To study the application of magnetic resonance elastography (MRE) in the human brain. ⋯ MRE could be an imaging technique for assessing the elasticity of brain tissue.
-
To evaluate the antitumoral effects of an intra-arterial injection of 3-bromopyruvate (3-BrPA) on liver VX2 tumor in rabbits. ⋯ A single session of intra-arterial injection of 3-BrPA showed no better results in terms of tumor necrosis than that of saline injection in a rabbit VX2 tumor model.
-
To examine the value of cutting-balloon percutaneous transluminal angioplasty (PTA) for hemodialysis access with residual stenosis after conventional balloon PTA. ⋯ Additional cutting-balloon PTA was found useful for reducing residual stenosis.

Comparative Study
Pulmonary perfusion in acute pulmonary embolism: agreement of MRI and SPECT for lobar, segmental and subsegmental perfusion defects.
To assess prospectively the agreement of magnetic resonance (MR) pulmonary perfusion with single-photon emission computed tomography (SPECT) perfusion for perfusion defects down to the subsegmental level in patients with suspected pulmonary embolism (PE). ⋯ The very high agreement of MR perfusion with SPECT perfusion enables the detection of subtle findings in suspected PE.

Comparative Study
Quantitative assessment of regional emphysema distribution in patients with chronic obstructive pulmonary disease (COPD).
To compare objective and subjective assessment of the distribution of emphysema in unselected patients with chronic obstructive pulmonary disease (COPD). ⋯ We found significant discrepancies between the objective and subjective distributions of emphysema in various morphological patterns, which may be of clinical importance in, for instance, lung-volume-reduction surgery.
