Long-term outcomes of vertebroplasty for osteoporotic compression fractures.
This study aimed to determine outcomes of percutaneous vertebroplasty for osteoporotic vertebral compression fractures (VCFs). ⋯ Vertebroplasty provides significant and clinically meaningful reductions in pain, analgesic use, and disability in the short, medium and long term. Compared with conservative therapy, vertebroplasty provides significantly greater functional improvement and reduction in analgesic use. The procedure is relatively safe with no clearly increased risk of new vertebral fractures.

Fusion of high b-value diffusion-weighted and T2-weighted MR images improves identification of lymph nodes in the pelvis.
Accurate identification of lymph nodes facilitates nodal assessment by size, morphological or MR lymphographic criteria. We compared the MR detection of lymph nodes in patients with pelvic cancers using T2-weighted imaging, and fusion of diffusion-weighted imaging (DWI) and T2-weighted imaging. Twenty patients with pelvic tumours underwent 5-mm axial T2-weighted and DWI (b-values 0-750 s/mm(2)) on a 1.5T system. ⋯ Nodal visualisation was better using fusion images compared with T2-weighted images (mean RIDIT score 0.689 vs 0.302). Fusion of diffusion-weighted MR with T2-weighted images improves identification of pelvic lymph nodes compared with T2-weighted images alone. The improved nodal identification may aid treatment planning and further nodal characterisation.
