Malignant Pleural Disease: Diagnosis by Using Diffusion-weighted and Dynamic Contrast-enhanced MR Imaging—Initial Experience

Abstract

DW imaging is a promising tool for differentiating MPD from benign lesions, with high accuracy, and supplementation with DCE MR imaging seems to further improve sensitivity.

2015 ESC Guidelines for the diagnosis and management of pericardial diseases

“…Ponadto wprowadzenie nowych technik, w tym obrazu zależnego od dyfuzji i dynamicznego wzmocnienia po kontraście, otwiera drogę do jeszcze dokładniejszej oceny budowy struktur antomicznych w przypadku obecności guzów w rzucie osierdzia [122].…”

Can diffusion weighted MRI differentiate between inflammatory-infectious and malignant pleural effusions?

“…They concluded that DWI can differentiate malignant pleural diseases from benign lesions with high accuracy especially with the combination of DCE-MRI. They also concluded that by using a purely ADC-based diagnosis, false-negative diagnoses may occur mostly due to necrotic and inflammatory area within the tumor (12).…”

Usefulness of Diffusion-weighted Magnetic Resonance Imaging-guided Biopsy: Pyothorax-associated Lymphoma

“…It is beginning to be used for the staging and response assessment of lymphomas (7)(8)(9)(10). Because DW-MRI of extracranial lesions has only just begun, there are only a few reports about its usefulness for evaluating pleural disease (11,12) and identifying appropriate areas for biopsies of intrathoracic lesions (13,14). There are no reports about its usefulness for determining optimum biopsy sites of pleural disease.…”
