“…Computed tomography of the thorax is considered the "gold standard" for the diagnosis of PE (14). In the present study high-end ultrasound was chosen as standard of reference for the diagnosis of pleural effusion, because this approach is free of radiation exposure to the patients (15,16) and, in a recently published survey Xirouchaki et al showed that high-end ultrasound and computed tomography of the thorax reveal highly concordant results for the diagnosis of PE (17), revealing high-end ultrasound as a eligible standard of reference for the diagnosis of PE.…”

Background: Further development established hand-carried ultrasound (HCU) imagers in daily clinical workflow providing several advantages such as fast bedside availability and prompt diagnosis. Purpose: To evaluate the diagnostic yield of a latest generation HCU imager compared to chest radiography (CR) for the detection of pleural effusion (PE) in intensive care patients. Material and Methods: Forty-eight hemithoraces of 24 patients on surgical intensive care units were enrolled in this study. All hemithoraces were evaluated using both HCU and CR. Definite diagnosis of PE was achieved using a high-end ultrasound system as standard of reference. Statistical analysis was performed using 2 Â 2 tables and a McNemar test. A P value of ,0.05 was considered statistically significant. Results: PE was present in 35 of 48 hemithoraces (73%). The HCU examination was carried out technically successfully in all hemithoraces. Sensitivity and specificity of HCU for the diagnosis of PE was 91% and 100%, respectively, whereas sensitivity and specificity of CR was 74% and 31%, respectively. The difference between HCU and CR was statistically significant with respect to specificity but not sensitivity (P ¼ 0.008 and P ¼ 0.11, respectively). Conclusion: Due to its ease of use and its high diagnostic yield HCU systems of the latest generation constitute a helpful technique for the primary assessment of PE.

“…Four types of effusion fluid may be distinguished on US: (1) anechoic (similar to the contents of a simple cyst); (2) complex nonseptate (resembling that of a simple cyst with floating particles); (3) complex septate (similar to the contents of a complex cyst) (Fig. 4); (4) homogeneously hyperechogenic, which indicates a corpuscular effusion [3] ( Fig. 5).…”

“…Although computed tomography is still the imaging method of choice for the diagnosis of these conditions, thoracic US can be considered an important supplementary tool in this setting [3]. Today, thoracic US is mainly used to guide transthoracic biopsy of peripheral lung lesions and the drainage of pleural effusions [4].…”

Although numerous studies have been conducted on the use of ultrasonography (US) for the examination of thoracic structures, this procedure is not as widely accepted as abdominal US. The newer portable scanners can be used at the bedside to detect pleural malignancies and effusions, as well as peripheral lung nodules of the lung, even in seriously ill patients. Focal thickening of the pleura can be easily detected with US and further investigated with a US-guided biopsy. US guidance can also be used during percutaneous drainage of pleural effusion or transthoracic biopsy of peripheral lung lesions, thus reducing the incidence of procedure-related pneumothorax to almost zero. We review the current literature on thoracic US and present our clinical experience with the technique in large groups of patients with pleural and peripheral lung diseases.Sommario L'ecografia del torace non è ancora diffusa quanto quella addominale, nonostante una notevole quantità di studi ne attesti l'importanza. Le apparecchiature più recenti permettono di diagnosticare neoplasie, versamenti pleurici e noduli polmonari periferici al letto del paziente, anche nei casi più gravi. L'ispessimento pleurico focale è facilmente messo in luce dall'ecografia e può essere ulteriormente studiato tramite la biopsia ecoguidata. Questa può essere praticata anche su lesioni polmonari periferiche, riducendo quasi a zero il rischio di pneumotorace. In questo articolo esaminiamo la letteratura recente sull'ecografia del torace e presentiamo la nostra esperienza clinica su numerosi pazienti con patologia pleurica e della periferia polmonare. ª

“…transudates, simpie exudates, and complex exudates with malignant cells or infection [5]. In addition, subacute and chronic pleural hemomrhages, as well as chylous pleural effusions, can be recognized on the basis of MR signal intensity [4]. Lomigan and Libshitz [6] This signal intensity difference between malignant and benign pleural lesions on long-TA images was assessed by the observems as accurately visually as by ROI measurements.…”
