Case Report: Infection After Cholecystectomy.

Background: is a non-tuberculous mycobacterium and is found everywhere in the environment. However, infection in human is extremely rare, especially in immunocompetent individuals. It is difficult to detect infection because its symptoms are non-specific, and routine diagnostic tests are less sensitive.

[Three-dimensional mini-type permanent magnetic resonance imaging device and medical imaging of mice].

We developed a three-dimensional mini-type permanent magnetic resonance imaging (MRI) device in our lab. The purposes of this study were (1) for further development of MRI technologies, (2) for support of broadening practices of animal test modeling in medical research, and (3) for training more specialists from colleges or universities in the field of MRI. This paper describes the research and development at our lab(s), especially stressing on the design of the main magnet, the gradient coil and the radio frequency coil.
