Preliminary outpatient investigations revealed thrombocytopaenia 90(platelets per microliter), and a pelvic spleen on abdominal ultrasound. Contrast enhanced CT of the abdomen and pelvis in the portal venous phase confirmed a pelvic spleen with torsion of the splenic hilum. The spleen appeared hypoechoic on ultrasound. On CT, the spleen had heterogeneous enhancement with some irregularly shaped regions of hypoenhancement. There was a swirl (at least two complete turns) in the splenic vascular pedicle in the left abdomen. The splenic artery demonstrated some enhancement, but no enhancement of the splenic vein. The pancreatic tail was also involved in the torted vascular pedicle. No pancreatic duct dilation, and no infarct of pancreatic parenchyma were found. A small amount of free fluid around the spleen was found with no free gas. The portal vein enhanced normally. Lack of convincing enhancement of the splenic vein and heterogenous appearance of the spleen were suspicious for early splenic ischaemia. Laparotomy revealed an engorged twisted spleen around its pedicles. The spleen was identified in the pelvis with a torted vascular pedicle, which was subsequently detorted and manipulated back into the left upper quadrant (LUQ), with a pre-peritoneal space formed in the LUQ, the spleen was inserted into this pocket.","PeriodicalId":429686,"journal":{"name":"EAS Journal of Radiology and Imaging Technology","volume":"48 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140498338","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, they come at the cost of harming the patients and health workers through unnecessary high exposure to radiation particles. Aim: The study aimed to evaluate and compare the effectiveness and the radiation doses of the recent Philips imaging systems Azurion Hybrid OR and the older Philips systems Allura Xper FD 10 and Allura clarity FD 10 in the cardiac catheterization laboratories. Method: A descriptive, comparative research design was utilized, 480 procedures were assessed retrospectively, and all met predetermined inclusion criteria from January 2014 until May 2023. Dose area product, Air Kerma, and Fluoroscopy time (Fluro time) were compared between the three Philips systems, which are Allura Xper FD10/10 R 7.2 and Allura Clarity FD10 R8.2 (old system) and Hybrid Azurion new Philips system. Result: Allura clarity FD 10 and Azurion Hybrid OR were superior to Allura Xper FD 10 in Dose Area Product and Air Kerma (p<0.5). However, fluro time was statistically non-significant among the systems. Conclusion: The latest X-ray imaging systems significantly manage Dose Area Product and Air Kerma levels during medical procedures. Employing these advanced technologies in a cardiac catheterization lab can yield optimal outcomes while minimizing radiation exposure for patients and healthcare personnel.","PeriodicalId":429686,"journal":{"name":"EAS Journal of Radiology and Imaging Technology","volume":"21 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139247617","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}

Whereas for computed tomography (CT) examinations, DRLs are defined in terms of two established technical parameters namely, Volume-based Computed Tomography Dose Index (CTDIvol) and Dose Length Product (DLP), a debate has ensued as to whether patient size, age and weight or clinical indication should be used as patient parameters. The objective of diagnostic reference levels (DRLs) is to assist in the optimisation of radiation dose to the patients while maintaining diagnostic image quality. It is generally accepted that each country requires having national DRLs to guide the practice of radiography regarding dose optimization as a prerequisite to good radiation protection practice. Objective: This review aimed to establish commonly used approaches to establishing national diagnostic reference levels for computed tomography. Methods: A systematic literature search in databases containing leading journals in radiography, radiology and medical physics was performed aided by the use of carefully selected search terms that relate to CT and DRLs. The literature search was achieved by the use of the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) flow chart. A total of 109 studies were screened out of which 54 were excluded and 55 sought for retrieval. After further assessment for quality, 20 studies were included in this study for review. Key Findings: 95% of the studies in this review used CTDIvol and DLP as technical parameters indicating dose. 70% of the studies reviewed used patient size, age and weight while 30% used clinical indication as patient parameters. 30% of the reviewed articles did indicate that the surveys to establish NDRLs employed a retrospective approach, while 35% employed a prospective approach and 35% did ..","PeriodicalId":429686,"journal":{"name":"EAS Journal of Radiology and Imaging Technology","volume":"61 2-3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139268516","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}

Ultrasound can be a useful tool for early diagnosis of breast cancer based on the breast lesions’ features. However, an overlap in the ultrasound features of malignant and benign breast tumours has been noticed together with a paucity of information on the ultrasound features that are more suggestive of breast cancer. Objective: The purpose of this study was to identify ultrasound features of suspected breast cancer lesions which may assist in ascertaining a high breast cancer or benign breast disease suspicion index, that may be used to prioritise patients requiring further and urgent management for breast cancer. Methods: Systematic random sampling was used for the selection of participants in this study. The selected patients first underwent an ultrasound scan in the Ultrasound department to obtain the breast lesion ultrasound features. The histology results for the same patients were then obtained from the University Teaching Hospital (UTH) histology laboratory or the histology report filed in the patient’s medical file. Results: Irregular shape of breast lesions, vertical orientation of breast lesions, hypoechogenicity of breast lesions, complex echo pattern of breast lesions, irregular or spiculated margin contours of breast lesions, compression of breast lesion surrounding tissue, absence of hyperechogenic spots in breast lesions and a breast lesion boundary with neither a hyperechoic halo nor thin capsule (None) were found to be associated with breast cancer. No breast lesion showed less than 3 ultrasound features suspicious for breast cancer. Hyperechoic spots in breast lesions were found to be associated with non-cancerous breast lesions.

It most commonly results from orbital trauma in over fifty percent (50%) of cases, and majority are unilateral. However, traumatic bilateral ectopia lentis is rare. Hereditary connective tissue diseases may also cause ectopia lentis (usually bilateral). The role of imaging is very crucial in early identification of ocular pathologies following trauma. Ocular sonography, being the cheaper, safer and very readily available modality in most low and middle income countries, becomes handy in the initial imaging work-up of patients with ocular trauma. Objectives: To report a rare case of traumatic bilateral cataractous ectopia lentis in an elderly female patient. To review pertinent literature about this condition. To justify the role of various imaging modalities, and particularly highlight the usefulness of ultrasound for evaluating cases of ocular trauma especially in emergency situations. Case Report: The case of a 75-year old female who had blunt trauma to her eyes, and never sought immediate specialized medical care, but instead chose to patronise a traditional healing home. Her visual impairment gradually deteriorated, necessitating a late presentation for imaging at our private radiodiagnostic facility in Agbor, Nigeria. Imaging using ocular sonography, revealed bilateral displaced cataractous lenses with associated vitreous haemorrhage, necessitating an immediate, but a late referral for specialized care. Conclusion: Emergency ocular sonogram is of utmost importance in cases of acute ocular trauma, as it can help identify ocular pathologies promptly.","PeriodicalId":429686,"journal":{"name":"EAS Journal of Radiology and Imaging Technology","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126350438","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}

Artificial intelligence (AI) has the potential to allow for more accurate tumour classification and, thus, avoid unnecessary biopsies. Additionally, earlier diagnosis opens up the potential for curative therapies and improves patient outcomes. A number of artificial intelligence models, including machine learning, convolutional neural networks and radiomics-based models have been tested on ultrasound, CT and MRI images of liver lesions.
