Sixty-six enhanced foot MRIs with reduced dose gadobutrol (0.07 mmol/kg) and 66 MRIs with standard dose gadoterate (0.1 mmol/kg) were reviewed by two radiologists. For the primary study objective, two parameters (lesion border visualization and subjective lesion enhancement) for qualitative lesion visualization were assessed between the two agents using a noninferiority analysis. In the quantitative assessment of lesion enhancement, lesion-to-background ratio and enhancement percentage were compared between the two agents.ResultsThe mean scores for lesion border delineation and the visual degree of contrast enhancement were nearly identical between the two groups. For both readers, the lower limit of the 95% confidence interval (CI) for the difference did not drop below -0.35, which is above the noninferiority margin. Regarding quantitative analysis, no significant differences were observed in the enhancement percentage and lesion-to-background ratio between the two agents (p > 0.5).ConclusionA 30% reduced dose of gadobutrol (0.07 mmol/kg) is as effective as the standard gadoterate dose (0.1 mmol/kg) for lesion visualization in contrast-enhanced MRI of diabetic foot osteomyelitis, with similar enhancement efficacy.","PeriodicalId":7143,"journal":{"name":"Acta radiologica","volume":" ","pages":"2841851251330281"},"PeriodicalIF":1.1,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143690797","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}

However, this method can be misleading because of random threshold selections, overlooking post-contrast creatinine decreases, and discarding continuous renal function data. The main impact of contrast on renal function can be revealed by analyzing the mean changes in SCr and evaluating their significance.PurposeTo analyze published data permitting calculation of mean SCr changes after intravenous contrast.Material and MethodsWe identified publications including patients with pre-existing renal dysfunction who received modern contrast agents, specified contrast type and dose, and means and standard deviations of SCr measurements before and after contrast.ResultsIn 14 articles, including 2057 patients, mean SCr pre-contrast was 148.6 µmol/L (1.68 mg/dL); decreasing significantly to 144.1 µmol/L (1.63 mg/dL) after contrast. Significant diminutions occurred at post-contrast intervals of 4, 7, and 10 days, and in patients who received hydration therapy. Of the patients, 6.6% met the specific thresholds for contrast nephropathy as defined by individual studies.ConclusionThe slight significant improvement in SCr after iodinated contrast suggests that some prior estimates of the risk of contrast-induced acute kidney injury (AKI) have been erroneously high and corroborates the current view that the risk of clinically important AKI after contrast is unlikely in patients with moderate renal failure. Threshold-based investigations of nephropathy may be misleading. Mean post-contrast SCr decline should be considered for clinical decisions regarding contrast administration. Future studies on the renal effects of contrast should analyze means, variation, and significance of post-contrast SCr changes.","PeriodicalId":7143,"journal":{"name":"Acta radiologica","volume":" ","pages":"2841851251327895"},"PeriodicalIF":1.1,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143668826","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}

Findings were analyzed in terms of demographic characteristics of patients' and procedure-related features.ResultsThe mean age of the patients was 65 ± 9.7 years and mean lesion size was 34.31 ± 16.99 mm. Pneumothorax developed in 176 patients. The frequency and severity of pneumothorax were higher in male patients (P < 0.001 and P = 0.003). Emphysema was a risk factor for pneumothorax (P = 0.002). The rate of pneumothorax was higher in lower lobe lesions. Pleural length made a significant difference, especially for the severity of pneumothorax. The severity of pneumothorax increased as dwell time increased (P = 0.029). The need for a chest tube was significantly higher in the group with pneumothorax thickness >1 cm (P < 0.001). The requirement for multiple passes increased the risk of developing pneumothorax (P < 0.001). Procedure-related hemorrhage reduced the risk of pneumothorax and prevented the progression of pneumothorax (P < 0.001 for both). The risk of developing pneumothorax was lowest in the supine position (P = 0.001).ConclusionPatient's sex, presence of emphysema, and lesion location are unchangeable patient-dependent factors for the development of pneumothorax.

Concordance between skin testing and DPT was 85.7% (6/7) for iohexol, 65.1% (28/43) for iodixanol, and 100% (2/2) for iopromide. Cross-reactivity was in the range of 59.6%-75.9% between iohexol and iodixanol, 75.0%-77.4% between iohexol and iopromide, and 43.3%-60.0% between iodixanol and iopromide. Only 1/14 patients who were skin test and DPT negative developed a reaction on re-exposure to ICM after testing.ConclusionObjective testing for ICM hypersensitivity, particularly within 6 months of initial exposure, allows the majority of patients to be administered the same or an alternative ICM with no adverse reaction, with iodixanol having the lowest cross-reactivity.","PeriodicalId":7143,"journal":{"name":"Acta radiologica","volume":" ","pages":"2841851251321476"},"PeriodicalIF":1.1,"publicationDate":"2025-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143622947","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}
