Abstract：Objective To evaluate the effectiveness of multi-slice spiral computerized tomography angiograph ( MDCTA ) in determining vascular invasion in patients with musculoskeletal tumors, and to compare the results with the surgical ifndings.Methods From January 2008 to June 2014, 21 patients diagnosed musculoskeletal tumors with vascular invasion based on magnetic resonance imaging ( MRI ) underwent MDCTA examination before surgical treatment. Their clinical data were retrospecitvely analyzed, including 11 cases of limb bone tumors and 10 cases of limb soft tissue tumors. There were 12 males and 9 females, whose mean age was 33 years old. The double-blind method was used to determine the presence of vascular invasion based on MDCTA examination results. The statistical analysis was carried out by using surgical ifndings as the gold standard.Results Twelve patients without vascular invasion according to the MDCTA examination were also surgically negative ( true negative ). Among the 9 patients with vascular invasion shown by the MDCTA examination, only 3 patients had adhesions and were considered surgically negative ( false positive ). The other 6 patients had vascular invasion proven by surgery and were considered surgically positive ( true positive ). Based on the surgical ifndings, the sensitivity of MDCTA was 100%, speciifcity 80%, positive predictive value 66.7%, negative predictive value 100%, and accuracy 85.7%.Conclusions MDCTA is an accurate imaging technique in evaluating vascular invasion of musculoskeletal tumors, which can provide valuable and authentic imaging information.
