Employing a multi-faceted review, we analyzed digital platforms, academic databases, and social media for resources beneficial to medical students in radiology, assessing their accessibility, content quality, and educational value. Our investigation uncovered a broad spectrum of resources, from foundational platforms to advanced simulation tools, varying in their approach to teaching radiology. Traditional resources provide essential theoretical knowledge, while digital tools, including interactive case studies and multimedia content, offer immersive learning experiences. Notably, resources integrating machine learning and social media facilitate dynamic, peer-to-peer learning and up-to-date case discussions. Despite the minimal current focus on VR, its role in enhancing interactive learning is notable. The diversity in educational tools highlights the evolving nature of radiology education, reflecting a shift towards more engaging and practical learning methodologies. Identifying and integrating a variety of educational resources into radiology education can significantly enhance learning outcomes for medical students, preparing them for the complexities of modern diagnostic radiology with a well-rounded educational approach.","PeriodicalId":94174,"journal":{"name":"Polish journal of radiology","volume":"89 ","pages":"e508-e516"},"PeriodicalIF":0.0,"publicationDate":"2024-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11538907/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142592344","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Of these 10 patients, 9 developed chylous ascites after liver surgery, and 1 after a radical gastrectomy.Results: Lymphangiography was successfully performed in all 10 patients. The average dosage of lipiodol used was 4.5 ml (range 3.5-7.0 ml). No procedure-related complications were observed after excluding unrelated factors. During lymphangiography, lipiodol leakage was directly observed in 3 cases, and in the other 5 cases, it was detected through abdominal computed tomography post-lymphangiography.

The standard treatment is surgical resection followed by radiotherapy and chemotherapy. Despite optimal treatment methods, the prognosis for patients remains poor. Preoperative determination of glioblastoma margins remains beneficial for the complete removal of the tumor mass. Radiotherapy is essential for post-surgery treatment, but radioresistance is a significant challenge contributing to high mortality rates. Advanced imaging technologies are used to analyze the changes in the peritumoral brain zone (PTZ). Consequently, they may lead to the development of novel therapeutic options, especially targeting the marginal parts of a tumor, which could improve the prognosis of glioblastoma patients. The clinical presentation of glioblastoma is heterogeneous and mostly depends on the location and size of a tumor. Glioblastomas are characterized by both intratumoral cellular heterogeneity and an extensive, diffuse infiltration into the normal tissue bordering a tumor called the PTZ. Neuroimaging techniques, such as diffusion-weighted imaging (DWI), diffusion tensor imaging (DTI), perfusion-weighted imaging (PWI), proton magnetic resonance spectroscopy (1H MRS), and chemical exchange saturation transfer (CEST) are useful methods in the evaluation of the tumor infiltration and thus the resection margin.","PeriodicalId":94174,"journal":{"name":"Polish journal of radiology","volume":"89 ","pages":"e480-e487"},"PeriodicalIF":0.0,"publicationDate":"2024-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11538905/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142592350","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Computed tomography (CT) served as the diagnostic benchmark, compared with CEUS and B-mode ultrasound (B-mode). Two radiologists assessed the presence, size, and characteristics of the HA.Results: The contrast enhancement pattern on CEUS matched post-contrast CT. Lesion size detected by CEUS ranged from 1.16 cm to 15.33 cm (median 5.74 cm). CT classified lesions into four types: I (tumor-like) - 2, II (honeycomb) - 5, III (lacunar) - 23, IV (cystic-like) - 34. CEUS fully agreed with these classifications. B-mode missed two type I lesions. For type III abscesses, agreement with CEUS was perfect (κ = 1, 100%), and moderate with B-mode (κ = 0.50, 79.7%). For type IV abscesses, agreement with CEUS was perfect (κ = 1, 100%), and high with B-mode (κ = 0.88, 93.75%). Pus enhancement remained stable (± 15 dB), while the abscess pouch background varied (± 11 dB to ± 6 dB). The Mann-Whitney U test confirmed these observations (arterial: p = 1.02e-14, portal: p = 3.79e-12, late venous: p = 4.53e-13). No significant difference in enhancement values was found based on abscess size (> 4 cm vs. < 4 cm).Conclusions: CEUS is superior to B-mode for diagnosing and monitoring HA, offering clearer views of the abscess pouch, septa, and liver parenchyma. The purulent part lacks contrast, allowing accurate assessment. CEUS can replace CT for monitoring and aid in patient selection for percutaneous intervention.","PeriodicalId":94174,"journal":{"name":"Polish journal of radiology","volume":"89 ","pages":"e470-e479"},"PeriodicalIF":0.0,"publicationDate":"2024-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11538908/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142592346","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Thyroid Imaging Reporting & Data System (TIRADS) aims to standardise assessment and reduce fine-needle aspiration biopsies through risk stratification. This pilot study examined knowledge and utilisation of TIRADS among Polish physicians, their perception of the usefulness of TIRADS application and the extent of knowledge of individual nodule features included.Material and methods: An internet-based questionnaire about TIRADS use in clinical practice was sent out to Polish Ultrasound Society members. Information on the responder's experience with thyroid ultrasound and knowledge and use of TIRADS was assessed and analysed.Results: Out of 159 physicians, 66.6% did not use TIRADS despite 43.4% being aware of its existence. EU-TIRADS was the most commonly adopted classification (50.9%). Participants who adopted TIRADS were younger (p = 0.047) and more likely to be radiologists (p < 0.01).

Reducing the scanning time has become a critical area of focus in MRI, aiming to enhance patient comfort, reduce motion artifacts, and increase MRI throughput. In the past 5 years, artificial intelligence (AI)-based algorithms, particularly deep learning models, have been developed to reconstruct high-resolution images from significantly fewer data points. These new techniques significantly enhance MRI efficiency, improve patient comfort and lower patient motion artifacts. Improving MRI throughput with lower scanning duration increases accessibility, potentially reducing the need for additional MRI machines and associated costs. Several fields can benefit from shortened protocols, especially for routine exams. In oncologic imaging, faster MRI scans can facilitate more regular monitoring of cancer patients. In patients suffering from neurological disorders, rapid brain imaging can aid in the quick assessment of conditions like stroke, multiple sclerosis, and epilepsy, improving patient outcomes. In chronic inflammatory disease, faster imaging may help in reducing the interval between imaging to better check therapy outcomes. Additionally, reducing scanning time could effectively help MRI to play a role in emergency medicine and acute conditions such as trauma or acute ischaemic stroke. The purpose of this paper is to describe and discuss the advantages and disadvantages of introducing deep learning reconstruction techniques to reduce MRI scanning times in clinical practice.","PeriodicalId":94174,"journal":{"name":"Polish journal of radiology","volume":"89 ","pages":"e443-e451"},"PeriodicalIF":0.0,"publicationDate":"2024-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11497590/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142515580","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
