New permanent magnet designs have recently enabled portable devices to perform relaxometry studies in compact and inexpensive low-field systems. For these sensors, protocols for fast acquisitions of T1-T2 correlations maps are widely desired due to their potential application in process and quality control in industries. Fast pulse sequences based on Continuous Wave Free Precession (CWFP) [1] and Driven Equilibrium (DE) [2] regime are potential candidates for these fast protocols. Recently, it has been demonstrated that CWFP, using low flip angle (CWFP-T1), can be combined with CPMG (Carr-Purcell Meiboom-Gill) and PGSE (Pulse Gradient Spin Echo) to obtain T1–T2 [3] and diffusion-T1 [4] correlation maps, respectively. Furthermore, a pseudo-bi-dimensional (2D) DECPMG has shown to be a fast alternative method to 2D ones to obtain T1-T2 correlation maps [2]. 2D-CWFP sequences were compared to conventional methods to determine fat/oil content and water compartmentalization in general food samples [3,4], while the DECPMG experiment was employed as a potential method for identifying oil and water in rocks [2]. In this work, we evaluate and compare the T1-T2 conventional method (IR-CPMG: Inversion Recovery-CPMG) with the fast methods 2D CPMG-CWFP-T1 and the pseudo-2D DECPMG for phantom and castor-bean oil samples. The results demonstrated that the 2D CPMG-CWFP-T1 has a shorter experimental time and yield higher resolution 2D maps than IR-CPMG. The pseudo-2D DECPMG method has the shortest experimental time among the three methods, however, with much lower resolution 2D correlation maps.
