Material decomposition images of the water-calcium base pair were generated and assessed in conjunction with the monochromatic images to permit correlation of marrow signal changes with any cortical disruption for fracture confirmation. The assessment was performed by two musculoskeletal radiologists blinded from MRI results. The statistical difference of MRI and reviewers\u2019 detection of acute bone oedema (1 = present, 0 = absent) was performed using the Friedman test (SPSS v.16).<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>MRI showed acute scaphoid fracture and\/or bone marrow oedema in 14\/20 patients of which 6 also had cortical disruption. On DECT, reviewer A identified oedema in 13 and cortical disruption in 10 patients while reviewer B identified oedema in 10 and cortical disruption in seven of the 14 MRI positive patients. No statistically significant difference in oedema detection on MRI and reviewers of DECT (<jats:italic>p<\/jats:italic> value 0.61) but DECT was more sensitive at detecting cortical disruption.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusion<\/jats:title>\n                <jats:p>DECT has the capability to detect acute scaphoid oedema in addition to cortical fractures.
