Radiology Technology Qualification (China) - independent subject foundations common mistakes
Radiology Technology Qualification (China) - independent subject foundations · Understand the traps and how to avoid them.
Equating display brightness with patient dose
Digital processing can produce similar appearances across different acquisition exposures.
What to do instead
Review appropriate acquisition indicators and the diagnostic task.
Applying worker dose limits directly to patient care
Medical exposure has a different justification and optimization framework.
What to do instead
Use the actual patient risk-benefit process and relevant protection requirements.
Forcing a routine trauma position
Movement can be unsafe when injury or instability is possible.
What to do instead
Assess the patient and use the appropriate adapted procedure.
Treating every implant as universally safe or universally forbidden
The exact device, conditions and responsible assessment matter.
What to do instead
Verify the relevant information and follow the qualified MR safety process.
Stopping metformin for every contrast study by default
The actual route, renal context and guidance affect the decision.
What to do instead
Use current individualized clinical guidance without an unqualified medication order.
Calling all bright diffusion signal restricted diffusion
T2 contribution and other factors can influence the appearance.
What to do instead
Review ADC and the rest of the relevant examination.
Assuming pitch always changes dose by a fixed proportion
Output control and other acquisition parameters can change the relationship.
What to do instead
Specify held-constant variables and the actual scanner behavior.
Using a processing effect to recover missing anatomy
Display and edge processing cannot recreate information not adequately acquired.
What to do instead
Identify the original limitation and decide what action the clinical task requires.
