The cephalic index is regarded as a useful anthropometric variable in medicine, forensic science and anthropology. There is limited data on the cephalic indices of Nigerian fetuses \u0000Objective: To check for variations of prenatal ultrasound-estimated cephalic indices between fetuses of Igbo, Yoruba and Hausa ancestry. \u0000Methodology: In a cross sectional study carried out in ultrasound diagnostic centres in Lagos, Enugu and Kano, all in Nigeria, fetal biparietal and occipitofrontal diameters were obtained from 200 fetuses each of Igbo, Yoruba and Hausa ethnic groups. The cephalic index was calculated for each group. The values were statistically analysed after deriving the relevant indices. \u0000Result: The fetal cephalic indices for Igbo, Yoruba and Hausa ethnic groups were observed to be 80 ± 3.4, 79.1 ± 5.1 and 78.4 ± 2.6 %, respectively. \u0000Conclusion: The results showed that fetuses of Igbo ancestry had a different cephalic index categorization from other ethnic groups.

The detector was positioned at the center of the collimated beam axis with focus-to-image distance (FID) of 100 cm. Tube potentials of 80 and 100 kVp were selected, and used to make exposures. The corresponding HVLs were then recorded. Also, x-ray field and light field congruence were measured by placing 18 cm x 24 cm cassette loaded with film at FID of 100 cm. The collimator light was in ON position and metal markers were used to delineate the periphery of the light field. Misalignment was calculated from the developed radiographs using standard formula. \u0000Results:The HVL ranged from 3.40 to 4.4mmAl.

Most of the earlier modalities that were largely analogue and mechanical have been replaced by automated and digitized technology. \u0000Objective: To track the developments and innovations in certain aspects of medical imaging that have impacted positively on patient care. \u0000Methods: Relevant literature were searched physically and online for both old and modern technological innovations in medical imaging and patient care. \u0000Results: There have been new technologies such as computed tomography, magnetic resonance imaging and the various ramifications of ultrasonography. Innovations in imaging modalities have brought increased diagnostic accuracy, much as examination time has been drastically shortened and radiation dose levels minimized or completely dispensed with. Manufacturing of portable equipment means that technology can now be taken to the patient and more time is dedicated to patient care. Introduction of digital radiography and Picture Archiving and Communication Systems have further impacted positively on efficiency and effectiveness of service delivery. Graduate degree programmes have invigorated radiographers’ drive for the discovery of new and better ways of diagnosis and treatment through research. \u0000Conclusion: Innovations in technology have led to miniaturization of equipment making it possible to take services to the critically ill patients, thereby improving patients’ accessibility to medical care. Also patients’ exposure to ionizing radiation has reduced due to improvement in research and development of new modalities using radiant energies other than ionizing radiation.
