Abstract:
Gastrointestinal stromal tumors (GISTs) are common mesenchymal neoplasms in the gastrointestinal tract.The results of computed tomography play important roles in the diagnosis,treatment planning and follow up of GISTs. From August 2007 to January 2012,28 patients with GISTs were admitted to the Henan Provincial People's Hospital. Sixteen tumors showed extra-luminal growth,4 showed intra-luminal growth,7 involved both intra- and extra-luminal growth,and 1 showed extra-gastrointestinal growth.After administration of contrast media,9 tumors demonstrated homogeneous enhancement,18 showed heterogeneous enhancement and 1 showed non-obvious enhancement.The enhancement of tumors in arterial and venous phase was 20 Hu higher than that in plain scan.Angiogenesis was displayed in 6 tumors,and feeding arteries were observed in 3 tumors.
