Abstract：Objective: To explore the application value of the technique of SENSE MRV in lower limb veins. Methods: Without SENSE technique and with SENSE technique were performed in 34 patients suspected with venous diseases of the lower limb. Contrast enhancement were not used in all examinations. Results: All cases acquired excellent image and anatomic changes in the lower limb veins. The scan time with SENSE technique of reduction factor 2.0 in lower limb veins imaging decreased about 50% of the counterparts without SENSE technique and the contrast resolution on SENSE imaging almost kept the same as that on conventional sequence. Changing the parameters which enhance resolution as the same as scanning scope and time may obviously improve the picture quality. Conclusion: It offers a new approach to reduce the scan time at preserved spectral resolution, SENSE technique shows a widen promising in fast MRI and clinical application.
