An intra-individual comparison of image quality and radiation dose was carried out. Three blinded radiologists rated overall image quality, image sharpness, and image noise using a 5-point Likert scale. The study measured the dose length product, the volumetric CT dose index, the effective dose, and the signal to noise ratio (SNR).ResultsThe cohort comprised 23 individuals (6 women [26%], 17 men [74%]; mean age = 36.7 years). PCCT achieved superior evaluations for image quality in comparison to EID-CT (mean = 5 vs. 3; P <0.001). Furthermore, PCCT exhibited diminished image noise (mean = 4 vs. 3; P <0.001). The mean SNR of the paranasal sinuses demonstrated an increase in PCCT as opposed to EID-CT (P <0.001).

AVM types were classified according to the Cho-Do angiographic classification. Cardiomegaly was defined as a cardiothoracic ratio (CTR) >0.5 on chest radiographs. Factors associated with cardiomegaly and post-treatment changes in CTR and cardiac function were analyzed.ResultsCardiomegaly was observed in 108/437 (24.7%) patients. Multivariate analysis identified type I/II (vs. III) (P = 0.002), lesion diameter >10 cm (P = 0.013), and bone involvement (P = 0.021) as significant risk factors. Abdominopelvic (P <0.001) and thoracic-neck AVMs (P = 0.018) had higher cardiomegaly prevalence than extremity AVMs. Among the 108 patients with cardiomegaly, 84 underwent follow-up chest radiographs. The median CTR reduction rate was 8.9% (interquartile range [IQR] 4.1-15.8), with a significant decrease (P <0.001). Higher angiographic devascularization was associated with greater CTR reductions (P = 0.013). Echocardiography was selectively performed in patients with suspected cardiac involvement. Among 27 patients with both pre- and post-treatment echocardiography, 44% showed functional improvement.ConclusionAVM type, extent, location, and bone involvement were significant factors influencing cardiomegaly risk.

A dynamic enhanced scan defined urinary obstruction. Stone size was the largest diameter of three multiplanar reformatations (axial, coronal, sagittal). Stone location was registered as proximal, mid-ureter or distal. Symptoms were registered in standardized questionnaires by the patient at the time of the follow-up.ResultsIn total, 43/81 (53%) patients reported symptoms. Obstruction of any degree was present in 16 (20%) patients. In 7 (100%) patients with moderate-severe obstruction reported discomfort attributed to the stone.

Ten Japanese white rabbits were divided equally into two groups (0.6-W and 1.1-W) based on electric power settings. Ablation was performed in three liver regions for each rabbit. Ablated areas were measured using fat-suppressed T1-weighted imaging following gadolinium administration and histological examination with hematoxylin and eosin staining. For the intrahepatic portal vein ablation, nine rabbits were assigned to the ablation group and eight rabbits served as controls. Portography was conducted before and after the procedure.ResultsIn vitro, temperature increases at ablation site and at 5-, 10-, and 15-mm distances and ellipsoid-shaped ablated area were proportional to electric power. In the in vivo experiment, the 1.1-W group exhibited significantly greater ablation effects compared to the 0.6-W group, as measured by magnetic resonance imaging (50.6 vs. 22.7 mm²; P <0.001) and histopathology (38.9 vs. 21.7 mm²; P = 0.001). Nearly complete occlusion (>80% stenosis) was more frequently observed in the ablation group (72.2% vs. 22.2%; P = 0.007).ConclusionThe thermal ablation device utilizing a nitinol coil demonstrated effective liver ablation.

Non-invasive imaging biomarkers that reflect tumor angiogenesis and vascular maturity may help predict LNM.PurposeTo determine whether the magnetic resonance imaging (MRI) quantitative parameters combined with microvascular characteristics predict the potential of LNM by reflecting angiogenesis or vascular maturation in CSCC.Material and MethodsThe clinicopathological characteristics, microvascular characteristics and MRI quantitative parameters of the LNM group (43 cases) and the non-LNM group (42 cases) were analyzed. The correlation between microvascular and MRI quantitative parameters and the ability of combined diagnosis of LNM were analyzed.ResultsThere were significant differences in the FIGO stage and the short diameter of the largest lymph node between patients with or without LNM. There was no significant difference in the apparent diffusion coefficient (ADC) value of the primary tumor between the LNM group and the non-LNM group (P >0.05). Spearman's correlation analysis showed that there was no correlation between ADC and MVD or microvessel pericyte coverage index (MPI) (all P >0.05). Ktrans and Kep were significantly higher, and MPI was significantly lower in patients with LNM. There were negative correlations between Ktrans and MPI, and Kep and MPI. Binary logistic regression analysis showed that a combined prediction model constructed by Ktrans, Kep, and MPI had the highest diagnostic efficacy.ConclusionKtrans and Kep of CSCC can predict LNM by non-invasively reflecting the maturity of tumor vessels, and the combined Ktrans, Kep, and MPI have promising diagnostic efficiency for LNM.","PeriodicalId":7143,"journal":{"name":"Acta radiologica","volume":" ","pages":"188-198"},"PeriodicalIF":1.1,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145706963","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
