Abstract
Clinical imaging equipment technological advancements offer insight into the evolution
of mathematical techniques used to estimate parameters necessary to characterize the microvasculature
and, thus, differentiate normal tissues from abnormal ones. These parameters are blood flow
(F), capillary endothelial permeability surface area product (PS), vascular fraction (vp), and extravascular
extracellular space size (EES,ve). There are a number of well-established approaches that
exist in the literature; however, their analysis is restricted by complexity and is heavily influenced
by noise. On the other hand, these characteristics can also be calculated using simpler and straightforward
approaches such as Up-Slope Method (USM) and Graphical Analysis (GA). The review
looks into the theoretical background and clinical uses of these methodologies, as well as the applicability
of these techniques in various sections of the human body.
Keywords:
Angiogenesis, microvasculature, Up-Slope model, graphical analysis, unidirectional model, bidirectional model.
