[Weighted-averaging multi-planar reconstruction method for multi-detector row computed tomography].

Development of multi-detector row computed tomography (MDCT) has enabled three-dimensions (3D) scanning with minute voxels. Minute voxels improve spatial resolution of CT images. At the same time, however, they increase image noise.

[Perioperative complications of patients with cementless femoral head replacement].

Background: Studies have shown that use of cement is a risk factor for fat embolism in elderly patients with femoral neck fracture. We investigated the usefulness of the cementless femoral head replacement technique.

Methods: A retrospective study of 58 patients who had undergone this technique between January 1995 and May 2001 was conducted.
