Venetian Blind Artifact Radiology

It has classically been described in uterine adenomyosis 2 3 as.

Venetian blind artifact radiology.

Ironic to its name it resembles vertical blinds rather than the classic horizontal appearance of venetian window blinds figs. Venetian blind artifact 3d mra only this is a specific artifact seen only with the motsa multiple overlapping thin slab acquisition technique. High resolution imaging of the carotid arteries is possible when image quality is of greater concern than acquisition time. The slabs typically overlap 25 40 to minimize the venetian blind artifact venetian blind artifact due to minimal saturation effects.

This gives rise to the so called venetian blind artifacts shown in the image left. It represents overlap between adjacent slabs that are acquired as separate acquisitions and then fused together. Images with 1 mm or less spatial resolution in all three planes are required. 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.

Rain shower 2 appearance is a sonographic finding that is typically associated with adenomyosis but can also occur in uterine fibroids 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. 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. The venetian blind a k a.

Ironic to its name it resembles vertical blinds rather than the classic horizontal appearance of venetian window blinds figs. 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. 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.
