Magnetic Resonance Direct Thrombus Imaging (MRDTI) uses a 3D highly T1-weighted fat-suppressed acquisition to visualise methaemoglobinrich thrombi whilst suppressing surrounding sources of high signal. We applied the same core MRDTI approach to the female pelvis to locate blood products within endometriotic lesions. Application of the MRDTI sequence increased detection of small endometriotic foci. Superimposition onto T2WI improved anatomical localization and differentiation of endometriotic foci from other cystic lesions in the pelvis. This technique may provide a reliable and non-invasive means of diagnosing, quantitating and following up endometriosis.
