The primary concern when using ionizing radiation in imaging is the risk of radiation exposure. Ionizing radiation has enough energy to ionize atoms and molecules, potentially leading to cellular damage and increasing the risk of cancer in patients over time. This risk is particularly significant because the effects of radiation are cumulative; even low doses can add up with multiple imaging studies.

Given the nature of diagnostic imaging modalities that rely on ionizing radiation, such as X-rays and CT scans, medical professionals must balance the need for clear and accurate imaging against the potential harmful effects of radiation exposure. The principle of "as low as reasonably achievable" (ALARA) is applied to minimize radiation doses while still obtaining diagnostic information. This concern is paramount because protecting patients from unnecessary or excessive radiation exposure aligns with the commitment to patient safety and care in medical imaging.

Other factors, like physical discomfort during an imaging procedure, the potential financial costs, and the duration of the imaging, while relevant in certain contexts, do not carry the same weight in terms of immediate health risks as the potential dangers posed by ionizing radiation.
