[The omitted x-ray examination--benefit and risk--a comparison]

Area of Science:

• Radiology
• Medical Imaging
• Diagnostic Procedures

Background:

• The risk of omitting X-ray examinations is often underestimated compared to the stochastic risks of radiation exposure.
• The benefit of X-ray examinations is determined by their impact on diagnostic decisions and therapeutic strategies.
• Unnecessary X-rays are performed, yet routine examinations can yield critical findings.

Purpose of the Study:

• To compare the benefit of X-ray examinations against the assumed risks of radiation exposure.
• To emphasize the importance of proper justification and indication for X-ray procedures.
• To highlight the potential dangers of omitting indicated X-ray examinations.

Main Methods:

• Benefit assessment based on influence on diagnostic decisions and therapy.
• Evaluation of three degrees of justification (indication) for X-ray examinations.
• Comparison of benefit versus assumed irradiation risk, exemplified by thorax and lumbar spine imaging.

Main Results:

• Estimated benefit of X-ray examinations exceeds assumed irradiation risk by several orders of magnitude.
• Guidelines for quality assurance in X-ray diagnostics and CT significantly reduce patient doses.
• Even routine X-rays can provide therapeutically relevant findings in certain patients.

Conclusions:

• X-ray examinations offer substantial benefits that far outweigh radiation risks when properly indicated.
• Critical evaluation of indications and minimized radiation exposure are crucial for optimal X-ray utilization.
• Withholding indicated X-ray examinations poses a greater danger to patients than the associated radiation risk.
