Common and Uncommon Artifacts in T1 FLAIR SAG Sequences …
Weba report, CSF flow-related artefact in the basal cisterns occurs in about 40–80% of fast FLAIR images [2]. This artefact is uncommon over the convexities of the brain in which CSF motion is diminished. CSF flow-related artefact can be diminished by modifying the sequence using a non-slice-selective inversion pulse with a KRISP WebDOI: 10.1016/0899-7071(94)00085-9. Abstract.

WebThe purpose of this article is to review the normal appearance of CSF, flow physics in relation to CSF flow dynamics, and commonly encountered appearances and artifacts of CSF due to superimposed flow effects. CONCLUSION. WebWe have noted that fast-spin-echo T2-weighted images of the cervical and thoracic regions of the spine can produce low-signal artifacts in the spinal subarachnoid space which might be misinterpreted as tumor or abnormal vascular flow voids. These are possibly related to complex cerebrospinal fluid p … WebBackground and purpose: Our purpose was to test a new variant of the fluid-attenuated inversion-recovery (FLAIR) sequence that was designed to reduce CSF and blood flow artifacts by use of a non-slice-selective inversion pulse and k-space reordered by inversion time at each slice position (KRISP). Methods: With the KRISP FLAIR sequence, the slice … citizens bank waterford mi
