Evaluation of normal findings using a detailed and focused technique for transcutaneous abdominal ultrasonography in the horse

Table 3 Identification sites and repeatability of identification (%) of abdominal structures, imaged using a single focused ultrasound examination in 20 normal horses (total of 20 examinations).

	Repeatability of identification (%) at each individual imaging site*
Abdominal structure	Right caudo-dorsal flank	Right cranio- dorsal flank	Left caudo-dorsal flank	Cranio-ventral abdomen	Caudo-ventral abdomen	Repeatability of identification of structure across complete examination (examinations identified / total number of examinations)**
Duodenum	30	0	0	0	0	30% (6/20)
Other small intestine	0	0	0	35	10.5	45.5% (9/20)
Caecum	85	0	0	0	0	85% (17/20)
Sacculated large intestine	15	100	90	100	100	100% (20/20)
Right kidney	100	0	0	0	0	100% (20/20)
Left kidney	0	0	90	0	0	90% (18/20)
Liver	0	95	0	0	0	95% (19/20)
Spleen	0	0	80	0	0	80% (16/20)

*The repeatability of identification (%) at each individual imaging site describes how often each abdominal structure was identified at each separate imaging site (across all 20 examinations (20 horses examined once)), i.e. where can you find this structure on ultrasonographic examination?
** The repeatability of identification across complete examination describes how often each abdominal structure was identified at any site during each examination (total of 20 examinations (20 horses examined once)), i.e. how often can you find this structure on ultrasonographic examination of the whole abdomen?
The site where each structure was most repeatedly identified, termed the ‘best imaging site’ is highlighted in bold.
