Regions of interest were marked on sagittal T2-weighted fat-suppressed lumbar MRI scans. Radiomic features were extracted and used to build a radiomics model. The significance of these features was evaluated using the Shapley Additive Explanations (SHAP) method. Intravoxel incoherent motion (IVIM) quantitative parameters were also included as clinical features, with key parameters selected to create a clinical model. A nomogram model was developed by combining clinical and radiomic features. The performance of the three models was compared and validated using receiver operating characteristic curves, calibration curves, and decision curves.ResultsEight radiomic features were selected. The clinical feature's D-value showed significant differences between the training and test sets. The nomogram model integrating both clinical and radiomic features achieved an AUC of 0.998 in the training set and 0.992 in the test set, surpassing the performance of both the clinical and radiomic models alone. Calibration and decision curves confirmed the model's strong predictive performance.ConclusionThis study shows that the MRI-based radiomics nomogram model effectively differentiates between early and advanced Brucella spondylitis, offering clinicians a valuable tool for personalized treatment across different disease stages.","PeriodicalId":7143,"journal":{"name":"Acta radiologica","volume":" ","pages":"2841851251331726"},"PeriodicalIF":1.1,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143951851","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}

The technique of T1-mapping investigates interstitial fibrosis. The most used method for myocardial T1-mapping is the modified Look-Locker Inversion recovery sequence (MOLLI) using balanced steady-state free precession (SSFP). However, SSFP is susceptible to off-resonance artifacts, leading to errors. Gradient echo (GRE) sequences are less prone to these artifacts.PurposeTo investigate whether T1-mapping using GRE was comparable to SSFP in this population.Material and MethodsPre/post-contrast T1-mapping was performed on 16 devices utilizing MOLLI with SSFP and GRE strategies at 1.5 T, as well as 10 non-device controls. The difference in mean T1 time by SSFP versus GRE (both pre- and post-contrast for each slice) for device patients was analyzed.ResultsNative T1 for the device cohort was 1053 ± 94 ms for SSFP and 969 ± 83 ms for GRE. GRE T1 measurements were shorter than SSFP measurements (difference over all slices for SSFP vs. GRE pre-/post-contrast were 74 ms and 27 ms). Mean λ for GRE (devices) was 0.520 ± 0.194 (p = 0.30). λ for SSFP (devices) was 0.536 ± 0.124 (P = 0.08). There was no difference in λ between SSFP versus GRE in device patients (P = 0.91). The percentage of segments identified as artifact on T1 maps for device patients was 24% and 45% for GRE and SSFP, respectively.ConclusionCompared to SSFP, T1 values using GRE were consistently shorter, while λ values remained equivalent. There was less visual artifact on GRE images, suggesting advantageous utility over SSFP in patients with cardiac devices.","PeriodicalId":7143,"journal":{"name":"Acta radiologica","volume":" ","pages":"2841851251332461"},"PeriodicalIF":1.1,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143959618","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}

Before whole-spine weight-bearing CT is used in clinical practice, potential errors must be addressed, such as the need to stitch multiple volumes due to the field-of-view limitations of CBCT technology.PurposeTo determine the geometric error of fused CBCT images of the spine using automatic stitching software.Material and MethodsIn total, 144 CBCT scans were obtained using three human cadavers. The geometric stitching error was determined in terms of total translation and rotation between vertebrae Th12 and L5, which were positioned in separate image volumes, with a regular spiral CT scan as a reference. The effect of cadaver size, radiation dose, and volume overlap between adjacent CBCT images on the stitching error was determined using Spearman's rank correlation test.ResultsThe median total translation and rotation error were 1.88 mm (interquartile range [IQR] = 1.48-2.42 mm) and 0.54° (IQR = 0.35°-0.63°), respectively. A weak negative correlation between the different volumes of overlap and total translation (r = -0.396; P < 0.001) and rotation (r = -0.319; P < 0.001) was found, as well as a weak positive correlation between the cadaver size and total translation (r = 0.456; P < 0.001).ConclusionThe results of this cadaver study showed stitching errors in the order of 2 mm for translation and 0.5° for rotation in fused CBCT volumes of the spine.

Patients in the four groups were routinely treated with medicine, on this basis: group B received NMES treatment; group C received modern rehabilitation technology treatment; and group D was treated with NMES and modern rehabilitation technology. Rehabilitation effect, cerebral hemodynamic indices, neurological function recovery, Fugl-Meyer Assessment (FMA) and Motor Assessment Scale (MAS) scores, self-care, and quality of life were compared.ResultsAfter treatment, the total effective rate of group D was 96% higher than that of group A (64%), group B (82%), and group C (84%). Bilateral middle cerebral artery Vm and Vs and scores of FMA, MAS, functional independence measure, and modified Barthel index increased; RI and NHISS scores decreased; and all group D improved significantly versus groups A, B, and C, and both groups B and C improved significantly versus group A.ConclusionNMES with modern rehabilitation technologies synergistically treat motor dysfunction after AIS with ideal rehabilitation effect, improving cerebral hemodynamics, neurological and limb motor function recovery, and self-care ability and quality of life.","PeriodicalId":7143,"journal":{"name":"Acta radiologica","volume":" ","pages":"401-409"},"PeriodicalIF":1.1,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142998334","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}
