Patient histories that include wrist pain can be pivotal in the distinction between intersection syndrome (IS) and the more common de Quervain's tenosynovitis (DQT). Presented here is a 26-year-old pregnant woman with a history of rowing who developed left radial/dorsal wrist pain and a rubbing/squeaking sensation. Nine months of conservative DQT therapy and a landmark-guided corticosteroid injection failed to relieve her symptoms. An in-clinic ultrasound showed tenosynovitis at the intersection of the first and second compartments, confirming a diagnosis of IS...

Identification of vascular structures from medical images is integral to many clinical procedures. Most vessel segmentation techniques ignore the characteristic pulsatile motion of vessels in their formulation. In a recent effort to automatically segment vessels that are hidden under fat, we motivated the use of the magnitude of local pulsatile motion extracted from surgical endoscopic video. In this article we propose a new approach that leverages the local orientation, in addition to magnitude of motion, and demonstrate that the extended computation and utilization of motion vectors can improve the segmentation of vascular structures...

yclodialysis is the result of the separation of the longitudinal fibres of the ciliary muscle from their scleral insertion, creating states of ocular hypotony. It is mainly caused by traumatisms. Gonioscopy has traditionally been the diagnostic test for this entity, however, at present it is being replaced by other techniques, such as ultrasound biomicroscopy (UBM). We present the case of a 57-year-old male who, following a traumatism in the left eye caused by the disc of a radial saw, presented corneal perforation and vitreous haemorrhage with pan-retinal edema...

Peripheral intravenous and intra-arterial catheters often block with movement of the limb in which they are inserted. Although the cause of this blockage is commonly attributed to a valve or other structure within the vein, evidence for this is lacking. We used ultrasound to assess the cause of blockage on movement, and degree of tip movement, of 62 venous and 21 radial arterial catheters. In both venous and arterial catheters, blockage was predominantly caused by impingement of the catheter on the vessel wall, with catheter kinking and spasm of the vessel also seen...

PURPOSE: Arrhythmias can be treated by ablating the heart tissue in the regions of abnormal contraction. The current clinical standard provides electroanatomic 3- D maps to visualize the elec-trical activation and locate the arrhythmogenic sources. However, the procedure is time-consuming and invasive. Electromechanical Wave Imaging is an ultrasound- based non-invasive technique that can provide 2-D maps of the electromechanical activation of the heart. In order to fully visualize the complex 3-D pattern of activation, several 2-D views are acquired and processed separately They are then manually registered with a 3-D rendering software to generate a pseudo-3-D map However, this last step is operator-dependent and time-consuming...
