Taken together, our findings suggest that midline shift is an independent predictor of clinical outcomes after acute stroke, irrespective of reperfusion and/or thrombectomy therapy. Midline shift greater than 3mm was identified as a critical threshold with clinical relevance.

Jul 4, 2024 · Midline shift is one of the most important indicators of increased intracranial pressure due to mass effect. Any intra-axial or extra-axial lesion (tumor, hemorrhage, abscess, etc.) has the potential to exert mass effect on the brain parenchyma and cause lateral shift of …

Noncontrast CT scan is the preferred initial imaging study for stroke patients because it can identify hyperdense hemorrhage and differentiate it from cerebral infarction, guiding immediate intervention along with NIHSS score.

Midline shift (arrow) is present in this brain after a stroke (infarct depicted in shaded area). Midline shift is a shift of the brain past its center line. [1] The sign may be evident on neuroimaging such as CT scanning. [1]

Midline shift determined on MRI or CT images is a well-validated marker of mass effect after large hemispheric infarction and associated with mortality. In this study, we targeted a population with moderately sized strokes.

Nov 20, 2018 · Midline shift is a finding described on transverse (axial) slices from CT and MRI studies. It describes the situation where the midline of the intracranial anatomy is no longer in the midline and is the result of pushing or pulling forces within either side …

Mar 12, 2022 · Midline shift was measured on follow-up imaging between days 0 and 6 after stroke. We evaluated Pearson’s correlation between the KM index and the amount of midline shift. The mean KM index of all patients was 1.01 ± 0.09 (decompressive hemicraniectomy subgroup 1.13 ± 0.13; midline shift subgroup 1.18 ± 0.13).

Sep 29, 2023 · The presence of a significant MLS was defined by a deviation of the septum pellucidum from the midline on follow-up CT scans of at least 3 mm or greater due to the mass effect of ischemic edema.

Midline Shift and Herniation: Axial CT scan of the brain at the level of the basal ganglia. Note the large infarction in the distribution of the left middle cerebral and posterior cerebral arteries.

Sep 24, 2009 · MR diffusion-weighted imaging (DWI) is the most sensitive and specific technique available for demonstrating acute infarction within minutes after its occurrence, 14 and this can be combined with MR perfusion (MRP) to differentiate viable from probably nonviable hypoperfused tissue. 15–17 In the same examination, MR angiography (MRA) can demonst...
