Summary:Objective To explore the features of various mediastinal lymphadenopathies using computed tomographyperfusion （CTP）.Methods CTP parameters （CTPs） of the selected mediastinal nodes from 59 patients withpathology-proven malignant lymph nodes and of those from 29 patients with clinically diagnosed orpathology-proven inflammatory lymphadenopathies were collected. Patients were divided into subgroups byetiology and phase of primary disease, including different pathological malignant nodes and diverseinflammatory nodes. CTPs were defined as blood flow （BF）, blood volume （BV）, mean transit time （MTT）,permeability （PMB）, and time to peak （TTP）. Differences of CTPs were compared between malignant andbenign nodes, and among subgroups, respectively.
