Methods and materials
45 patients with biopsy-proven DT were diagnosed in a tertiary-level healthcare hospital (Vall d'Hebron,
Spain) from 2002 to 2017.
After excluding 3 patients with intraabdominal DT,
42 patients with extraabdominal and abdominal wall DT were included in our descriptive review.
MR was performed at diagnosis and during follow-up.
10 MR performed at diagnosis (23.8%) included functional sequences,
so semiquantitative analysis of tumour perfusion with SI/T curves (signal intensity/time) could be performed.
Patient age and sex,
treatment and outcome were recorded.
shape and margins along with T1,
T2 and STIR signal intensities and heterogeneity were assessed on MR at diagnosis.
Statistical evaluation was performed using the Kruskal-Wallis test or Fisher's exact test for continuous quantitative and qualitative variables.
Multiple linear regression analysis was calculated to identify factors that were independently predictive of aggressiveness of DT.
SPSS software version 21 (SPSS,
A two-tailed p-value <0.05 was considered statistically significant.
