The venetian blinds artifact is an uncommon tissue cutting artifact that leads to the formation of parallel series of strips of tissue separated from one another by narrow clear spaces.
Description quick overview with artifact information reason and help for the mri artifact.
Thick thin areas venetian blinds washboarding undulations and skipping.
Closing the venetian blinds.
The venetian blind appearance associated with adenomyosis is typically thin whereas when associated with uterine fibroids there are also edge shadows or dense posterior shadowing from calcification 1.
The summary below examines the most common microtomy artifacts that can be seen under the microscope when viewing stained tissue sections.
Ultimately since both leiomyomas and adenomyosis are common they can coexist.
Description quick overview with artifact information reason and help for the mri artifact.
It has been attributed to either hardening of the tissue in the paraffin block or defective assembly of the microtome knife.
In some cases adenomyosis can be overlooked in the presence of large leiomyomas.
Venetian blind artifact from motsa because each motsa slab is acquired at separate times exact registration of position and signal intensity of adjacent slabs may not be possible.
Ultrasound features of adenomyosis including asymmetrical uterine wall thickening anteriorly with focal heterogeneity and associated increased blood flow as well as the venetian blind pattern of acoustic shadowing the latter may be seen with either adenomyosis or uterine fibroids.
This gives rise to the so called venetian blind artifacts shown in the image left.
Venetian blind artifact 3d mra only this is a specific artifact seen only with the motsa multiple overlapping thin slab acquisition technique.
Some types of tissue are more prone to certain kinds of artifacts.
It represents overlap between adjacent slabs that are acquired as separate acquisitions and then fused together.
Rain shower 2 appearance is a sonographic finding that is typically associated with adenomyosis but can also occur in uterine fibroids.
While both leiomyomas and adenomyosis can have venetian blind shadows leiomyomas are more likely to have edge shadows or if densely calcified to have impenetrably dense shadows.
