characterization of soft tissue tumors by diffusion-weighted imaging
conclusion our preliminary results have shown that although there is some overlap between benign and malignant tumors, adding dwi, mr imaging to routine soft tissue tumor protocols may improve diagnostic accuracy. results there was only one patient with a malignant cystic tumor and was not included in the statistical analysis. the median adc values of benign and malignant tumors were 2.31 ± 1.2...
متن کاملCharacterization of Soft Tissue Tumors by Diffusion-Weighted Imaging
BACKGROUND Diffusion-weighted imaging (DWI) is a noninvasive method for investigation of tumor histological content. It has been applied for some musculoskeletal tumors and reported to be useful. OBJECTIVES The aim of the present study was to prospectively evaluate the apparent diffusion coefficient (ADC) values of benign and malignant soft tissue tumors and to determine if ADC can help diffe...
متن کاملCharacterization of Bone and Soft Tissue Tumors at MRI
MRI protocol Optimal characterization of musculoskeletal tumors at MRI involves certain basic requirements. High-resolution, small-field-of-view axial T1-weighted spin-echo and fatsuppressed T2-weighted fast (turbo) spin-echo images should be obtained through the entire tumor. T1-weighted images are critical in showing the presence of fat or hemorrhage within a mass; distinguishing normal marro...
متن کاملTumor spatial heterogeneity in myxoid-containing soft tissue using texture analysis of diffusion-weighted MRI
The objective of this study was to examine the tumor spatial heterogeneity in myxoid-containing soft-tissue tumors (STTs) using texture analysis of diffusion-weighted imaging (DWI). A total of 40 patients with myxoid-containing STTs (23 benign and 17 malignant) were included in this study. The region of interest (ROI) was manually drawn on the apparent diffusion coefficient (ADC) map. For textu...
