Low Osmolality Contrast Media (LOCM) is characterized by being less viscous and thinner than High Osmolality Contrast Media (HOCM). This decreased viscosity is significant because a thinner contrast agent is easier to inject into patients, leading to smoother administration during procedures such as CT scans. Additionally, the lower viscosity enhances the distribution of the contrast media within the vascular system, allowing for improved imaging quality.

In comparison to high osmolality agents, which tend to be thicker and can create more resistance during injection, low osmolality agents provide benefits not only in terms of ease of use but also in patient comfort and safety. Typically, LOCM is associated with fewer adverse effects and lower levels of toxicity, making it a preferred choice in many imaging scenarios.

The other characteristics mentioned, such as thicker consistency, higher toxicity, or requiring a higher dose, do not apply to low osmolality contrast media. They define the properties of high osmolality contrast agents, which can lead to increased risk of side effects and complications during imaging procedures.
