Outcome: not reported Initial imaging: multiple T2 hyperintensities in brain and spine; two brain lesions with lamellar appearance and a ring of enhancement Initial imaging: no restricted diffusion Not performed Mowry EM et al. (2007)30 Presentation: 37-year-old woman who presented with acute left-sided weakness and numbness
What Does Hyperintensity Mean On An Mri Report? | HealthCentral
Magnetic resonance imaging is used to image and distinguish gray matter and white matter hyper intensities which appear as bright signals on the T2-weighted MRI images [2]. Using structural MRI, variations in water content in different parts of the brain provide contrast, which allows for the differentiation between the gray matter and the white matter [2].

DWI of brain MRI 2 months after onset demonstrated multiple small (< 2 cm in diameter) hyperintensities in the bilateral cerebral white matter (Figure 1).

On magnetic resonance imaging (MRI), an acute lacunar infarct is shown as hyperintense on diffusion-weighted imaging (DWI), hypointense on apparent diffusion coefficient map, hyperintense on T2-weighted and fluid-attenuated inversion recovery (FLAIR), hypointense on T1, and hypoattenuated on CT.

CK was slightly increased and CSF normal. TMS was normal and MRI of both the spinal cord and brain were normal (specifically, corticospinal tract (CST) hyperintensities on T2-weighted, proton density-weighted images were not found). Muscle biopsy has been performed with …

At the routine brain MRI, mild hyperintensities of the hippocampus and the anterior temporal lobe cortex were present bilaterally on FLAIR/T2-weighted images. CSF examination was normal.

It's possible that cerebrovascular-related brain lesions indicated by white matter hyperintensities on T2-weighted MRI could affect results. A histogram of total lesion volume (TLV) as measured . using the SPSS Lesion Segmentation Tool [44] revealed one outlier. This outlier was not exceptional in regard to other relevant variables.

Oct 31, 2014 · A, B) Images of 67 years old female having hypertension treatment. T2-weighted MRI (A) shows dot-like hyperintensities characteristic of PVS in the basal ganglia (BG: score 4). T2*-weighted MRI (B) shows rounded areas of signal loss characteristic of CMBs in BG and thalamus (arrows). C, D) Images of 63 years old female without hypertension.

WMH appearance on T1w MPRAGE and T2. MRI FLAIR (A) shows extensive confluent WMH. On MRI T1w MPRAGE, there is corresponding T1 hypointensity (arrow) in the regions affected by WMH, with T1 signal intensity greater than CSF and similar to that of normal-appearing gray matter.

Subsequently, all WM hyperintensities determined to be MS lesions were identified as well-defined focal areas of elevated MRI signal intensity in the FLAIR data, a T2-weighted MRI sequence with CSF water signal suppression. We applied a semi-automatic segmentation approach similar to the process used to derive demyelinated volume from MWF maps.
