Forensic science is getting a makeover, and it's all thanks to something as small as a drop of blood. Dried Blood Spot (DBS) cards are becoming the talk of the town, especially in toxicology. These little cards are not just easy to use but also super efficient. Scientists have been working hard to make them even better. They wanted to see if they could use DBS cards ...
Deep brain stimulation (DBS) is a fancy term for a procedure that involves implanting electrodes in the brain. These electrodes send electrical signals to specific areas. This is done to help with various conditions, including dementia. However, the ethical and clinical risks tied to earlier DBS studies for dementia treatment are worth a closer look. Dementia is a t...
Deep brain stimulation (DBS) implants can heat up during MRI scans due to radiofrequency (RF). This makes imaging challenging. Researchers experimented with a method called "RF-shimming parallel transmission" (PTX) to tackle this issue. The key lies in accurately mapping the RF transmission field (B1+). However, these maps can have areas with low signals far from the...
