zero.1-T human fat/water separation by SIDAC

High-resolution human fat/water separated images were obtained in 17 min at a static magnetic field strength as low as 0.1 T. The sequence used was based on SIDAC (spectroscopic imaging by dephasing amplitude changing), which employs a stepwise changing dephase gradient for the separation of spectral and spatial information of magnetic spins.

[A new technique for intramuscular injections (author's transl)]

Among the methods for intramuscular injection, Hochstetters technique into the gluteus medius muscle is anatomically sound, but there are a few practical defects which make it difficult to perform. The method we describe has been tested and is simpler. Anatomical orientation is easier, vessels and nerves are not endangered, asepsis is better guaranteed, and the injection can be given with the patient in any position, even lying down. Instead of Hochstetters method of injecting into the vastus lateralis muscle, in which three connecting lines must be drawn mentally, we use our simple method: the injection is given in the middle third of the thigh, dorsal to a line joining the anterior superior iliac spine and the lateral border of the patella.
