Circulating tumor cells (CTCs) are tumor cells that originate from primary cancer tissues, enter the bloodstream in the body, and metastasize to the other organs. Simple and convenient methods for their detection, capture, and recovery from the blood of cancer patients would be highly desirable. We report here on a simple and convenient methodology to trap, culture, and re-collect cancer cells, the sizes of which are greater than those of normal hematologic cells, by the use of glass-bead filters (GBFs).

Detection of anomalous cells such as cancer cells from normal blood cells has the potential to contribute greatly to cancer diagnosis and therapy. Conventional methods for the detection of cancer cells are usually tedious and cumbersome. Herein, we report on the use of a particle size analyzer for the convenient size-based differentiation of cancer cells from normal cells.

Objective: The aim of this study was to evaluate the usefulness of reconstructed computed tomography (CT) images using OsiriX software in detecting wooden and bamboo foreign bodies.

Methods: Four sizes of wet and dry wooden and bamboo foreign bodies were selected to be analyzed. Those in the air and in the head of edible swine were scanned with a multidetector row CT scanner.

Purpose: We investigated whether images of stationary objects obtained by segmental acquisition with positron emission tomography using 2-deoxy-2-[(18)F]-fluoro-D: -glucose (FDG-PET) are of a quality equivalent to those obtained by conventional continuous acquisition.

Materials And Methods: Phantoms filled with FDG and mid-abdominal regions of 18 patients who underwent FDG-PET tests were imaged by both continuous and segmental acquisition methods. The total acquisition time was set to 3 min; in the segmental acquisition mode, imaging for 15 s was repeated 12 times.
