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.
Venetian blind artifact mri.
Venetian blind artifact 3d mra only this is a specific artifact seen only with the motsa multiple overlapping thin slab acquisition technique.
This gives rise to the so called venetian blind artifacts shown in the image left.
The venetian blind a k a.
Adenomyosis is a common benign uterine condition and a frequent cause of pelvic pain in premenopausal women.
Description quick overview with artifact information reason and help for the mri artifact.
Reformatting artifacts improper mip and reformations may give the false appearance of vessel occlusion or stenosis when it is only partially included in the mip volume.
It has been attributed to either hardening of the tissue in the paraffin block or defective assembly of the microtome knife.
It represents overlap between adjacent slabs that are acquired as separate acquisitions and then fused together.
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.
Smaller 3d volume or scans with e g.
Magnetic resonance angiography mra is a group of techniques based on magnetic resonance imaging mri to image blood vessels.
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.
The saturation effect of inflowing blood in 3d inflow mra.
Magnetic resonance angiography is used to generate images of arteries and less commonly veins in order to evaluate them for stenosis abnormal narrowing occlusions aneurysms vessel wall dilatations at risk of rupture or other abnormalities.
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.
