What is the meaning of stromal echogenicity?
Although the stromal echogenicity appears subjectively brighter, this is primarily a reflection of the difference between the echogenicity of the stroma compared with that of the entire ovary. There was an increased stromal index as well as an increased stromal volume in women with polycystic ovaries.
What is stromal content?
Stromal cells, or mesenchymal stromal cells, are differentiating cells found in abundance within bone marrow but can also be seen all around the body. They are cells that support the function of the parenchymal cells of that organ. The most common stromal cells include fibroblasts and pericytes.
What is the meaning of ovarian stroma?
The ovarian stroma is the substance of the ovary—a connective tissue that binds structures together and is enriched with blood vessels, cells, and several hundred thousand follicles.
What is echogenicity in ovary?
Conclusions: Small echogenic foci in the ovaries are most frequently due to hemosiderin or calcification. A few small echogenic foci in the ovaries are associated with benign histologic changes and do not appear to be reliable indicators of endosalpingiosis or endometriosis.
What does stromal cells mean?
Listen to pronunciation. (STROH-mul sel) A type of cell that makes up certain types of connective tissue (supporting tissue that surrounds other tissues and organs).
Where do stromal cells come from?
Mesenchymal stromal cells (MSCs) are the spindle shaped plastic-adherent cells isolated from bone marrow, adipose, and other tissue sources, with multipotent differentiation capacity in vitro.
What are stromal cells?
What is ovarian stroma Class 12?
– The ovaries are surrounded by a capsule-like structure having an outer cortex and an inner medulla. – The entire ovarian stroma is highly vascular. The stroma of the ovary contains the interstitial cells that resemble the interstitial cells of the testis.
What is the size of ovaries with PCOS?
These criteria are based on a review of the literature comparing women with PCOS with healthy control subjects. According to the consensus definition, polycystic ovaries are present when (a) one or both ovaries demonstrate 12 or more follicles measuring 2–9 mm in diameter, or (b) the ovarian volume exceeds 10 cm3.
How do you calculate total stromal echogenicity?
The total stromal echogenicity was calculated as the product of the mean stromal intensity and the total number of pixels measured in the same two-dimensional ultrasound image of the stroma.
Is there a difference in stromal echogenicity between women with polycystic ovaries?
There was no difference in the mean stromal echogenicity, although the stromal index was significantly greater in women with polycystic ovaries.
What is echogenicity and why is it important?
In other words, echogenicity is higher when the surface bouncing the sound echo reflects increased sound waves. Tissues that have higher echogenicity are called “hyperechogenic” and are usually represented with lighter colors on images in medical ultrasonography. In contrast, tissues with lower echogenicity are called “hypoechogenic”…
What causes echogenicity to be high on ultrasound?
Reasons for higher echogenicity. During ultrasound examinations, sometimes echogenicity is higher in certain parts of body. Fatty liver could cause increased echogenicity in the liver, especially if the liver transaminases are elevated. Women with polycystic ovary syndrome may also show an increase in stromal echogenicity.
