Aim: To investigate the feasibility and prognostic value of biventricular strain analysis for patients with systemic lupus erythematosus (SLE) and relationship to left ventricular (LV) myocardial fibrosis, pulmonary hypertension (PAH), and right ventricular (RV) ejection fraction (RVEF).Materials and Methods: A total of 50 SLE patients (47 women; 34.4±12 years) and 15 controls (13 women; 32.9±8.6 years) were imaged via echocardiography and a 3 T magnetic resonance imaging (MRI). Pulmonary artery systolic pressure (sPAP) was assessed using echocardiography. Biventricular global circumferential strain (GCS), global longitudinal strain (GLS), global circumferential strain rate (GCSR), and global longitudinal strain rate (GLSR) as well as LV myocardial extracellular volume (ECV) were derived for each subject.Results: Elevated LV ECV was significantly associated with LV GCS (beta -0.428, p=0.000), GLS (beta 0.404, p=0.000), GCSR (beta -0.350, p=0.006), GLSR (beta -0.445, p=0.000) and RV GCS (beta -0.373, p=0.000), and the presence of reduced RVEF was significantly associated with LV GCS (beta -0.338, p=0.002), GLS (beta -0.465, p=0.000) and RV GCS (beta -0.465, p=0.000). Raised sPAP was significantly associated with RV GLS (beta 0.445, p=0.000) and GCSR (beta -0.387, p=0.001). Moreover, there were significantly correlations between LV and RV strain and strain rate.Conclusions: Biventricular strain analysis may be a better prognostic tool for patients with SLE as it allows greater comprehensive analysis and more definitive treatment planning compared to separate assessment of LV or RV contractility.

Aim: To investigate the usefulness of three-dimensional (3D) fast imaging employing steady state precession (FIESTA) magnetic resonance imaging (MRI) at 3 T in evaluating the intraparotid components of the facial nerve and parotid ducts, and to compare the MRI images with surgical findings., Materials and Methods: Thirty-one cases of benign parotid tumours were studied with conventional and 3D FIESTA MRI sequences at 3T using a head coil. The most clinically useful 3D FIESTA images were acquired at parameters of 4.9 ms repetition time (TR); 1.5 effective echo time (TEeff); a flip of 55°, a field of view of 18 to 20 cm, a matrix of 512 × 320, an axial plane, no gaps, and a section thickness of 1 mm. Post-processed multiplanar images were obtained with an Advantage Windows (AW sdc 4.3) workstation. Parotid ducts, facial nerves, and tumours were identified on these images. The relationship of the tumours to the facial nerves and parotid ducts was confirmed at surgery., Results: The facial nerves appeared as linear structures of low intensity. The main trunk of the facial nerve was identified bilaterally in 93.5% of the 3D-FIESTA sequence images. Parotid ducts appeared as structures of high intensity on multiplanar 3D-FIESTA images (100%). The relationships of the tumours with the cervicofacial and temporofacial divisions of the facial nerve were correctly diagnosed in 26 of 31 cases (83.9%) using 3D-FIESTA sequence images., Conclusion: 3D-FIESTA MRI at 3 T depicted the main trunk, cervicofacial and temporofacial divisions of the facial nerve, and the main parotid duct. It is useful for preoperative evaluation of parotid gland tumours., (Copyright © 2012 The Royal College of Radiologists. Published by Elsevier Ltd. All rights reserved.)
