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.

A, B. T2WI and FLAIR image shows hyperintense lesions in the pons, and inferior cerebellar peduncles (red arrows), and in the callosomarginal interface in the deep white matter, which is characteristic of MS. C, D. Hyperintense lesions are also seen in the midbrain, and the superior cerebellar peduncle (red arrows). Figure 16.

Hamartomas can be seen as higher signals on T2, slightly higher signals on T1 without signs of compression. In about 43%-93% of patients with NF1 there are so called UBO (U. nidentified . B. right . O. bjects) lesions on MRI- hyperintensive signals on FLAIR and T2 weighted pictures, exclusively in the white matter without imbibition after contract.

[Mention the site of the lesion]. It showed low signal in T1WIs and high . signal in T2 and FLAIR WIs and exerts no mass effect on the adjacent . structures. NB. Old lacunar infarct will show low signal in T1 and FLAIR images with . high signal in T2WIs [CSF signal]. NB The same rule is applied for cases with multiple infarcts.

For both groups, the overall number of T2-bright lesions (defined as foci >3 mm2 of increased signal on the T2-FLAIR or T2-weighted spin-echo images), the number of well-defined ovoid and large (>1 cm) lesions, and the number of gadolinium-enhancing (Gd+) lesions were compared between the two age groups.

7.2 METHODS OF COLLECTION OF DATA (Including sampling procedures) In all patients detected to have intracranial lesions on MRI of the brain, at the Department of Radiodiagnosis basaveshwara hospital the DWI findings will be noted and correlated with ADC and T2 FLAIR images. Based on their signal intensity these lesions will be grouped into one ...

A, B and C: Brain MRI showed intense T2 Flair, T1 and DWI signal changes in the left basal ganglia (circle). D and E: Brain MRI showed intense T2 Flair signal changes in the left hippocampus and temporal lobe (asterisk), and right frontoparietal lobe (arrow), respectively. F: CUBE technique found no sign of meningitis.

3D T1-weighted, axial T2-weighted, axial fluid attenuated inversion recovery (FLAIR), and gradient echo sequences were acquired using an 8-channel phased array head coil. BOLD scanning was performed to assess CVR (see below) at 4mm isotropic resolution, with whole brain volume acquired every three seconds using the parameters published previously.1

Pathologic lesions can be separated into four major groups by their specific signal characteristics on the three basic images: T2-weighted, proton density-weighted (PD)/FLAIR, and T1-weighted. Since studies have shown that T2-weighted images are most sensitive for detecting brain pathology, patients with suspected intracranial disease should be ...

Symmetrical high signal intensity lesions are seen on the FLAIR and T2 images in the peri trigonal white matter (single arrows). Cribriform changes are present in the basal ganglion and thalamus. Red arrows represent white matter signal changes; blue arrows represent cystic or cribriform regions.

MRI: Pseudocystic multinodular, hypointense on T1, hyperintense on T2, no peritumoural oedema. May have mixed signal with bright rim on FLAIR. Pleomorphic xantoastrocytoma: WHO grade 2. Temporal lobe most common location. Usually benign, found almost exclusively in young adults, often long-standing temporal lobe epilepsy.

- strongly T2 weighted GRE sequence → combination of high signal levels and extremely high spatial resolution (excellent tissue/fluid contrast); flow-compensated, 2- or 3-dimensional gradient echo acquisition to obtain images with contrast that is proportional to the ratio of T2 relation time to T1 relaxation time → high signal-to-noise and ...
