The CT scanners revealed that "Acupuncture points have a higher density of micro-vessels and contain a large amount of involuted microvascular structures. The non-acupuncture points did not exhibit these properties."
Another study saw researchers use an amperometric oxygen microsensor to detect partial oxygen pressure variations at different locations on the anterior aspect of the wrist. It showed a direct correlation of increased oxygen pressure with known and commonly used acupuncture points.
This is only confirming what acupuncturists have known for centuries but it is one step further to proving that the concept of qi or energy flowing through the body is not hocum. Acupuncturists have always thought that acupuncture points are simply areas where the qi pools and at this point an acupuncturist would use the conductive nature of the needles to manipulate that persons qi. This research shows this to be correct and is a huge finding for researchers and the acupuncture community.
