Ultrasound

Uses frequencies in the range of 2-10MHz. Waves are emitted by a transducer that also detects reflected waves  processed and displayed.
Most commonly used for soft tissue abnormalities eg Achilles tendon, posterior tibial tendon, peroneal tendons, flexor hallucis longus tendon, anterior tibial tendon, plantar fascia, ganglia, Mortons neuroma

(talk mark gilheany’s radiologist re plantar plate ruptures)

Advantages:
• not ionising radiation
• relatively low cost (compared to MRI and CT)
• can perform dynamic scanning
• portable equipment
• harmless to patient

Disadvantages:
• high reliance on skill of operator (significant learning curve for musculoskeletal imaging)
