   Jun 24, 2020 · Citation, DOI, disclosures and article data. T2 blackout effect is a diffusion-weighted imaging phenomenon, representing the reverse of T2 shine through. The 'true' diffusion signal (as determined by ADC values) is reduced on DWI images (e.g. b=1000) by the presence of very low T2 signal (on b=0 images).

   A blackout, or transient loss of consciousness (T-LOC) occurs because there is: a disorder of the circulation—syncope; a disorder of the brain—epilepsy (or other rare neurological condition); a disorder of the psyche—psychogenic seizures. It is clear from referral patterns and current care pathways that many doctors assume that T-LOC is usually caused by epilepsy, but in fact syncope is ...

   In T2-blackout, lesions with very short T2 (or T2*) values reduce signal intensity in the DW image, potentially masking or destroying its diffusion sensitivity. In extreme cases even the ADC map calculation will be affected and unreliable. An example of T2-blackout is shown below for a subacute hematoma. The T2*-weighted b0 image has extremely ...

   Why does one blackout happen?

   • THUMP: Why exactly does one blackout? Dr. Mader: The affect of alcohol on the brain is sedative, because it’s poisonous to our cells. When you drink in excess, brain cells stop communicating as fast and precisely with one another. That means less information can be transmitted, which is what causes the blackout.

   Does alcohol cause a blackout?

   • Dr. Mader: The affect of alcohol on the brain is sedative, because it’s poisonous to our cells. When you drink in excess, brain cells stop communicating as fast and precisely with one another. That means less information can be transmitted, which is what causes the blackout. Are there certain types of alcohol that facilitate having blackouts?

   Why do T2 shine-through and T2 blackout occur?

   • The reason both T2-shine-through and T2-blackout occur relate to the nature of the DW (trace) image. By definition the DW image is diffusion - weighted, not a map of diffusion. The DW image is strongly dependent on diffusion, but also reflects underlying T2, spin-density, and T1 effects.

   Is a blackout a partial or complete blackout?

   • Depending on how much those receptors are disrupted, a blackout can be either partial or complete. Partial blackouts are scientifically known as “fragmentary” and commonly known as “brown-outs”. Complete blackouts are scientifically called “en bloc” and sometimes referred to as “that never happened”.

   Jul 18, 2024 · The Biology of a Blackout. Alcohol is a central nervous system depressant, meaning it affects brain function and neural activity. One of its most severe effects, especially when consumed in large quantities, is causing a blackout—a temporary period where a person is unable to form new memories. Understanding the biology behind an alcohol ...
