PURPOSE To evaluate white matter disorders with magnetization transfer (MT) techniques. MATERIALS AND METHODS In 46 healthy volunteers and 46 clinical patients, MT Z spectra were obtained with various continuous-wave-equivalent MT powers (B1CW) and frequency offsets. RESULTS With B1CW of 270 Hz and 4,000-Hz frequency offset, the MT ratio of normal(More)
BACKGROUND A bioelectronic middle ear microphone (BMEM) has been developed in a laboratory bench model and successfully tested in fresh human temporal bones. A transducer actually has been bench-tested in our laboratory; it was implanted in chronic animal experiments (cats) as well as in humans for a period of 1 year as a driver of a semi-implantable(More)
