Comparative StudyA phantom study comparing ultrasound-guided liver tumor puncture using new real-time 3D ultrasound and conventional 2D ultrasound.
The purpose of this study is to compare the accuracy of ultrasound-guided puncture using new real-time 3D (4D) ultrasound and conventional 2D ultrasound for focal hepatic masses using a liver phantom. ⋯ Four-dimensional ultrasound-guided puncture for liver tumors can markedly improve puncture accuracy for both experienced and inexperienced physicians compared with conventional 2D ultrasound guidance.

Whole-body diffusion-weighted MRI with apparent diffusion coefficient mapping for early response monitoring in multiple myeloma: preliminary results.
The purpose of our study was to prospectively assess the feasibility of whole-body diffusion-weighted imaging (DWI) for short-term evaluation of response to treatment in multiple myeloma patients using a single-shot echo-planar imaging DWI sequence with a Stejskal-Tanner diffusion encoding scheme and spectral fat suppression. ⋯ Whole-body DWI with ADC analysis represents a feasible diagnostic tool for assessment of short-term treatment response in myeloma patients.
