All patients underwent preoperative MRI with the DWI non-EPI sequence. Data from surgical protocols, medical histories, outpatient records, and imaging results were analysed. MRI scans were reviewed by experienced radiologists and otosurgeons. The study was approved by the local Bioethics Committee.Results: Clinical and radiological concordance was found in 80% of patients. True positive results were observed in 77.5% of cases, while true negative results were noted in 2.5%. False positive results occurred in 8% of cases, mainly due to wax in the external auditory canal. False negative results were found in 12% of cases, often due to small or mural cholesteatomas. The sensitivity of MRI DWI non-EPI in detecting cholesteatoma was 87%.Conclusions: MRI DWI non-EPI is an effective tool for detecting cholesteatoma recurrence, potentially avoiding unnecessary second-look surgeries. Awareness of false positive and negative results is crucial, and correlation of MRI findings with clinical examinations is recommended. To minimise false results, ear cleaning before MRI and repeated examinations at intervals are advised.","PeriodicalId":94174,"journal":{"name":"Polish journal of radiology","volume":"90 ","pages":"e318-e323"},"PeriodicalIF":0.0,"publicationDate":"2025-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12243516/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144610704","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}

Our principal aim was to conduct a systematic review of studies that compare the accuracy of dynamic flow measurements of XV in comparison to existing imaging methods. A systematic review was conducted according to PRISMA criteria. Fourteen papers from indexed journals, including ScienceDirect and PubMed, were examined to determine the benefits of XV for capturing dynamic flow patterns. The data show that XV outperforms traditional imaging techniques by providing higher spatial and temporal resolution, allowing for exact tracking of airflow and blood flow dynamics. These enhanced visuals help to improve diagnosis accuracy and comprehension of physiological processes. XV is a significant improvement in medical imaging, providing real-time, high-resolution insights that help with patient evaluation and clinical decision-making.

By employing advanced imaging techniques like 3D T1-weighted, T2-weighted, and fluid-attenuated inversion recovery (FLAIR) sequences, MRI volumetry enables clinicians to objectively quantify brain volume changes associated with neurological conditions such as Alzheimer's disease, multiple sclerosis, epilepsy, and myotonic dystrophy. Automated segmentation tools, including FreeSurfer, NeuroQuant, volBrain, and AccuBrain, facilitate precise and reproducible analysis of structural brain changes, contributing significantly to early diagnosis, patient monitoring, and therapeutic planning. In Alzheimer's disease, volumetric MRI enables the detection of early hippocampal and temporal lobe atrophy, providing a crucial biomarker for diagnosis and monitoring disease progression. Similarly, in multiple sclerosis, volumetric analyses quantify grey and white matter degeneration, reflecting motor and cognitive impairment severity. Moreover, quantitative MRI techniques precisely delineate structural abnormalities like hippocampal sclerosis and focal cortical dysplasia in epilepsy, crucial for accurate surgical intervention. Ongoing advances in artificial intelligence and machine learning are set to further enhance these volumetric approaches, addressing current limitations such as inter-observer variability and expanding their clinical applicability.

The popularisation of imaging techniques that visualise the abdominal cavity, especially ultrasonography (USG), has resulted in an increase in the detection of focal liver lesions (FLL). If the results of other imaging modalities (magnetic resonance imaging [MRI] or computed tomography [CT]) are inconclusive, percutaneous liver biopsy should be considered. Taking into account the limitations of using MRI and CT in liver biopsy, this procedure is mostly performed with ultrasound. It is economical, safe, and swift. Whenever it is impossible to visualise lesions in B-mode (a condition necessary for a safe and effective biopsy), it is advisable to use advanced ultrasound techniques - CEUS or fusion imaging. Limitations of fusion imaging include prolonged time of data processing and difficulties in achieving optimal overlap of images. Conversely, CEUS enhances lesion visualisation but is devoid of the mentioned limitations - it is rapid and requires no additional processing. Furthermore, considering the potential of CEUS in the visualisation of focal liver lesions and differentiation of necrotic areas, accompanied by the ability to detect neuroendocrine tumours or its metastasis, we strongly believe that biopsy procedures - especially core needle biopsies - with CEUS assistance are potent tools in contemporary diagnostics. In this paper we want to share the experience of our centre and review the available literature on performing liver biopsies under CEUS guidance.","PeriodicalId":94174,"journal":{"name":"Polish journal of radiology","volume":"90 ","pages":"e292-e298"},"PeriodicalIF":0.0,"publicationDate":"2025-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12243522/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144610703","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}

