Venetian Blind Artifact

Venetian blind artifact 3d mra only this is a specific artifact seen only with the motsa multiple overlapping thin slab acquisition technique.

Venetian blind artifact.

Any tissue particularly dense and hard tissues and tissue with various densities including bone uterus and brain. 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. 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. It has been attributed to either hardening of the tissue in the paraffin block or defective assembly of the microtome knife.

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. The motsa technique is described in more detail in another q a. Parallel undulations shown in the lower image of varied thickness. 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.

Thick thin areas venetian blinds washboarding undulations and skipping. 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. Venetian blind shadowing is a type of posterior acoustic artifact described as bands of linear shadows along lines of sight often diverging on a convex probe 1. Description quick overview with artifact information reason and help for the mri artifact.

Smaller 3d volume or scans with e g. The latter may be seen with either adenomyosis or uterine fibroids. It represents overlap between adjacent slabs that are acquired as separate acquisitions and then fused together. 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.

It has been attributed to either hardening of the tissue in the paraffin block or defective assembly of the microtome knife. Rain shower 2 appearance is a sonographic finding that is typically associated with adenomyosis but can also occur in uterine fibroids. 3 article feature images from this case.
