Abstract
Different type of fibroid shows different response to MR guided HIFU, which is believed to reflect different blood suplly. ADC value derived from low b multiple b value DWI may reflect perfusion information. Our study is to assess the relationship of AUC (area under curve) calculated from the temperature curve during sonication in MR guided HIFU therapy for fibroid and the diffusion coefficient derived from multiple b-values DW-MRI in patient screening.
Highlights
Background/introduction Different type of fibroid shows different response to MR guided HIFU, which is believed to reflect different blood suplly
IVIM MR images were acquired on the axial plan across the uterus
Freehand ROIs circumscribing the fibroids were drawn and data was analyzed by using DWI post- processing software performed in a proprietary programming environment (PRIDE; Philips Medical Systems)
Summary
Background/introduction Different type of fibroid shows different response to MR guided HIFU, which is believed to reflect different blood suplly. Methods A total of 50 uterine fibroids (diameter: mean, 5.6 cm; range, 3.5–8 cm) in 45 female patients (mean age, 44.8 years) who were given written informed consent underwent MRI screening.
