In this paper, we compared and analyzed three different methods of classification of dementia from brain magnetic resonance imaging (MRI). The first method was K- Nearest-Neighbors (k-NN), a technique that compares the test sample to the k nearest points and assigns a class based on the ...

When you are comfortably positioned, the table will slowly move into the magnetic field. The technologist will stay in constant contact with you. You can listen to music on a stereo system during your testing. As the exam proceeds, you will hear a muffled "thumping" sound for several minutes...
因此,我们只使用在特征选择后训练的模型来比较发现队列中的模型性能并在外部测试集中验证它们。 Figure 4: Heat maps of areas under the receiver operating characteristic curve from various machine learning models to predict Parkinson...

MRI exams of the brain using diffusion tensor imaging (DTI) are a promising option for analysis of dementia risk. These exams assess the condition of the brain's white matter. "With DTI you look at the movement of water molecules along white matter tracts, the telephone cables of brain," ...

ASL MRI has potential as a standalone test or as an adjunct to PET for dementia screening, Dr. Haller said. While PET can identify markers of Alzheimer's disease in thebrainand cerebrospinal fluid, it exposes the patient to radiation. ASL does not expose the patient to radiation and is eas...
Participants were also excluded from the present analysis if they reported having received a diagnosis of dementia, parkinson’s disease, multiple sclerosis, epilepsy, stroke, head or neurological injury, trauma, or other chronic neurological problems (nervous system infection, brain abscess, encephalitis...
It is classified as a brain disease causing dementia that presents with memory loss and cognitive impairment. Experts primarily use brain imaging and other tests to rule out the disease. To automatically detect Alzheimer's patients from healthy controls, this study adopts the vision transformer ...
