Previous work by our group has detailed a high level of repeatability using the phantom, showing consistent PET and MR perfusion calculations with a manually set perfusion rate [23].
For non-binding conditions, trends of the height equivalent to a theoretical plate (HETP) as a function of reduced velocity are consistent with perfusion.
For non-binding conditions, the trends in height equivalent to a theoretical plate (HETP) as a function of mobile phase velocity and molecular size are consistent with perfusion suggesting that a fraction of the mobile phase between 0.0005 and 0.0008 flows through the particles.
Again, these findings are consistent with perfusion changes seen by micro-ultrasound following treatment of these tumors with aflibercept (Fig. 3e, f).
ASL has been adopted for migraine aura and hypoperfusion was detected, consistent with former perfusion studies [14, 15].
The FCR (d) of tracer from normoxic hearts was consistent throughout the perfusion protocol and was unaffected by either GSH augmentation or depletion.
Subsequent scans, however, showed this focus to be enlarging with increased perfusion, consistent with a recurrent and progressive tumor.
Histological examination of the sections showed that AS7 and AS12 tumours exhibited a high degree of tissue heterogeneity, central necrosis and reduction of viable tissue, consistent with insufficient perfusion, compared with the more homogeneous and viable parental C6 gliomas.
As expected, enzyme release was higher in the group of patients with impaired EF consistent with impaired tissue perfusion.
Therefore, it is important to control the physiologic factors that can affect blood flow such as blood pressure, pulse rate, and body temperature for consistent measurement of tissue perfusion.
These results are consistent with previous CT and MRI perfusion studies between HCC and colorectal liver metastasis.
