Cerebral microhemorrhages is a smaller form of hemorrhagic parenchymal contusion and are typically found in white matter. Such microhemorrhages are difficult to be detected on CT scan, but easily detected on gradient echo and susceptibility weighted imaging on MRI scan as hypointense susceptibility blooming.
Images of CAA collected at 1.5 T. Left, conventional T2* (TE=20 ms), center, SWI processed magnitude image (TE=40 ms) and right, SWI phase image (TE=40 ms) Gradient recalled echo (GRE) imaging is the conventional way to detect hemorrhage in CAA , however SWI is a much more sensitive technique that can reveal many micro-hemorrhages that are ...
CAA is associated with brain hemorrhages, particularly microhemorrhages.The accumulation of amyloid beta peptide deposits in the blood vessel walls results in damage of the blood vessels and hindrance of normal blood flow, making blood vessels more prone to bleeding [10] Since CAA can be caused by the same amyloid protein that is associated with Alzheimer's dementia, brain bleeds [11] are more ...
Intracerebral hemorrhage (ICH), also known as hemorrhagic stroke, is a sudden bleeding into the tissues of the brain (i.e. the parenchyma), into its ventricles, or into both.
However, this proves to be very susceptible to measurement noise, so increasingly complex measures were developed to capture the measure while minimizing the noise. An important element of these calculations is the sum of squares of the diffusivity differences = (λ 1 − λ 2) 2 + (λ 1 − λ 3) 2 + (λ 2 − λ 3) 2. We use the square root ...
Cerebral infarction, also known as an ischemic stroke, is the pathologic process that results in an area of necrotic tissue in the brain (cerebral infarct). [1] In mid to high income countries, a stroke is the main reason for disability among people and the 2nd cause of death. [2]
Indian 2 grossed ₹ 50 crore (US$5.8 million) on its opening day, which was the highest first day gross for a Tamil film in 2024, with over ₹ 25 crore (US$2.9 million) from India. [58] The film became the second highest opening day gross for both Haasan and Shankar, behind Vikram (2022) and 2.0 (2018). [59]
Methagu 2 was released on 19 August 2022 on the OTT platform tamilsott.com. [4] [5] Kalki of Tamil Guardian noted "despite its flaws, Methagu 2 is an important film in archiving the history of man who grew to be the leader of both the Tamil Tigers and of a movement that continues to have significant impact on the Tamil homeland and around the world".
