A wide variety of cystic lesions may be encountered in the soft tissues and bones during routine MR imaging of the knee. These lesions represent encapsulated fluid collections and exhibit low signal intensity on T1-weighted images and high signal intensity on T2-weighted images because of their high content of free water. Many lesions produce clinical(More)
PURPOSE To show the effectiveness of positioning the arm in abduction and external rotation (ABER) during magnetic resonance (MR) arthrography for depiction of tears of the rotator cuff. MATERIALS AND METHODS Five throwing athletes with shoulder pain were prospectively imaged with standard MR imaging, MR arthrography, and ABER MR arthrography. The status(More)
We have made year-long observations of sinking particle #uxes with sequential sediment traps moored at a depth of 200 m at three sites proceeding o!shore from Vancouver Island, Canada in water depths of 500}2500 m. Total particle #ux and biogenic silica decreased o!shore as expected in an eastern boundary current regime. No obvious gradient was observed in(More)
The following three cases are reported since they provide an opportunity for further defining the condition that has been termed primary pulmonary arteriosclerosis. It may be difficult to distinguish clinically from cardiac disease secondary to long-standing pulmonary disease. Brenner (1935) states that: " before the diagnosis of primary pulmonary(More)
1066-033X/14©2014ieee c ontrol textbooks sometimes give the impression that amplification and phase shift are properties confined to asymptotically stable systems. For example, [1, p. 400] states that “Any system with a pole in the RHP is unstable; hence it would be impossible to determine its frequency response experimentally because the system would never(More)
