Over time x-ray department gains more patient throughput compared to when it was established, this may lead to changes in room usage, workload and occupancy factor. Therefore, it becomes imperative to re-evaluate the shielding adequacy of the facilities to ensure the appropriate shielding design goal is accomplished. The study was aimed at assessing the shielding adequacy of conventional x-ray rooms in ten radio diagnostic centres in Kano Metropolis using RADSHIELD software. This was a prospective, cross-sectional study. RadShield software version 1.1 was used in the study, parameters such as distances of each wall from a radiation source (D), the average number of patients per week (N), occupancy factor (T), and use factor (U) were inserted into the software together with the shielding design goal (P). Once the result was generated, the design and shielding variables were saved in .xml format. The data were analyzed using Excel 2016. Ten facilities were studied involving 14 x-ray rooms. Room III had the largest room size of 49.2 m2 while room X had the least room size of 12.8 m2. Room II had the longest source image distance (SOD) of 180cm while room IV had the shortest (120cm). The design barrier thickness was thickest (47 cm) in room II and thinnest (1.5 cm) in barrier 5 of room III. All the x-ray rooms had the ideal room size except facilities G and H. The design barrier thickness in the radiology department of all the conventional x-ray rooms involved in the study was adequate.

Retain products of conception (RPOC) remains a major concern because its complications are among the leading cause of morbidity and mortality among women with postpartum uterus. Every locality should have a documented findings of postpartum uterus predicting retained products of conception. This study was aimed at evaluating the sonographic pattern of RPOC among women attending Murtala Muhammad Specialist Hospital, Kano. The study was prospective, conducted from January 2021 to August 2021. A total of 200 patients referred on the suspicion of RPOC on the basis of history or clinical examination were enrolled in the study. Transabdominal ultrasound with 3.5MHtz transducer was performed in all referred cases. The findings obtained were recorded on data capture sheet. Data was analyzed using SPSS Version 23.0. Mean age of the patients was 21.7 ±6.7 years and the mean gestational age was 11.7 ±4.8 weeks. Most of the patients present with per vaginal bleeding, lower back pain or fever as their clinical history. Sonographic findings of RPOC were mix-echogenic content 106(53%), hypoechoic fluid collection 52(26%) and hyperechoic mass 42 (21%). The correlation between clinical history and sonographic pattern of RPOC shows a significant weak positive correlation (r= 0.15 and p= 0.03). The correlation between RPOC size and gestational age also shows a significant weak positive correlation (r= 0.27 and p= 0.00). Sonography is an accurate tool for diagnosis of retained products of conception, with mixed echogenic content as the most common sonographic pattern RPOC.
