Purpose.
Smooth muscle cells (SMCs) of cavernosum play an important role in erection.
It is of great significance to quantitatively analyze the level of SMCs in penis.
In this study, we investigated the feasibility of shear wave elastography (SWE) on evaluating the level of SMCs in penis quantitatively.
Materials and Methods.
Twenty healthy male rats were selected.
The SWE imaging of penis was carried out and then immunohistochemistry analysis of penis was performed to analyze the expression of alpha smooth muscle actin in penis.
The measurement index of SWE examination was tissue stiffness (TS).
The measurement index of immunohistochemistry analysis was positive area percentage of alpha smooth muscle actin (AP).
Results.
Sixty sets of data of TS and AP were obtained.
The results showed that TS was significantly correlated with AP and the correlation coefficient was −0.618 ( p < 0.001 ).
The result of TS had been plotted against the AP measurements.
The relation between the two results has been fitted with quadric curve; the goodness-of-fit index was 0.364 ( p < 0.001 ).
Conclusions.
The level of SMCs in penis was successfully quantified in vivo with SWE.
SWE can be used clinically for evaluating the level of SMCs in penis quantitatively.
