The Ultrasound Working Group of the European Society of Radiology aims to highlight with these recommendations the importance of infection prevention and control in ultrasound.

Main messages:

• Transducers must be cleaned/disinfected before first use and after every examination.
• Low level disinfection is sufficient for standard US on intact skin.
• High level disinfection is mandatory for endo-cavity US and all interventions.
• Dedicated transducer covers must be used for endo-cavity US and all interventions.
• Sterile gel should be used for all endo-cavity US and all interventions.
