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}

Two independent readers (a radiology resident and an attending radiologist) evaluated the radiographs, blinded to CTs.

The resident radiologist showed lower diagnostic accuracy than the attending radiologist, with more false positives in the rigid-spine group. In both groups, unrecognised fractures were more common for the resident radiologist (61.2% in rigid-spine patients and 48.6% in non-rigid-spine patients) compared to the attending radiologist (51.0% and 40.0%, respectively).

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. These findings suggest the potential utility of CT radiomics in evaluating salivary gland function, particularly in Sjögren's syndrome, providing insights into functional assessments without SPECT/CT.","PeriodicalId":94174,"journal":{"name":"Polish journal of radiology","volume":"90 ","pages":"e253-e259"},"PeriodicalIF":0.0,"publicationDate":"2025-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12232401/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144586020","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}

CTA is an appropriate examination method in patients immediately after coil embolisation in whom severe complications, primarily bleeding, are suspected. Still, it is unsuitable for assessing persistent aneurysmal sac perfusion. MRA is a promising noninvasive technique that does not require ionising radiation. Several studies have demonstrated the superiority of MRA over DSA in detecting small aneurysmal sac reperfusion. DUS, while not a standalone method, may supplement MRA in patients at low risk of reintervention.Conclusions: The evidence regarding follow-up imaging methods after SAAs coil embolisation is limited and of low quality.

Long-segment fusion was associated with unstable type B and C fractures. In short-segment fusion, single level type A fractures were most common. Spinal cord injury occurred only in patients with delayed diagnosis.Conclusions: When plain films are used as a first-line diagnostic test for thoracolumbar spine trauma in stable patients without abnormal neurological signs or symptoms, and long-segment spinal ankylosis is observed, thoracolumbar CT should be used for further evaluation.","PeriodicalId":94174,"journal":{"name":"Polish journal of radiology","volume":"90 ","pages":"e215-e223"},"PeriodicalIF":0.0,"publicationDate":"2025-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12232406/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144585997","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}
