Consequently, improved intraoperative imaging could reduce the need for follow-up computed tomography (CT) examinations and reinterventions.PurposeTo assess the feasibility of performing intraoperative CT angiography (CTA) during f-bEVAR, and to compare intraoperative CTA findings with postoperative CTA.Material and MethodsIntraoperative catheter-CTA (cCTA) with intra-arterial administration of diluted contrast medium was performed in 31 patients undergoing f-bEVAR. Intraoperative cCTA findings were compared with postoperative CTA on day 1 in 28 patients. Discrepancies in findings between the two CTA, any adjunctive corrective maneuvers, time required for cCTA imaging, radiation dose exposure, and reintervention rates were recorded.ResultsIntraoperative cCTA was technically successful in all patients (100%). Immediate corrective maneuvers were performed in 2 (7%) patients based on cCTA findings. Discrepancies between intraoperative and postoperative CTA were observed in 4/28 (14%) patients, all related to early-phase endoleaks. No discrepancies were found regarding endograft positioning or procedural complications. Mean effective dose from intraoperative cCTA was 11.3 mSv (interquartile range = 8.0-12.8).ConclusionIntraoperative cCTA during f-bEVAR was feasible and achieved a high technical success rate. It provided reliable visualization of endograft architecture and intraprocedural complications, but cCTA did not identify the same number of early-phase endoleaks as postoperative CTA. While the routine use of intraoperative cCTA may offer limited patient benefit, it can be a useful adjunct in challenging cases.","PeriodicalId":7143,"journal":{"name":"Acta radiologica","volume":" ","pages":"2841851251381345"},"PeriodicalIF":1.1,"publicationDate":"2025-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145297971","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}

Patients with endoscopically active CD completed ileocolonoscopy and MRI with intravenous contrast and diffusion-weighted sequences before and after medical treatment. Response was defined as ≥50% reduction of the Simple Endoscopic Score for Crohn's Disease. Changes in bowel wall thickness (BWT) and apparent diffusion coefficient (ADC) were compared to the magnetic resonance index of activity (MaRIA), simplified MaRIA, and Clermont score.ResultsA total of 42 patients entered the analysis, and endoscopic response was achieved in 19 (45.2%). All activity scores improved in patients with endoscopic response compared to non-responders (P <0.05). The relative reduction of BWT for the most severely affected bowel segment (area under the curve [AUC]=0.76, 95% confidence interval [CI]=0.61-0.91) trended towards a higher diagnostic accuracy compared to the global MaRIA score (AUC=0.63, 95% CI=0.45-0.81; P = 0.1). The per-segment response was more accurately evaluated with BWT compared to the segmental MaRIA score (AUC=0.82 and 0.67, respectively; P = 0.05).

Student t-test, Mann-Whitney U test, ANOVA, and Kruskal Wallis test were used to compare the means between groups. Pearson's correlation test was used for correlation analysis.

A total of 213 patients were classified into normal (n = 72), osteopenia (n = 82), and osteoporosis (n = 59) groups based on their DXA T-scores. T1-weighted MRI images were used to measure vertebral body signal intensity (SI) and cerebrospinal fluid (CSF) SI, which were then used to calculate VBQ scores. Both cervical and lumbar VBQ scores were compared to DXA results to evaluate diagnostic efficacy.ResultsCervical VBQ scores, particularly the C4:posterior fossa CSF SI ratio, demonstrated significant correlations with DXA T-scores (P = 1.7 × 10-5). The study found that the C4:posterior fossa CSF SI ratio had a high diagnostic accuracy (AUC = 0.81) for distinguishing between normal bone density and osteopenia/osteoporosis.

We measured the mean signal intensity of the meniscus from the in-phase (IP) and OP mDixon images with sagittal reconstruction. The proportional decrease of signal intensity (signal drop) was calculated. The median value with 25th (Q1) and 75th (Q3) percentiles of signal drop was reported for each meniscus. The Mann-Whitney U-test was used to compare the signal drop between meniscal tear and normal groups.ResultsIn the lateral meniscus (LM) and medial meniscus posterior horn (MMPH) tear groups, the median values of signal drop were significantly lower than in the normal group (P <0.05). Although the MM anterior horn (MMAH) tear group had a lower median signal drop than the normal group, there was no significant difference (P = 0.116 and 0.283, readers 1 and 2, respectively).ConclusionThe signal drop in torn menisci was lower than in normal menisci across all tear types, with statistical significance observed in LM and MMPH tears. We believe that these results may be explained by a reduced intracellular lipid content in torn menisci compared to normal menisci.","PeriodicalId":7143,"journal":{"name":"Acta radiologica","volume":" ","pages":"1110-1116"},"PeriodicalIF":1.1,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144265041","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}
