Abstract：The spleen is the most vulnerable abdominal parenchymal organ. Accurate detection, diagnosis and evaluation of the severity of splenic parenchyma and vascular injury by radiologists is crucial for selection of clinical treatment strategies. Multidetector computed tomography (MDCT) is the first choice for hemodynamically stable patients. The American Association for Surgery of Trauma Organ Injury Scale (AAST-OIS) scale is the most widely used tool to guide clinical treatment based on spleen parenchymalinjury. The authors conduct a review from aspects of MDCT diagnosis, AAST-OIS classification and treatment, prognosis evaluation and imaging follow-up of patients with blunt splenic injury, in order to provide more help for radiologists and trauma surgeons.
