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.
