  Hepatic encephalopathy is caused by liver dysfunction resulting in buildup of toxic substances in the blood, which can affect brain function. Common causes of liver dysfunction include: Cirrhosis (scarring) of the liver Acute liver failure Chronic liver disease Hepatitis (viral liver inflammation) Excessive alcohol consumption Toxins or medications that damage the liver Portosystemic shunting (bypass of blood around liver) Electrolyte imbalances, such as high levels of ammonia.

how kidney produces ammonia? Kidneys produce ammonia as a byproduct of nitrogen metabolism in the urea cycle. The urea cycle takes place in the liver and the kidneys, and converts excess nitrogen into urea, which is then excreted in the urine. During this process, some nitrogen is converted into ammonia and used as a source of energy by the cells. Ammonia is toxic in high concentrations, so it is quickly converted into urea and excreted from the body.

 Diffusion tensor imaging (DTMRI)  explained Diffusion Tensor Imaging (DTI) is a type of MRI scan that uses the diffusion of water molecules in the brain to create images of the brain's white matter tracts. White matter tracts are made up of long, thin nerve fibers that carry information between different parts of the brain. DTI allows us to see these tracts in detail and can be used to study brain disorders and injuries that affect white matter, such as multiple sclerosis or traumatic brain injury. DTI is based on the principle of diffusion, which is the random movement of water molecules in the body. By measuring the diffusion of water molecules in different directions, DTI can create maps of the brain's white matter tracts and identify any disruptions or abnormalities in those tracts. This technique can provide valuable information about the structure and integrity of the white matter in the brain, which is important for understanding the brain's function and connectivit...

Functional mri explained | fmri Functional MRI (fMRI) is a type of MRI scan that uses blood flow to indicate which parts of the brain are active. It works by measuring changes in the oxygen levels in blood flowing through the brain, which increase in areas where neural activity is taking place. This is done by injecting a contrast agent into the bloodstream, which makes the blood in active areas appear bright on the scan. fMRI is commonly used in research to map brain activity and can be used to diagnose brain disorders and injuries, as well as to study brain function in various cognitive and behavioral tasks.

 Ultrasound imaging in biomedical explained Ultrasound imaging, also known as ultrasound scanning or sonography, is a medical imaging technique that uses high-frequency sound waves to create images of internal organs, blood vessels, and other structures inside the body. Ultrasound is a non-invasive and painless procedure that is often used to diagnose and monitor pregnancy, as well as to evaluate organs and structures such as the liver, gallbladder, pancreas, and kidneys. The basic concept of ultrasound imaging is to use high-frequency sound waves to create images of internal structures. A small transducer, or probe, is placed on the surface of the skin and sends out sound waves that penetrate the body. The sound waves then bounce back off internal structures and are received by the transducer. The transducer then sends this information to a computer, which creates an image of the internal structures. There are different types of ultrasound imaging, including traditional 2D ultraso...

 CT or computed tomography explained Computed Tomography (CT) is a medical imaging technique that uses X-rays and computer technology to create detailed cross-sectional images of internal organs, bones, and other tissues. CT scans are often used to diagnose diseases and injuries, and to monitor the progression of treatment. The basic concept of CT is to take a series of X-ray images from different angles around the body and then use a computer to combine them into a detailed 3D image. CT scans work by using X-ray beams to penetrate the body and create an image of the internal structures. The X-ray beam is emitted from a circular tube called an X-ray source and is directed at the body part being scanned. The X-ray beam passes through the body and is detected by an array of detectors on the opposite side. The CT scanner takes multiple X-ray images, each at a slightly different angle, while the patient is moved through the machine. The computer then combines these images to create a d...

 MRI Concept explained easily Magnetic Resonance Imaging (MRI) is a non-invasive imaging technique that uses a powerful magnetic field, radiofrequency waves, and a computer to produce detailed images of internal organs, soft tissues, and bones. MRI allows doctors to visualize the internal structures of the body without the need for X-rays or other ionizing radiation, making it a safe alternative for many diagnostic and therapeutic applications. The basic concept of MRI is based on the fact that the nuclei of certain atoms, such as hydrogen, have a property called "spin" which can be manipulated by a magnetic field. When exposed to a strong magnetic field, the hydrogen nuclei align themselves with the magnetic field. Then, a radiofrequency (RF) pulse is applied, which causes the nuclei to rotate out of alignment with the magnetic field. When the RF pulse is turned off, the nuclei relax back to their original alignment, and this process generates a small electrical signal that ...
