to measure the clinical impact of contrast-enhanced ultrasound (CEUS) in the diagnosis of -community-acquired pneumonia (CAP), compared to clinical, radiological and ultrasound diagnosis.
84 patients (47/37 males/females, mean age:78,57±11,7 Y) with clinical suspicion of pneumonia and with ultrasound findings of peripheral lung lesions, were investigated with CEUS for a better characterization. Final diagnosis of 65 cap was obtained with complete disappearance of symptoms and pulmonary nodule(s); 19 neoplasms: 16 patients performed histologically with bronchoscopy; 3 refused (non-invasive diagnosis with basal CT-scan and positron emission tomography (PET) with fluorodeoxyglucose (FDG)). Sensitivity, specificity, overall diagnostic accuracy (ODA) (and corresponding AUROC) of clinical-data (CD), chest X-ray(CXR), Lung-ultrasound(LUS), CEUS were calculated with SPSS 26.0 software.
Final diagnosis: 65 CAP, and 19 chest cancers. 9/65 (13%) patients died, of these 7/9 with older age and heart disease as comorbidity. CD: True-Positive (TP):23, True-negative (TN): 17; False-Positive (FP):2; False-negative (FN):42 (sens:35,4% spec:89,5% ODA10%: PPV:92%, NPV:28,8%) (AUROC±SEauc:0,46±0,076); CXR: TP: 36, TN:14; FP:5, FN:29; (sens: 55,4%; spec: 73,7%; ODA: 32%; PPV:87,5%, NPV:32,66%) (AUROC±SEauc:0,645±0,068). US: TP:59; TN: 14; FP:5, FN:6 (sens: 90,8%, spec: 73,7%, ODA: 84,9%, PPV:92,2%, NPV:70%) (AUROC±SEauc:0,9417±0,024); CEUS: TP: 63; TN: 19; FP:0; FN:2 (sens: 96,9%; spec: 100% ODA: 97,5%; PPV: 100%, NPV:90,5%) (AUROC±SEauc:0,98±0,01).
Clinical-data and chest X-RAYS are insufficient to obtain a correct diagnosis of CAP in elderly population; US demonstrated a good accuracy to establish CAP, but with a relatively low specificity; in these cases, CEUS is able to give a correct characterization, allowing you to save the need for a chest contrast-enhanced-CT (CECT).
与临床、放射学及超声诊断相比，评估超声造影（CEUS）在社区获得性肺炎（CAP）诊断中的临床影响。
84例临床怀疑肺炎且超声发现外周肺病变的患者（47例男性/37例女性，平均年龄：78.57±11.7岁）接受CEUS检查以进行更好的特征描述。65例CAP通过症状和肺结节完全消失获得最终诊断；19例为肿瘤：16例患者通过支气管镜进行组织学检查；3例拒绝（通过基础CT扫描和氟脱氧葡萄糖（FDG）正电子发射断层扫描（PET）进行非侵入性诊断）。使用SPSS 26.0软件计算临床数据（CD）、胸部X线（CXR）、肺部超声（LUS）、CEUS的敏感性、特异性、总体诊断准确性（ODA）（及相应的受试者工作特征曲线下面积（AUROC））。
最终诊断：65例CAP，19例胸段癌症。65例中有9例（13%）患者死亡，其中7/9例年龄较大且合并心脏病。CD：真阳性（TP）：23，真阴性（TN）：17；假阳性（FP）：2；假阴性（FN）：42（敏感性：35.4%，特异性：89.5%，ODA：10%：阳性预测值：92%，阴性预测值：28.8%）（AUROC±标准误：0.46±0.076）；CXR：TP：36，TN：14；FP：5，FN：29；（敏感性：55.4%；特异性：73.7%；ODA：32%；阳性预测值：87.5%，阴性预测值：32.66%）（AUROC±标准误：0.645±0.068）。超声：TP：59；TN：14；FP：5，FN：6（敏感性：90.8%，特异性：73.7%，ODA：84.9%，阳性预测值：92.2%，阴性预测值：70%）（AUROC±标准误：0.9417±0.024）；CEUS：TP：63；TN：19；FP：0；FN：2（敏感性：96.9%；特异性：100%，ODA：97.5%；阳性预测值：100%，阴性预测值：90.5%）（AUROC±标准误：0.98±0.01）。
临床数据和胸部X线不足以在老年人群中正确诊断CAP；超声在诊断CAP方面显示出良好的准确性，但特异性相对较低；在这些情况下，CEUS能够给出正确的特征描述，无需进行胸部增强CT（CECT）检查。
