Multiple MRI techniques exist that assess the health of the knee cartilage. Assessment of T2 relaxation time is useful in such situations. In the assessment of knee cartilage abnormalities, 2D-FSE imaging is most often used in clinical practice, providing excellent SNR between tissues; qDESS imaging is useful in assessing morphological changes; and CubeQuant is a highly SNR efficient 3D T2 quantification method. The purpose of our study was to evaluate whether the T2 measurements as acquired through qDESS and CubeQuant techniques have similar relaxation times in healthy participants compared to T2 measurements acquired through the 2D-FSE technique.
