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. However, the aim should be to plan the process correctly and complete it with a single entry and a short dwell time.","PeriodicalId":7143,"journal":{"name":"Acta radiologica","volume":" ","pages":"666-674"},"PeriodicalIF":1.1,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143655556","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}

Enhancing lesions detected on CT showing correlation with additional suspicious lesions detected on MRI were recorded as CT-correlated enhancements. The pathological findings were confirmed by subsequent percutaneous biopsy or lesion excision. The clinical and MRI features of additional suspicious lesions were compared according to the standard reference or the presence of CT-correlated enhancement.ResultsThere were 96 (39.2%) additional suspicious lesions detected on preoperative breast MRI and a malignancy rate of 39.6%. Of 96 lesions, chest CT revealed correlated enhancement in 64 (66.7%) lesions, including 33 malignant lesions. Among the 32 lesions that showed no correlation enhancement on chest CT, 5 (15.6%) were malignant.
