Low Dose CT Scans: A Safer Alternative

Low Dose CT

Low Dose Computed Tomography (CT) scans represent a significant advancement in medical imaging, offering detailed internal views with a fraction of the radiation exposure traditionally associated with CT scans. This innovation is particularly important in managing patient safety while ensuring diagnostic accuracy.

Conventional CT scans, while effective, expose patients to relatively high levels of ionising radiation, which can increase the risk of cancer over time. Low Dose CT, however, utilises advanced technology to significantly reduce this exposure—by up to 90% in some cases—without compromising the quality of the images produced. This reduction is achieved through sophisticated software algorithms that enhance the image quality from fewer or lower-intensity X-ray beams.

The implications for patient care are profound, especially in monitoring conditions that require multiple scans over time, such as lung nodules or other chronic conditions. Low Dose CT is particularly pivotal in screening programmes, like those for lung cancer detection in high-risk populations (e.g., long-term smokers). Studies have shown that using Low Dose CT for lung cancer screening can reduce mortality rates by detecting cancers at a much earlier, more treatable stage.

Furthermore, the reduced risk associated with Low Dose CT makes it a more viable option for paediatric patients, for whom radiation exposure is a significant concern. Children are more sensitive to radiation and more likely to experience its harmful effects later in life, making the lower dose approach invaluable.

As technology progresses, the potential for Low Dose CT to include even broader applications grows, promising to reshape diagnostic strategies across various fields of medicine, thereby improving outcomes while safeguarding patient health.
