Final answer:
The statement that MRI images have better resolution than CT scans is true, particularly for soft tissue. MRI's advanced capabilities include better soft tissue contrast and the ability to observe functional activity over time, such as with fMRI.
Step-by-step explanation:
Is MRI Imaging Resolution Better Than CT Scan?
The statement that MRI (Magnetic Resonance Imaging) images have better resolution than CT (Computerized Tomography) scans is true. MRI technology uses a magnetic field and radio waves to create detailed images of the body's internal structures. Unlike CT scans, which use X-rays, MRIs can differentiate between soft tissues with great precision, making it superior for certain types of tissue imaging. While CT is often better for visualizing bone fractures and is generally faster and more accessible, MRI provides superior soft tissue contrast and detail, especially useful in neurological, musculoskeletal, cardiovascular, and oncological imaging.
Moreover, MRI techniques such as functional MRI (fMRI) allow for the observation of brain activity over time. Combining this with the high-resolution structural images makes MRI not only better in terms of resolution but also invaluable for certain types of functional studies. While there are some constraints, such as the longer time needed for the procedure and issues with claustrophobic patients, the tip towards MRI's favor is clear when it comes to resolution and soft tissue differentiation. Newer open-MRI machines mitigate some discomfort by not enclosing the patient completely.
