Neuroimaging, An Issue of Neurologic Clinics

The latest book, Neuroimaging, An Issue of Neurologic Clinics, by Laszlo Mechtler contains the most up to date information regarding Neurologic Clinics, and the use of transcranial Doppler (TCD).

“Since the introduction of TCD by Rune Aaslid in 1982, the most important technical advancement has been the addition of power motion-mode Doppler (PMD) to the single-channel TCD screen. Before PMD, TCD provided only spectral waveforms that were not obvious to clinicians because they had no imaging or depth-perception information attached to them, and multiple waveforms from different depths had to be put together to identify vessels and pathologic changes. PMD detects not only the presence of flow but also its depth, direction, and resistance to memorize these parameters.”
