Influence of the experience of the ultrasound examiner on diagnosis

Pathological changes	Ultrasound examiner with moderate experience (%)	Ultrasound examiner with high experience (%)
MRI found more lesions than ultrasound
Stenosis (n = 72)	62	38
Abscess (n = 16)	46	46
Fistula (n = 32)	59	41
Ultrasound found more lesions than MRI
Stenosis (n = 8)	0	100
Abscess (n = 4)	50	50
Fistula (n = 2)	0	100

The percentage indicates the ratio of moderate or experienced ultrasound examiners in this scenario. MRI: Magnetic resonance imaging.
