| Research Abstract |
Near infra-red spectroscopy is presently applied to detect cerebral blood flow changes of the capillary network. We have found that this method is applicable to detect larger blood flow changes at the extremities or the trunk in a human body. In this study, we measured portal vein blood flow change safely and continuously.
We were able to detect portal vein blood flow changes qualitatively but not quantitatively. Even with this limitation, it is expected that blood flow change reflects digestive function of the intestines and may help examine the general condition of a subject and provide the impetus for an early checkup. The equipment with this device used in our study is inexpensive, therefore, it may be suitable for home-use.
