Prabhu","doi":"10.4103/wajr.wajr_16_21","DOIUrl":"https://doi.org/10.4103/wajr.wajr_16_21","url":null,"abstract":"Aims and Objectives: To observe the characteristics of primary central nervous system lymphoma (PCNSL) and high-grade glioma (HGG) in diffusion-weighted imaging (DWI), perfusion-weighted imaging (PWI), susceptibility-weighted imaging (SWI) and spectroscopy, and differentiate them based on these parameters. Materials and Methods: A total of 45 patients diagnosed with the central nervous system (CNS) neoplasm on magnetic resonance imaging (MRI) using 1.5 Tesla MRI Siemens Magnetom Avanto (Siemens, Germany) and with subsequent histopathological evidence as glioblastoma or CNS lymphoma were included. The study was completed over a period of 2 years. Results: It was found that DWI is effective in the differentiation of HGGs and PCNSLs. A total of 20 (57.1%) HGGs showed diffusion restriction, whereas 9 (90%) of the PCNSLs showed diffusion restriction. The mean apparent diffusion coefficient (ADC) (×10–6 mm2/s) in PCNSLs was 646 whereas, in HGGs, it was found to be 824.3. Thirty-one (88.6%) of the HGGs showed increased perfusion. The mean value of rCBVmean in HGG was found to be 4.06 and the mean value of rCBVmax was 3.63. None of the PCNSLs showed increased perfusion. The mean value of rCBVmean in PCNSLs was 0.097 and rCBVmax was 0.133. 30 (85.7%) of HGGs showed significant areas of blooming on SWI (in the form of intratumoral susceptibility signals [ITSS]). None of the PCNSLs showed blooming. All HGGs and PCNSLs showed increased choline and decreased N acetyl aspartate (NAA) on spectroscopy. Mean Choline/Creatine (Cho/Cr) in HGGs was found to be 3.06, whereas in PCNSLs, it was 1.84. Conclusion: It is important to make a distinction between HGG and PCNSL as the treatment modalities are different for both. Multiparametric evaluation of ADC, ITSS, and rCBVmean allows the differentiation of PCNSLs and solid glioblastoma which supports the integration of advanced MR imaging techniques including DSC-PWI, DWI, and SWI for the routine diagnostic workup of these tumors.","PeriodicalId":29875,"journal":{"name":"West African Journal of Radiology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43776354","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Moreover, clinicians need to clearly justify their requests for radiological procedures on a request form to prevent unnecessary radiation exposures and examinations with attendant prolonged waiting time. Objective: The study audited inadequately filled radiology request forms to determine their impacts on diagnosis, patient radiation exposure, and waiting time. Materials and Methods: Following an institutional review board approval, a total of 158 inadequately filled request forms for conventional X-ray examinations were sequentially enlisted and evaluated. Scorings as filled, inadequately filled, and unfilled were used to score each item based on the following: patient biodata/demographic information and patient referral details and referring physician details. Request forms for repeat examinations were further analyzed for remote factors tied to inadequate filling or lack of filling of the details on the repeat forms. Data were analyzed based on descriptive statistics using SPSS statistical software. Results: Patient names including first and surname were adequately filled on all the request cards (100%). Information related to patient referral details such as previous X-ray examination, blood pressure, and last menstrual period were inadequately filled with 4.4%, 2.5%, and 19.7% completion, respectively. Of the 158 request forms assessed, 33 (20.9%) examinations were repeated due to partial or complete cutoff of anatomic region of interest analysis showing inadequate clinical history and requested examination accounting for 45.5% and 24.2% of the remote factors tied to the repeats. Conclusion: The practice of adequate, correct, and consistent filling of radiology request forms was suboptimal with resultant prolonged waiting time and possibly increased exposure among repeat cases. A continued reminder of all referring clinicians needs to be improved to protect patients from prolonged waiting times and unnecessary radiation exposure, for the overall improvement of quality of services. Implications for Practice: Adequate information on the request forms improves diagnostic acuracy, reduced waiting time, and increased overall quality of service delivery.","PeriodicalId":29875,"journal":{"name":"West African Journal of Radiology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43868798","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Appendicitis often creates the most common abdominal surgical emergency. Ultrasound and computed tomography are often the imaging modalities used to confirm the clinical diagnosis of appendicitis. The aim of this study was to evaluate the accuracy of ultrasound in the diagnosis of appendicitis in a tertiary hospital in South Eastern, Nigeria. Materials and Methods: A retrospective study design was adopted to study 152 records of patients aged 1–65 years who had ultrasound scans for clinical suspicion of appendicitis at a tertiary hospital in Anambra State, South Eastern Nigeria from 2016 to 2018. Patients' age, gender, and provisional diagnosis were obtained from the patients' request forms. Ultrasound results were obtained from the radiology department and the histology reports from the histology unit of the hospital. The Statistical Package for the Social Sciences, SPSS, version 22.0. was used for data analysis. Results: Of the 152 cases, ultrasound was positive in 115, while histology confirmed 136 positives. Ultrasound, therefore, had a sensitivity, specificity, and accuracy of 84.56%, 100%, and 86.18%, respectively. The positive predictive value and negative predictive values were 100% and 43.24%, respectively. The study showed a higher incidence of appendicitis among females (n = 84) than males (n = 52), (ratio 1:1.6). Age groups 10–19 and 20–29 years were the most affected. Accuracy was 91.94% (in males) and 82.22% (in females). The most common ultrasound features include enlarged appendix (>9 mm, 100%), rebound tenderness to probe (92%), and fluid-filled appendix (88%).

