Magnetic resonance images resembling jugular venous thrombosis

Juglar venous blood flow resembled venous thrombosis on magnetic resonance images (MRI) in three cases. We present these cases together with MRI of juglar venous thrombosis and also discuss on flow signals and thrombus through the clinical cases and the experimental study. Left jugular angiography showed hemostasis in two of three cases and normal venous flow in one. In clinical cases and experimental study the blood clot appeared high intense on spin echo image (SE) and inversion recovery image (IR). Water flow appeared high intense at a certain range of velocity on SE and IR. Consequently the normal venous flow as well as hemostasis can look like thrombus on MRI. (author)
