Characterization of breast lesions using diffusion kurtosis model-based imaging: An initial experience.

Objective: To investigate the characterization of breast lesions using diffusion kurtosis model-based imaging.

Methods: This prospective study included 120 consecutive patients underwent preoperative DCE-MRI examinations and multi-b-value diffusion-weighted imaging (DWI). Among them, 88 malignant lesions and 44 benign lesions were detected, 56 normal fibroglandular breast tissue were selected as normal control.

Preliminary clinical application of integrated 125I seeds stents in the therapy of malignant lower biliary tract obstruction.

Purpose: To evaluate the clinical efficacy of percutaneous trans-hepatic integrated 125I seed stents implantation for malignant lower biliary tract obstruction.

Methods: Thirty-two patients with malignant lower biliary obstruction were randomly divided into two groups. One group underwent the therapy with integrated 125I seed stents (Test group, n = 13), and another group received conventional metal stents implantation for treatment (Control group, n = 19).
