anatomical delineation, and improved characterization of tissue pathology. Functional MRI

(fMRI): Functional MRI is a specialized technique that measures brain activity by detecting
changes in blood flow and oxygenation. Recent advancements in fMRI have expanded its

applications in studying brain function and mapping neural networks. Advanced fMRI methods,
such as resting-state fMRI and task-based fMRI, provide valuable insights into brain connectivity,

cognitive processes, and disease-related alterations. fMRI plays a crucial role in preoperative

planning, assessing neurological disorders, and monitoring treatment response in conditions like
stroke, epilepsy, and neurodegenerative diseases. Diffusion-Weighted Imaging (DWI): Diffusion-

weighted imaging measures the random motion of water molecules in tissues. It is sensitive to
changes in tissue microstructure and is commonly used in oncology, neurology, and

musculoskeletal imaging. Recent advancements in DWI techniques, such as high b-value imaging

and diffusion tensor imaging (DTI), have improved the quantification and visualization of tissue
diffusion characteristics. DWI helps in the detection and characterization of various pathologies,

including tumors, stroke, and inflammatory disorders. Magnetic Resonance Spectroscopy (MRS):
Magnetic Resonance Spectroscopy provides insights into the metabolic composition of tissues by

measuring the levels of various metabolites. Recent developments in MRS have led to improved
spectral resolution, sensitivity, and quantification methods. MRS aids in the assessment of brain

tumors, neurodegenerative diseases, and liver pathologies by providing information about tissue

metabolism and biochemical alterations. It plays a vital role in treatment planning, monitoring
therapeutic response, and evaluating disease progression. Multiparametric MRI: Multiparametric

MRI combines multiple MRI sequences and imaging parameters to obtain comprehensive
information about tissue structure, function, and metabolism. By integrating anatomical,

functional, and molecular data, multiparametric MRI improves diagnostic accuracy and enables

more precise treatment planning. It is widely used in prostate cancer imaging, breast imaging, and
liver imaging. Multiparametric MRI allows for better lesion detection, characterization, and

localization, facilitating personalized medicine and individualized treatment strategies. Artificial
Intelligence (AI) in MRI: The integration of AI techniques in MRI has the potential to transform

diagnostic imaging. AI algorithms can assist in image reconstruction, noise reduction, and image

analysis. Deep learning algorithms enable automated image segmentation, lesion detection, and
classification, enhancing efficiency and accuracy in radiological interpretation. AI-driven decision

support systems aid radiologists in making more accurate diagnoses, detecting subtle
