摘要: Gastric schwannomas (GSs) and gastrointestinal stromal tumors (GSTs) are grossly similar submucosal neoplasms with different prognoses. We explored the value of spectral computed tomography (CT) to distinguish between them. METHODS Patients diagnosed GS or GST at Lanzhou University Second Hospital, China, May 2013 June 2015 were included retrospectively. The subjects underwent CT examination before surgery had histologically confirmed diagnosis GST. RESULTS Twelve patients (3 men; 9 women; mean [SD] age, 47.0 [11.5] years) 20 (7 13 54.7 [9.9]) showed significant differences in terms arterial phase (AP) 70 keV (P < 0.001), portal (PP) = 0.002), AP iodine concentration, PP water slope curve, curve (all P 0.001). CONCLUSIONS Spectral may be useful for noninvasive tumors.
