conclusion high-resolution mr images of the wrist using 3d t2space, pd blade and t2 blade were superior to those using conventional sequences quantitatively. high-snr and cnr mr imaging with space and blade would be a promising method to diagnose wrist lesions. results snr of the cartilage, tfcc on 3d t2space and t1 fse was better than other sequences (p < 0.001). snr of the bone on pd blade wa...

As previously discussed, because of differences in anatomy, there are differences in techniques for intubating the trachea of infants and children compared with adults.[1–4,17–19,99,114,115] Because of the smaller dimensions of the pediatric airway there is increased risk of obstruction with trauma to the airway structures. A technique to be avoided is that in which the blade is advanced into t...

OBJECTIVES To prospectively compare the diagnostic performance of a non-Cartesian k-space sampling T2-weighted TSE BLADE sequence with a conventional T2-weighted TSE sequence in female pelvic organs. METHODS Forty-seven patients with sonographically indeterminate adnexal masses or uterine lesions underwent sagittal BLADE and conventional TSE at 1.5 T after glucagon administration. Two radiolo...

We created a model physical system to investigate the role of blade rigidity in setting forces and rates of mass exchange for a blade exposed to unsteady flow in a vortex street. Using a combination of experimental and theoretical investigations, we find that, broadly, both the forces and the mass exchange are higher for more flexible blades. Below a critical value of the dimensionless blade ri...

~The design of axial-flo~ turbines has been hampered in the past by a lack of comprehensive data regarding pressure losses and gas deflections through rows of turbine blades. In the present report much of the available information relating to this subject is studied and analysed to determine magnitudes of gas pressure losses and deflections in a wide variety of blade rows and also to determine ...

The Drosophila wing imaginal disc gives rise to three body parts along the proximo-distal (P-D) axis: the wing blade, the wing hinge and the mesonotum. Development of the wing blade initiates along part of the dorsal/ventral (D/V) compartment boundary and requires input from both the Notch and wingless (wg) signal transduction pathways. In the wing blade, wg activates the gene vestigial (vg), w...
