Higher patient doses through X-ray imaging procedures.

Area of Science:

• Medical Imaging
• Radiology
• Radiation Safety

Background:

• X-ray imaging has been a cornerstone of medical diagnostics for over a century.
• While beneficial, X-ray procedures, particularly computed tomography (CT) and fluoroscopy, carry significant radiation risks.
• Cumulative radiation doses exceeding 100 mSv from multiple procedures are becoming a growing concern.

Purpose of the Study:

• To highlight the escalating radiation dose concerns in medical imaging.
• To emphasize the need for technological advancements and optimized usage to reduce patient exposure.
• To explore future innovations for dose reduction in X-ray-based imaging.

Main Methods:

• Review of current trends in medical imaging radiation doses.
• Analysis of technological advancements and their impact on radiation exposure.
• Discussion of emerging technologies like monochromatic X-ray sources and robotic systems.

Main Results:

• Despite technological progress, radiation doses in some procedures have increased due to the pursuit of better diagnostic information.
• Cumulative doses from repeated procedures pose a significant health risk.
• New technologies, such as monochromatic X-ray sources, hold promise for substantial dose reduction across all X-ray imaging modalities.

Conclusions:

• There is an urgent need for manufacturers to develop lower-dose equipment, especially CT scanners capable of sub-mSv doses.
• Implementation of dose optimization strategies by users is critical.
• While robotic systems may reduce operator exposure, patient dose reduction remains a key challenge requiring further innovation and emphasis on training.
