Underwater gliders are robust ocean sensor platforms characterized by high reliability and endurance. Due to their relatively low speed, the motion of underwater gliders is strongly affected by ocean currents, which provides data to estimate the depth averaged flow velocity. The glider computerized tomography (Glider CT) algorithm reconstructs a depth-averaged flow field from the navigation err...

Results For the global EF, Bland-Altman analysis showed significantly higher agreement between CT and MRI (p 0.005, 95% confidence interval: 14.2%) than for CVG ( 20.2%) and 3D Echo ( 21.2%). Only CVG (59.5 13.9%, p 0.03) significantly overestimated EF in comparison with MRI (55.6 16.0%). CT showed significantly better agreement for stroke volume than 2D Echo, 3D Echo, and CVG. In comparison wi...

PURPOSE To evaluate the influence of different reconstruction intervals of retrospectively electrocardiographically (ECG)-gated multi-detector row computed tomographic (CT) angiography on image quality of different segments of various types of coronary artery bypass grafts. MATERIALS AND METHODS Twenty consecutive patients with 62 grafts underwent retrospectively ECG-gated four-channel multi-...

OBJECTIVE To investigate the clinical value of renal perfusion imaging in patients with aortic dissection (AD) using 320-row computed tomography (CT), and to determine the relationship between renal CT perfusion imaging and various factors of aortic dissection. METHODS Forty-three patients with AD who underwent 320-row CT renal perfusion before operation were prospectively enrolled in this st...

Fig. 1 shows the images of a 44-year-old woman, who was diagnosed of an alveolar rhabdomyosarcoma of the right heel (dotted arrow in B), during her second trimester of her pregnancy. After diagnosis, she underwent delivery by elective cesarean. In the initial staging of the disease, she had an extensive lymph node involvement of inguinal, iliac and retroperitoneal territories detected by contra...
