Introduction:

Medical imaging plays a critical role in modern healthcare, aiding in the accurate diagnosis and
treatment of various medical conditions. Magnetic Resonance Imaging (MRI) and Computed

Tomography (CT) scan are two prominent imaging modalities that have undergone significant
advancements in recent years. This article explores the emerging trends in MRI and CT scan

technology, highlighting the innovative techniques and tools that are revolutionizing the field of

diagnostic imaging.

Advancements in MRI Technology:

a. Ultra-High Field MRI: MRI scanners with higher magnetic field strengths, such as 3 Tesla (T)
and 7T, have become increasingly available. These ultra-high field MRI systems offer enhanced

signal-to-noise ratio and spatial resolution, enabling improved visualization of anatomical

structures and pathology. They are particularly beneficial in neuroimaging, musculoskeletal
imaging, and research applications.

b. Functional MRI (fMRI): fMRI is a technique that measures and maps brain activity by detecting
changes in blood flow. Recent advancements in fMRI have led to improved spatial and temporal

resolution, allowing for more precise mapping of brain functions. fMRI is widely used in research

studies and clinical applications, including preoperative mapping, evaluation of brain disorders,
and cognitive neuroscience.

c. Diffusion Tensor Imaging (DTI): DTI is an MRI technique that measures the diffusion of water
molecules in tissues, providing information about the integrity and organization of white matter

tracts in the brain. DTI has gained prominence in neuroimaging, enabling the assessment of brain
connectivity and investigating conditions such as traumatic brain injury, multiple sclerosis, and

stroke.
