parameters of the participants were collected on a semistructured questionnaire.

Sonographic assessment of petroleum-induced hepatotoxicity in Nigerians: does biochemical assessment underestimate liver damage?

Background: Exposure to petroleum products has been shown to have significant adverse effects on the liver which can manifest either as morphological or physiological changes.

Objectives: The aim of the study was to assess the effects of chronic exposure to some petroleum products on the liver of exposed workers using sonography and to determine whether biochemical assessments underestimated hepatotoxicity.

Methods: Abdominal ultrasound was performed on 415 exposed workers in order to evaluate liver echogenicity and size.

Transvaginal Sonography: perception and attitude of Nigerian women.

Background: To assess the attitude to and perception of transvaginal sonography (TVS) among Nigerian women of mixed educational status in order to ascertain factors that may prevent them from submitting to TVS when recommended.

Methods: A Cross-sectional survey was adopted for the study. In all, one missionary, one government and eight private hospitals were enlisted.

Assessment of women's attitude to and perception of transvaginal sonography in Nigeria.

Purpose: To assess the attitude to and perception of transvaginal sonography (TVS) among Nigerian women of mixed educational status in order to ascertain factors that may prevent them from submitting to TVS when recommended.

Methods: A Cross-sectional survey was adopted for the study. Subjects were enrolled from one missionary, one government and eight private hospitals.

Assessment of natural radioactivity in phosphate ore, phosphogypsum and soil samples around a phosphate fertilizer plant in Nigeria.

The radionuclides present in phosphate ore, phosphogypsum and soil samples in the vicinity of a phosphate fertilizer plants in Nigeria were identified and their activity concentration determined to assess the potential radiation impact on the environment due to fertilizer production. The mean activity concentration of (238)U, (232)Th, and (40)K radionuclides in phosphate ore samples were 616 ± 38.6, BDL (Below Detection Level) and 323.

The effect of in-vivo intravenous administration of sodium meglumine diatrizoate on some haematological parameters.

Background: To investigate the in-vivo effects of intravenous administration of sodium meglumine diatrizoate on some haematological parameters in a Nigerian population.

Methods: Blood samples were collected before and one hour after intravenous injection of sodium-meglumine diatrizoate from 50 subjects undergoing intravenous urography examinations who had no history of and laboratory confirmed diseases that may affect haematological parameters. Standard laboratory methods were used to assay the haemoglobin concentration (Hb), packed cell volume (PCV), total white blood cell (WBC) count and differentials and blood film for any morphological changes in the red blood cells (RBC).
