Estimation of gestational age using trans-cerebellar diameter: a sonographic study of a cohort of healthy pregnant women of Igbo ethnic origin in a suburb of Lagos, southwest Nigeria.

Aim: To use a sonographic method to determine the usefulness of trans-cerebellar diameter (TCD) as an independent estimator of gestational age (GA).

Methods: A convenience sample of 257 healthy pregnant women of Igbo ethnic origin with singleton normal pregnancy whose GA ranged from 16 to 40 weeks were examined. GA was calculated from the date of onset of the last menstrual period (LMP) and was used as the standard criterion, while the biparietal diameter (BPD), head circumference (HC), abdominal circumference (AC), and femur length (FL) were used to estimate GA.

Sonographic evaluation of kidney echogenicity and morphology among HIV sero-positive adults at Lagos University Teaching Hospital.

Aim: To evaluate the role of kidney echogenicity and morphology in the diagnosis of human immunodeficiency virus-associated nephropathy (HIVAN).

Subjects And Methods: In the cross-sectional study, a sample of 340 anti-retroviral therapy (ART)-naïve AIDS patients underwent laboratory CD4+ count, serum creatinine determination and sonographic renal echogenicity grading and size measurement. Rounded kidneys were described as bulbous while bean-shaped kidneys were described as reniform; echogenicity was categorized into grades 0, 1, 2 and 3.

Reliability of Sonographic Estimation of Fetal Weight: A Study of Three Tertiary Hospitals in Nigeria.

Context: There is a dearth of sonologists in Nigeria, yet sonographic estimation of actual birth weight (ABW) is important in antenatal care.

Aim: To determine the reliability of estimated fetal weight (EFW) by sonographers and sonologists in Lagos Nigeria.

Settings And Design: In the cross-sectional study, a convenience sample of 663 healthy women with singleton pregnancy at term was selected.

Correlation of ultrasonographic estimated fetal weight with actual birth weight in a tertiary hospital in Lagos, Nigeria.

Background: Sonographic fetal weight estimation is an important component of antenatal care.

Aim: To sonographically estimate fetal weight at term and to compare estimated with actual birth weights to determine the validity of estimated fetal weights.

Subjects And Methods: In the prospective study, a convenience sample of 282 women was recruited.

Assessment of radiation protection practices among radiographers in Lagos, Nigeria.

Background: Use of ionising radiation in diagnostic radiography could lead to hazards such as somatic and genetic damages. Compliance to safe work and radiation protection practices could mitigate such risks. The aim of the study was to assess the knowledge and radiation protection practices among radiographers in Lagos, Nigeria.

CT-detected intracranial hemorrhage among patients with head injury in Lagos, Nigeria.

Purpose: To evaluate the computed tomography (CT) findings of intracranial hemorrhage among patients with head trauma in Lagos, Nigeria.

Methods: In this retrospective, cross-sectional study, a convenience sample of 500 patients with head trauma who had diagnostic cranial CT scans was selected. All the radiological reports and CT scans of patients with head trauma were retrieved in the hospitals selected as study sites.

Ultrasonographic kidney sizes among children in Benin, Nigeria: correlation with age and BMI.

Purpose: To determine kidney sizes among Nigerian children using ultrasonography to provide local reference data that could be compared with renal growth charts when assessing kidneys of Nigerian children for growth or pathology.

Methods: The study design was cross-sectional and a convenience sampling technique was used to select a sample. Consent was obtained from participants and ethical approval was obtained from the local ethics committee.
