Application of Laser Doppler Flowmetry in Neurosurgery

Neurosurgery Clinics of North America, 1996
Experience with LDF has indicated that intraoperative estimation of cerebral blood flow can be very useful and that long-term recordings of cortical perfusion pressure are possible. The disadvantage of LDF is that measurements are extremely local and that the units of measurements are arbitrary.

Laser Doppler Flowmetry in Asymmetric Glaucoma

Current Eye Research, 2005
To evaluate the relationship between extent of glaucoma damage and optic nerve blood flow, we investigated optic nerve head bloodflow in patients with asymmetric glaucoma damage between their two eyes and also in glaucomatous eyes with asymmetric damage inferiorly versus superiorly.From our institutional practice, 16 subjects with asymmetric glaucoma ...

[Laser-Doppler flowmetry].

Nihon rinsho. Japanese journal of clinical medicine, 1992
Laser-Doppler flowmetry (LDF) is a non-invasive technique for measuring the tissue blood flow. It has been shown in the skin that LDF discloses blood flow fluctuations due to vasomotor nerve activity. LDF can give measurements of blood flow at various sites of different tissue.

Laser Doppler Flowmetry for monitoring traumatized teeth

Dental Traumatology, 2001
Abstract – Laser Doppler Flowmetry (LDF) has been shown to be valuable in monitoring revascularization of immature incisors following severe dental trauma. Several investigators have demonstrated the ability of LDF to record blood flow signals from vital tooth pulps.

Waveform analysis applied to laser doppler flowmetry

Microsurgery, 1986
AbstractLaser Doppler flowmetry (LDF) has been found useful in monitoring free flaps. In the present study, waveform analysis has been applied to the LDF waveform. Waveform changes were investigated in the microcirculation during varying degrees of arterial or venous occlusion in the saphenous island and flap of the dog and the human digit.

Vaginal Laser Doppler Flowmetry Pre- and Posthysterectomy

Journal of Sex & Marital Therapy, 2004
The objective of this study was to demonstrate the applicability of laser doppler flowmetry to pre- and posthysterectomy vaginal blood flow assessment. We used laser Doppler flowmetry to measure pre-and postoperational vaginal blood flow in 8 premenopausal women undergoing benign hysterectomies; we also measured serum E2, FSH, FT and administered a ...

The lamp effect of laser Doppler flowmetry on teeth

Journal of Oral Rehabilitation, 2005
summary  The aim of this study is to analyse the intra and extracoronal scattering of laser light. Twelve vital teeth from 12 volunteer individuals (aged 22–29 years) were used. The camera removing the charge coupled device's infrared cut filter was used for imaging the laser Doppler flowmetry light during pulpal blood flow measurement.

The anatomy of the human promontory for laser Doppler flowmetry

European Archives of Oto-Rhino-Laryngology, 1997
Studies of the dynamic characteristics of cochlear blood flow (CBF) utilizing laser Doppler flowmetry (LDF) in laboratory animals have provided a new approach to the understanding of control mechanisms of CBF and the role of the CBF in cochlear disorders. However, few studies exist indicating that LDF of human CBF may be possible. Since bone thickness,

Laser Doppler Flowmetry in Animals

2012
This chapter will describe the technique known as laser Doppler fl owmetry and its use in animals. Because the technique is based on light, it permits noninvasive measurements of perfusion in a tissue that can be illuminated, but perhaps its greatest strength is that it provides a continuous measurement.

Evaluation of Laser Doppler Flowmetry in Renal Transplantation

Journal of Clinical Laser Medicine & Surgery, 1994
Renal grafts are presently evaluated based on the surgeon's observation of the organ microcirculation. Effectiveness of organ microcirculation has traditionally been accomplished through evaluation of the appearance of the graft. Laser doppler flowmetry (LDF) has been suggested as a possible means to determine graft effectiveness.
