However, teeth that have temporarily or permanently lost sensory function due to trauma may not respond to sensibility testing despite the presence of an intact vasculature.4 Direct measurement of pulpal blood flow (PBF) provides the most accurate and reliable assessment of pulp status.5 Laser Doppler flowmetry
(LDF) is a well-documented, non-invasive technique that provides direct, objective measurements of blood circulation.
Moreover, mean arterial pressure measured during microvascular flowmetry
(MAP-F) was higher in hypertensive patients than in normotensive controls, both before and after sildenafil administration.
The study outlined key steps in their processing methods - including image filtering, motion detection, and masking - that brought photoacoustic flowmetry
an important step closer to clinical applicability, according to the journal editor, Andreas Mandelis.
Laser Doppler flowmetry
monitoring of the local cerebral blood flow demonstrated that inducing ischemia diminished the blood flow to less than 20% of the baseline throughout the 45 minutes' MCAO in all the groups, whereas the blood flow did not change in the sham-operated group (figure 1).
Then, laser speckle flowmetry
was used to determine the blood flow of the lower extremities of the rats in each group.
Skin scores and recently more sensitive tools including laser Doppler flowmetry
, Doppler US, and MRI have been used for evaluation and monitoring of the lesions .

While SD-OCT is typically slower than SS-OCT, it offers superior phase stability and axial resolution, which is beneficial in Doppler flowmetry
or capillary imaging that require high phase stability and fine axial resolution.

Furthermore, preoperative imaging reports, intraoperative flowmetry
, and postoperative histopathological examinations were screened to assess splenomegaly, portal hypertension, and cirrhosis, respectively.
Cerebral blood flow was monitored by Laser-Doppler flowmetry
, and only those mice with 90% of blood flow blockade during MCAO and 85-95% recovery of blood flow during reperfusion were used for further experiments.
