Abstract Objective To explore the diagnostic value of high-field 1.5T MRI in closed splenic trauma. Methods The 1.5T magnetic resonance image information about 54 patients with closed splenic trauma confirmed by pathology or follow-up was retrospectively analyzed and compared with the CT image during the first visit. Intrasplenic hematoma and splenic capsule hematoma were chosen as direct diagnostic signs while uneven density or signals, an increase in volume, rough edges and hemoperitoneum were regarded as indirect diagnostic signs. The difference in the number of direct and indirect signs detected by MRI and by CT imaging was studied. Results Among the 54 cases of splenic trauma, 46 were diagnosed by CT during the first visit, 5 were suspected, and 3 cases were missed, compared with 51 and 3 diagnosed by MR that had no missed cases. MRI detected not only more intrasplenic hematomas than CT, but fewer splenic capsule hematomas and indirect signs. The difference between the two groups was statistically significant(P＜0.05). Conclusions There is something unique about MRI imaging of splenic of trauma, which can complement CT examination in some occult cases, and is of more referential value for the diagnosis and treatment of splenic trauma.
