Results

 

Our research contained 54 patients treated in the Dmitry Rogachev National Research Center of Pediatric Hematology, Oncology and Immunology (Tbl.1). On CT images we evaluated characteristics of the x-ray density of a tumor on different phases of contrast enhancement: native – 34 ± 8 HU, 1CE - 49 ± 15 HU, 2CE – 60± 22 HU. Also, the involvement of near bone structures made up 70% and presence of calcinates was in 40% of cases. (Fig. 2) On MRI 83% of tumors were isointensive on T1 WI, 92% of cases was hyperintensive on T2 WI, ACD – 1505х10-6 ± 488х10-6 mm2/s and 79% of tumors actively accumulated contrast agent. (Fig. 3) All patients were separate on two groups of histology: embryonal and alveolar RMS. The analysis of ADC did not identify any statistically significant (Student's t-test, Mann-Whitney test) differences between these groups (p<0,05)
