MRI versus CT scans – the differences


Medical imaging has become a key part of diagnosis in modern medicine, with magnetic resonance imaging (MRI) and computed tomography (CT) being two of the most advanced imaging modalities. Despite some similarities, these techniques are different in many ways. What are the differences? Let us explain.


What does contrast enhancement in CT mean?


Contrast enhancement in computed tomography (CT) scans refers to a technique used during a CT scan whereby a contrast agent is administered to the patient, allowing certain structures in the patient’s body to become more clearly visible on CT images. How does this work in practice? What are the types of contrast agents and when are they used? Read on to find out more!


What are the principles underlying magnetic resonance diffusion-weighted imaging?


Diffusion-weighted imaging (DWI) is an innovative technique used in magnetic resonance imaging (MRI). It allows for an extremely accurate assessment of the movement of water molecules in tissues, which is crucial in diagnosing various brain disorders, but other conditions as well. If you want to learn what this examination consists of and when it is most often used, read on!


FLAIR sequence in MRI – what is it?


Magnetic resonance imaging (MRI) is one of the most important tools in medical diagnostic imaging. Importantly, this technology offers multiple possibilities in this regard due to the many different MRI sequences available during examinations. These include the FLAIR (Fluid-Attenuated Inversion Recovery) sequence, which is distinguished by its unique features. What exactly does the FLAIR sequence consist of and when is it applicable?


Magnetisation transfer imaging


Magnetisation transfer imaging (MTI) is among the latest tools in the field of medical imaging. Its primary advantage is that it allows extremely precise assessment of brain structures and functions. This article discusses, among other things, the exact nature and application of this type of diagnostics.
