INTRODUCTION
The medial iliac lymph node (MILN) and jejunal lymph node (JJLN) generally become hypoechoic, enlarged and detectable when inflamed or infiltrated secondary to reactive hyperplasia in animals.

INTRODUCTION
Although the abnormalities of the 4th ventricle are highly described using MRI technique in dogs, the normal dimensions are still not well defined.
OBJECTIVES
Defining the normal shape and area of the 4th ventricle, establish a new angle in normal canine brains and finding out the effect of head phenotype and body-weight on these parameters.
METHODS
This work was achieved in the Small Animal Hospital/ Glasgow University in 2014. 32 dogs of different breeds were included had age range (1.1- 11.1) years and body- weight (7 -42) kg. The area of the 4th ventricle defined on midline sagittal plane dorsally by the base of the cerebellum, ventrally by the brainstem, anteriorly by the mesencephalic aqueduct and by the central canal of the spinal cord caudally; its length was defined as the longest line of that area. The area of the cranial cavity was also measured. An angle was defined for the first time and named as the 4th ventricle angle.
RESULTS
The 4th ventricle was divided into three parts: rostral, middle and caudal parts in which the rostral and caudal parts had a narrow path like while, the middle has wider area. Furthermore, the rostral and caudal parts were characterized by lower signal intensity comparing to the middle part.
CONCLUSIONS
Normal shape and dimensions of the 4th ventricle can
be well delineated using midline sagittal plane of T2 weighted MRI and the signal intensity of its parts is well demarcated. Finally, the created angle appeared to be in correlation to the head phenotype.
    To standardise the dimensions of MILN and JJLN in apparently healthy dogs, to record the ultrasonographic features of these nodes and to correlate the dimensions of lymph nodes with age, body weight and body condition score (BCS).
METHODS
Ultrasonographic features and biometry were recorded in thirty apparently healthy dogs using LogiQ F8 machine.The observed data was statistically analysed
to obtain means, 95% confidence intervals of the mean, standard error, minimum and maximum, correlations
and ANOVA to compare the means based on age, body weight and BCS. The Pearson correlation coefficient, Beta coefficients and SEs obtained from univariate linear regression were also calculated.
RESULTS
The length and height of MILN ranged from 0.63-3.75 cm and 0.23-1.27 cm for left node and 0.78-3.98 cm and 0.21-1.03 cm for right node respectively. The length and height of JJLN was 0.21-4.12 cm and 0.26-1.24
cm respectively. The dimensions of the MILN showed significant correlations with age and body weight of the dog. However, BCS had no correlation with the dimensions of MILN. The dimensions of JJLN had no correlation with age, body weight and BCS.
CONCLUSIONS
Ultrasonographic biometry of MILN & JJLN for apparently healthy dogs was standardised. This can be used as a baseline data for evaluation of these nodes in dogs.The alterations in the sonographic features can be used to differentiate between normal and diseased nodes
