ADVANCED DIAGNOSTIC TECHNOLOGY FOR BRAIN

Gayatri Kalkul and Dinesh Kumar Jain*

ABSTRACT

The quick development of diagnostic technology has fundamentally altered the field of medicine by allowing accurate and thorough evaluation of numerous physiological and pathological problems. This review article examines the crucial contribution that cutting edge diagnostic tools have made to the field of medicine, including Single photon emission computed tomography (SPECT), Positron emission tomography (PET), Magnetic resonance spectroscopy (MRS), Diffusion-weighted imaging (DWI), and Electroencephalography (EEG). We dig into the fundamentals and uses of each technology, emphasizing how they help to reveal the chemical, structural, and functional details of the human body and brain. Early disease detection and individualized treatment plan are now possible because to the development of powerful techniques like SPECT and PET for imaging metabolic processes and molecular interactions. We now have a better understanding of a variety of illness thanks to MRS’s non- invasive insights into tissue composition and metabolic processes. In particular in neurological circumstances, DWI has played a significant role in measuring microstructural integrity and has also provided novel insights on tissue damage and recovery. EEG, on the other hand, has shaped our understanding of neural dynamics and neurological illness by providing vital real time data on brain activity and connectivity.
