The resistive index (RI) is a measurement of arteriole vascular resistance and is obtained by pulsedwave Doppler interrogation. The diagnostic potential of the renal resistive index (RI) was retrospectively investigated in 142 kidneys from 81 dogs. The resistive index of each kidney was compared to clinical laboratory parameters, clinical diagnoses, and sonographic findings. The mean renal resistive index (RI) for 22 normal kidneys was 0.61 (standard deviation = 0.06). An elevation in the mean renal RI (>0.70) was found for the clinical diagnoses of acute renal failure and congenital dysplasia. When a RI of greater than 0.70 was considered abnormal, the sensitivity and specificity of the RI in determining normal vs. abnormal kidneys were 38% and 96% respectively.

The head from three horses euthanized due to diseases unrelated to the head and neck was imaged using computed tomography (CT). Gross cross-sectional slices of equine head #1 and skeleton of equine head #2 were compared with the CT images of the three equine heads to identify normal structures of the cranium, brain, paranasal sinuses, nasal cavity, and teeth. Labeled transverse CT images of the equine head are presented sequentially as a reference for normal anatomy.

This article is the sixth in a series of seven describing the journey within NHS Lanarkshire in partnership with the University of the West of Scotland to support nursing and midwifery leadership roles through Scotland's Leading Better Care programme. Preceding articles have provided an overview of the programme and discussed a range of staff development work programmes. This article describes work carried out on clinical documentation to promote delivery of the three quality ambitions of safe, effective and person-centred care.