The use of computed tomography (CT) attenuation values of the lumbar spine to estimate bone mineral density has been validated by several studies. Materials and Methods: This was a retrospective study conducted at Sweden Ghana Medical Centre and Korle Bu Teaching Hospital between June 2016 and August 2019. Measurement of Hounsfield unit (HU) of lumbar vertebrae was achieved by drawing an elliptical region of interest (ROI) on an axial image of the vertebra about 2–3 mm from the spinal cortical bone. The mean HU of the ROI was measured on bone window for each of the vertebral bodies, and the values were documented and analyzed. Results: The mean bone densities of the vertebrae were generally higher for the noncancer patients compared to the breast cancer patients for all the age groups. The measured bone densities showed a normal distribution curve. The range of bone density for osteopenia and osteoporosis was between 174.4 and 236.4 HU and <174.4 HU, respectively. A Pearson's correlation analysis between patient age and bone density for both groups showed a negative statistically significant relationship. Conclusion: Using CT attenuation values of lumbar vertebra to estimate bone density established that the bone densities follow a normal distribution, the mean bone density for breast cancer patients were slightly lower than for noncancer patients, and age correlated better with lumbar bone density in noncancer patients than in breast cancer patients.","PeriodicalId":29875,"journal":{"name":"West African Journal of Radiology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48419664","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the sensitivity of mammography decreases with high breast density found in younger age group. Ultrasound is considered as the first-line examination in the classification of breast density and in the detection and characterization of breast lesions. This study aims to evaluate the relationship between age and ultrasonographic breast density pattern and its implication for breast cancer risk. Materials and Methods: This was a community-based cross-sectional, exploratory, descriptive study involving 658 females. Breast ultrasonographic scans were performed using a Sonoace X1 Machine with a 7.5 MHz transducer. The lesions detected and classified by ultrasonography as benign or malignant were further subjected to cytopathology. Results: Modal age group of the participants ranged from 33 to 43 years representing 29.8%. There was significant correlation (P<0.01) between ultrasonographic mammary gland density pattern and age, the age group of <33 years demonstrated predominant fibroglandular density pattern with mostly benign lesions, while the age group of 33–53 years demonstrated predominant heterogeneous breast density pattern with most of the malignant lesions in this age group, making it the high-risk group for breast cancer. Conclusion: The relationship between age and ultrasonographic breast density is inversely proportional and not absolute. It also concludes that ultrasonography is a reliable screening tool in the diagnostic process for mammary gland lesions, and as an imaging tool, it is the preferred modality in dense breast. The heterogeneous fibroglandular pattern emerged as the high-risk group for breast cancer, especially in middle age.","PeriodicalId":29875,"journal":{"name":"West African Journal of Radiology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41270566","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Very few of such cases have been reported globally. To the best of my knowledge, no case on RLV has been reported in Ghana and as such, this case study is likely to be the first reported case in Ghana. A 27-year-old pregnant woman reported to the hospital with complains of bilateral inguinal swelling accompanied with intermittent excruciating pain. The swellings are visible with the woman in the standing position but disappear with the woman lying supine. The swellings are however prominent in the supine position on Valsalva maneuver. The woman was diagnosed with bilateral inguinal hernia and was scheduled for possible surgery after delivery. Dilatation of the vasculature of the round ligament presents as a bulging mass within the inguinal canal, mimicking inguinal hernias when examined physically. The distinction between the two, thus, the RLV and inguinal hernia is established with ultrasound scan examination. Diagnosing RLVs require the use of a color/power Doppler ultrasound machine and also well-trained clinical personnel with sonographic expertise. Ultrasound scan has been recognized to diagnose RLV effectively and to produce a clear-cut distinction from inguinal hernia. Accurate diagnosis of RLV is also essential to avoid unnecessary surgical interventions since the condition is noted to mostly resolve by itself after delivery.","PeriodicalId":29875,"journal":{"name":"West African Journal of Radiology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42817227","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is a routine procedure for evaluating female factor infertility in our environment where the incidence of tubal factor infertility is high. It is associated with varying degrees of discomfort and pain. The study aimed at comparing the efficacy of topical analgesia to a placebo for providing pain relief in women undergoing HSG as workup for infertility. Subjects and Methods: The study was a double-blind, parallel group randomized controlled trial of 117 infertile women who had HSG at the Ahmadu Bello University Teaching Hospital, Zaria, from February to December 2019. The intervention group (n = 59) and the control (n = 58) had 15 ml of 2% xylocaine gel and 15 ml of K-Y jelly (placebo) applied directly on their uterine cervical lip, respectively. The primary outcome measure was the mean Visual Analog Scale (VAS) for pain perception on each group during HSG at the point of cervical manipulation and uterine filling with contrast. Results: The mean VAS scores for pain perception in the xylocaine group during cervical manipulation and uterine filling were 2.3 (0.24) and 3.5 (0.35), respectively, while the scores for the placebo group during cervical manipulation and uterine filling were 7.1 (1.8) and 5.5 (0.32), respectively. The observed difference was statistically significant (P ≤ 0.001). Conclusion: During HSG of infertile women in Zaria, Nigeria, the use of topical xylocaine on the uterine cervix was associated with decreased pain perception during cervical manipulation and uterine filling with contrast when compared to placebo. “Trial registry: Www.clinicaltrials.gov, Identifier NCT03802032.”","PeriodicalId":29875,"journal":{"name":"West African Journal of Radiology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48859685","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