Traditionally, surgical resection was the only curative treatment; however, percutaneous ablation (radiofrequency, microwave, and irreversible electroporation) has emerged as a treatment option for select patients. Early trials demonstrated the efficacy of thermal ablation, leading to its inclusion in international guidelines. Currently, for small tumours, it is considered a viable alternative to resection. Recent studies demonstrate the non-inferiority of thermal ablation compared to resection in select cases and emphasize the importance of achieving an adequate ablation margin. Advancements in imaging techniques, ablative modalities, the use of image fusion, as well as ablation confirmation software, allow for a more patient-tailored approach. Additionally, tumour biology, including genetic mutations, influences both overall survival and local control, highlighting the need for personalised treatment strategies. As randomised trials continue to provide more data, the role of ablation in CLM management is evolving. This paper aims to provide a narrative review of factors predicting local control and overall survival in patients treated with ablation. Future research focusing on molecular markers, advanced imaging, and ablation verification techniques may further refine patient selection, and optimise treatment outcomes and follow-up imaging.","PeriodicalId":94174,"journal":{"name":"Polish journal of radiology","volume":"90 ","pages":"e279-e285"},"PeriodicalIF":0.0,"publicationDate":"2025-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12232408/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144586019","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}

Early diagnosis is crucial for effective management and improved outcomes. Computed tomography pulmonary angiography (CTPA), characterised by high sensitivity and specificity, is integral to diagnosing CTEPH by identifying thrombi and associated pulmonary and mediastinal abnormalities. However, radiological features often overlap with other diseases, and their detection depends on radiologist expertise. This study aims to assess the frequency of characteristic radiological features in CTEPH, compare their prevalence with chronic thromboembolic disease (CTED), pulmonary arterial hypertension (PAH), and acute pulmonary embolism (APE), and evaluate their diagnostic predictive value.Material and methods: This retrospective study analysed 115 patients divided into CTEPH (n = 35), CTED (n = 20), PAH (n = 24), and APE (n = 36) groups, matched by age and sex. CTPA scans were reviewed for signs of chronic embolism, pulmonary hypertension, and right heart overload. Sensitivity, specificity, accuracy, and predictive values were assessed using ROC analysis, expressed as the area under the curve (AUC).Results: CTEPH patients exhibited vessel narrowing, intimal irregularities, bands, and webs in all cases (100%), with the highest diagnostic value at the segmental level (AUC = 0.906). Mosaic perfusion and variability in vessel size demonstrated moderate predictive value (AUC = 0.740 and AUC = 0.788, respectively).Conclusions: CTPA is essential for differentiating CTEPH from other pulmonary vascular conditions. While no single feature achieves 100% predictive value, a comprehensive approach integrating vascular, parenchymal, and cardiac findings is critical for accurate diagnosis.","PeriodicalId":94174,"journal":{"name":"Polish journal of radiology","volume":"90 ","pages":"e267-e278"},"PeriodicalIF":0.0,"publicationDate":"2025-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12232410/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144585999","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}

SUVmean was calculated pre- and post-stimulation using technetium-99 m. Radiomic features were extracted from CT images using PyRadiomics, excluding shape-related features due to the impact of metal artifacts. Spearman's correlation coefficients were used to evaluate the relationship between pre/poststimulation SUVmean ratios and radiomic features. Regression models were created for features strongly correlated with SUVmean ratios.Results: The median pre/post SUVmean ratios were 1.30 (1.02-1.57) for Sjögren's syndrome and 2.35 (2.23-3.01) for sialolithiasis. In Sjögren's syndrome, 4 radiomic features correlated strongly with the SUVmean ratio: busyness (r = 0.78, p < 0.01), energy (r = 0.70, p < 0.01), total energy (r = 0.66, p = 0.01), and high grey level emphasis (r = -0.60, p = 0.02). No significant correlations were observed in sialolithiasis.Conclusions: Specific radiomic features in CT images showed strong correlations with SUV ratios in Sjögren's syndrome but not in sialolithiasis.
