“…Thanks to the ongoing improvement of ultrasound technology, sonographic images can now be automatically optimized with elimination of artifacts like the second harmonic and the digital compound. This trend could further modify normal visualization of anatomic tissues, eliminating the interference and misleading effects of the numerous artifacts that are normally present in the thoracic cavity [22]. Artifacts are "imaging errors" caused by physical processes that affect the ultrasound beam and in some way alter the basic assumptions the operator makes about the beam [23].…”

KEYWORDSTransthoracic; Normal pleuropulmonary; Pneumonectomy space; Ultrasound artifacts.Abstract Interest has been increasing in the use of transthoracic ultrasound for the study of the pleuropulmonary disease. US imaging depends mainly on the physical interactions between ultrasound waves and the tissues being examined. In the thoracic region, the prescence of the chest wall and the air-containing pulmonary tissues cause various artifacts that strongly influence the resulting images. At the interface between tissues and air, the ultrasound beam is totally reflected and produces simple reverberation, comet-tail artifacts, and ring-down artifacts. We report the findings of transthoracic ultrasound in normal healthy subjects and in those who had undergone pneumonectomy.This experience shows that, in terms of the ultrasound artifacts mentioned above, the postpneumonectomy cavity is not significantly different from the healthy lung.Sommario SommarioL'interesse nell'utilità dell'ecografia del torace si è di recente accresciuto specialmente nello studio delle malattie pleuro-polmonari. L'immagine ecografica dipende prevalentemente dalle interazioni fisiche tra gli ultrasuoni e i tessuti esaminati; pertanto nello studio del torace la presenza della gabbia toracica e del tessuto polmonare contenente aria influenza fortemente le immagini generando molteplici artefatti. Il fascio ultrasonoro passando attraverso l'interfaccia tessuti/aria è quasi totalmente riflesso, producendo semplici riverberazioni (artefatti orizzontali), "comet-tail" e "ring-down" (artefatti verticali). Riportiamo gli effetti fisici implicati nella formazione di artefatti durante l'ecografia del torace in soggetti normali confrontati con lo spazio residuo post-pneumonectomia. In tutti i soggetti sani esaminati così come nella cavità residua dopo pneumonectomia abbiamo rilevato tutti gli artefatti descritti in accordo con i principi fisici degli ultrasuoni. ª

“…Previous studies have demonstrated that LUS may identify ILD in patients with SSc by assessing the number of B-lines 20–23. In a previous study on 33 patients with SSc who independently underwent LUS and chest HRCT within 1 week, a LUS score was obtained by totalling the number of B-lines on the anterior and posterior chest and then compared with ILD quantified by HRCT with the previously described 30-point Warrick score 22.…”

“…B-lines are the sonographic sign of pulmonary interstitial involvement,17 including increased thickness of the pulmonary septa. Traditionally, B-lines have been employed in patients with heart failure to detect the location and quantification of extravascular lung water,15–19 but many data suggest their use also in evaluating ILD 17 20–23. Assessment of B-lines by LUS would represent an attractive biomarker for the frequent evaluation of pulmonary involvement in patients with SSc since it is non-ionising, inexpensive and easy to perform and interpret.…”

“…Lung ultrasound shows some promise as a radiation-free method of screening for the development of supervening ILD in CTD based on the identification of ‘B-lines', vertical artefacts arising from the pleural space representing the sonographic sign of interstitial lung involvement [29,30]. Lung ultrasound is inexpensive, widely available, reproducible and easily performed at the bedside, in combination with echocardiography [31,32].…”

The monitoring of lung involvement in patients with connective tissue diseases is central to optimal long-term management and is directed towards: (a) the detection of supervening lung involvement not present at presentation and (b) the identification of disease progression in established lung disease. For both goals, accurate surveillance requires multi-disciplinary evaluation with the integration of symptomatic change, serial pulmonary function trends and imaging data. Evaluated in isolation, each of these monitoring domains has significant limitations. Symptomatic change may be confounded by a wide variety of systemic factors. Pulmonary function tests provide the most reliable data, but are limited by measurement variability, the heterogeneity of functional patterns and the confounding effects of non-pulmonary factors. Chest radiography is insensitive to change but may provide rapid confirmation of major disease progression or alert the clinician to respiratory co-morbidities. Although high-resolution computed tomography has a central role in assessing disease severity, it should be used very selectively as a monitoring tool due to the associated radiation burden. Ancillary tests include echocardiography and exercise testing to proactively identify cases of pulmonary hypertension and worsening of oxygenation. In summary, a multi-disciplinary approach is essential for the identification of disease progression and prompt treatment of comorbidities that severely impact on the morbidity and mortality of disease.
