Characterization of ultrasound propagation through ex-vivo human temporal bone.

Adjuvant therapies that lower the thrombolytic dose or increase its efficacy would represent a significant breakthrough in the treatment of patients with ischemic stroke. The objective of this study was to perform intracranial measurements of the acoustic pressure field generated by 0.12, 1.

Fast-recovery fast spin-echo T2-weighted MR imaging: a free-breathing alternative to fast spin-echo in the pediatric abdomen.

In the mid 1990s, the fast spin-echo (FSE) and turbo spin-echo (TSE) T2-weighted (T2-W) sequences became available and are now widely accepted alternatives to conventional spin-echo sequences since they result in reduced acquisition times while maintaining tissue contrast. Since that time, there has been continued development of new sequences to further decrease acquisition times, minimize artifacts, and preserve lesion detection. The purpose of this pictorial essay is to qualitatively illustrate the newly available fast recovery (FR) FSE T2-W MR images of the abdomen compared with the images acquired using the routine FSE T2-W sequence in non-breath-hold studies in children.

Occlusion of a giant splenic artery pseudoaneurysm with percutaneous thrombin-collagen injection.

Splenic artery pseudoaneurysms have been conventionally treated with surgical or endovascular techniques, including transcatheter embolization. This case report describes the use of procoagulant components thrombin and collagen in large volume to percutaneously embolize a giant splenic artery pseudoaneurysm.
