“…Eur Respir J 1998;11: 1392-1404 and the spatial resolution is approximately 1-2 mm. In diseases of the pleura and the chest wall or pulmonary processes near or in contact with the pleura, surface coils may be used with reduction of the FOV down to 8 cm, allowing for an excellent spatial resolution of 0.3 mm [11]. This may be followed by a fast non-gated T2-weighted sequence in one plane corresponding to the T1-weighted images, for up to 26 images within 4-6 min [11,41].…”

“…In diseases of the pleura and the chest wall or pulmonary processes near or in contact with the pleura, surface coils may be used with reduction of the FOV down to 8 cm, allowing for an excellent spatial resolution of 0.3 mm [11]. This may be followed by a fast non-gated T2-weighted sequence in one plane corresponding to the T1-weighted images, for up to 26 images within 4-6 min [11,41]. The T2-weighted images display suspected increased SI and are helpful in showing fluid collection, distinguishing tumour from fibrosis, or chest wall musculature, and identifying flow phenomena, but the anatomical resolution is poor.…”

“…Contrast-enhanced MR may be useful in pulmonary and mediastinal masses to detect necrosis or fibrosis [3-5, 7-13, 19, 20, 23, 28], and differential diagnosis may be improved [9][10][11][12][13]. Especially in pleural diseases, in pulmonary processes adjacent to the pleura, and in chest wall changes, contrast-enhanced T1-weighted MR has been found to be advantageous because of its improved ability to delineate lesions from normal structures [8][9][10][11]. For imaging vascular structures and diagnosing cardiac and vascular abnormalities, fast or dynamic imaging techniques are most valuable.…”

“…In peripheral carcinomas, contact with the pleura may suggest malignant involvement of the pleura, or of the adjacent chest wall. A thin layer of extrapleural fat separating the tumour mass from the chest wall can almost always be seen on high quality or high-resolution MR images [8,9,11,31]. In such cases contrast enhanced T1-weighted MR is superior to CT in the demonstration of malignant involvement.…”

“…Although some correlations have been found both in vitro and in vivo between MR SI and pleural fluid composition, MR cannot differentiate between various aetiologies of pleural effusions, but can distinguish free and loculated effusions, as well as identify coexistent underlying lung disease [9,11,31]. An accurate demonstration of pleural fluid composition is difficult with MR, but blood in the pleural space is distinguishable from other fluids, except for acute bleeding [41].…”

To date, magnetic resonance (MR) is established as an imaging modality in the diagnosis of chest diseases. Because of its excellent distinction of vessels and soft tissue, MR can be performed as the primary imaging procedure before computed tomography in patients with suspected vascular lesions, mediastinal masses, hilar lesions, and pathological changes of the pleura and the chest wall. In these cases, MR is able to provide all the necessary diagnostic information. In other patients, a limited number of MR images may be helpful in cases of equivocal or confusing CT or clinical findings. More detailed information can be obtained, using surface coils or special imaging sequences, i.e. high resolution MR images of the pleura or angiographic images of mediastinal and pulmonary vasculature. From a clinical viewpoint, the most important task for thoracic magnetic resonance nowadays is the pretherapeutic evaluation of intrathoracic masses, the differential diagnosis of benign versus malignant lesions, and the accurate documentation of tumour extent in malignancies including three-dimensional-display to improve surgical or radiation planning. Future directions in thoracic magnetic resonance will be predominantly influenced by postprocessing approaches, specialized imaging techniques, and magnetic resonance-guided interventional applications.

Introduction: To describe the value of contrast-enhanced ultrasound (CEUS) for the differentiation of malignant from benign parietal pleural lesions (PPLs).Materials and Methods: From November 2005 to June 2019, 63 patients with histologically/cytologically confirmed PPLs were investigated by CEUS. On CEUS, the extent of enhancement (EE; marked or reduced/absent) and the homogeneity of enhancement (HE; homogeneous or inhomogeneous) were analyzed retrospectively.Results: In total, 24/63 lesions were benign, and 39/63 lesions were malignant. On CEUS, 11/24 benign and 36/39 malignant lesions showed a marked enhancement.A marked enhancement was significantly more frequently associated with malignancy compared with benign lesions (p < 0.001). In five cases, due to the absence of enhancement, it was not possible to determine the HE. In the remaining cases, 9/20 benign and 19/38 malignant lesions showed an inhomogeneous enhancement (p = 0.79). Conclusion:On CEUS, marked enhancement was significantly more frequently associated with malignant compared with benign lesions. However, some benign lesions, such as chronic inflammatory processes, may also show a marked enhancement.Therefore, the interpretation of perfusion patterns in these lesions must always take into account the clinical background of the patient.
