Role of diffusion-weighted imaging in the differential diagnosis of benign and malignant lesions of the chest-mediastinum

Abstract

Short-tau inversion-recovery echo-planar imaging (STIR-EPI) sequences applied to the chest-mediastinum provided potentially useful images for the differential diagnosis of benign and malignant lesions.

Diagnostic Performance of Diffusion Weighted Imaging of Malignant and Benign Pulmonary Nodules and Masses: Comparison with Positron Emission Tomography

“…DWI can be used to distinguish benign from malignant lesions in the lung Ohba et al, 2009;, in the thorax (Tondo et al, 2011), in the prostate (Yamamura et al, 2011), in the breast (Fornasa et al, 2011), and in the liver (Koike et al, 2009;. DWI was reported to be superior to FDG-PET in the detection of primary lesions and the nodal assessment of non-small cell lung cancers (Usuda et al, 2011;Wu et al, 2012).…”

Recurrence and Metastasis of Lung Cancer Demonstrate Decreased Diffusion on Diffusion-Weighted Magnetic Resonance Imaging

“…The diagnostic efficacy of DWI is superior to that of PET-CT, and DWI can be used in assessment of malignancy in pulmonary nodules and mass lesions instead of PET-CT. Similarly, DWI can be used to distinguish benign from malignant lesions in the lung (Mori et al, 2008;Ohba et al, 2009), in the thorax (Tondo et al, 2011), in the prostate (Yamamura et al, 2011), in the breast (Fornasa et al, 2011) and in the liver (Koike et al, 2009). DWI was reported to be an effective alternative in future diagnosis and follow-up of bladder tumors because of its higher sensitivity, specificity and accuracy (Ceylan K et al, 2010).…”

Contribution of MRI in lung cancer staging

“…In the latter situation the DWI is more accurate than other sequences including T2-weighted normal (35). MRI always keeps a place in the characterization of silicotic nodules of patients exposed to silica with no signal on T2-masses (26)(27)(28)(29)(30)(31)(32)(33) (Table I). MR is as accurate as 18 F-FDG PET/CT for nodule or masses characterization (Fig.…”
