BACKGROUND: The liver and spleen have a similar amount of blood perfusion, and the spleen is waterier than the liver. The spleen tissue has a higher contrast-enhanced computed tomography (CT) extracellular volume fraction than the liver. The spleen has been reported to have a much lower apparent diffusion coefficient (ADC), intravoxel incoherent motion (IVIM)-perfusion fraction (PF), and IVIM-D METHODS: This study utilized a random selection of authors' historical liver IVIM magnetic resonance imaging (MRI) data. For 1.5T data, SDC was calculated with RESULTS: The median ratio of SDC CONCLUSIONS: The spleen has a faster diffusion than the liver, HCCs have a faster diffusion than the adjacent liver parenchyma, and hemangiomas have a faster diffusion than simple cysts. Although it is known that cysts have a substantially longer T2 than hemangiomas, SDC of hemangioma was higher than that of cysts, suggesting 'T2 effect' is minimized for SDC.
