Ultrasound Anatomy & Normal Appearance: A Practical Approach: This book will be a necessary download for all practicing ultrasound operators. I feel like this book is overpriced for the crappy images it shows I just received my copy today and after paying almost $, I expected great quality images.

We then expand upon examination techniques relevant to different segments of and structures around the intestine, including an overview of transperineal ultrasonography.
We describe specific intestinal luminal parameters to be assessed in GIUS including special techniques such as contrast-enhanced ultrasound. As the gut grows and returns into the peritoneal cavity, it eventually rotates degrees counter-clockwise, such that the duodenum rests behind the SMA[ 1 ].
The caecum, initially in the upper abdomen, descends to the right lower quadrant. Thus the mesentery attachment of the small bowel takes an oblique course from the duodeno-jejunal junction at the level of the left L2 process, over the 3rd part of the duodenum, down to the level of the right sacroiliac joint[ 5 ].
Though the mesentery attachment is only cm long, it supplies a length of small intestine approximately 40 times its length, a feat achieved through progressive fan-like ruffles. Seen with traditional barium enterography, each curve of the intestine has a concave and convex aspect, the concave generally pointing towards the mesentery whilst the convex aspect representing the anti-mesenteric border[ 6 ]. These can be viewed in real time with GIUS. Towards the end of the first trimester, the peritoneum of the newly forming ascending colon and the hind-gut derived left colonic segments, begin to fuse with the posterior abdominal wall.
Although traditionally described as retroperitoneal structures, modern post-mortem studies have found that two thirds of the ascending and a third of the descending colonic segments have mobile portions of elongated mesentery[ 7 ].
Nonetheless, peritoneal attachments have significance for the flow of free fluid within the abdomen as fluid tends to flow caudally, medial to the ascending colon towards the ileocaecal junction and thus metastatic deposits may become lodged in the mesenteric ruffles en route.
Relative thickenings of the mesocolon provide ligamental support to the colonic flexures; the nephrocolic ligament runs from the inferior aspect of the right kidney to the hepatic flexure which then becomes intimately related to the descending duodenum before the transverse mesocolon begins; the splenic flexure is suspended by 1 the phrenicocolic ligament which runs from the diaphragm and also supports the spleen; 2 the splenocolic; and 3 the pancreaticocolic ligaments which are essentially extensions of the transverse mesocolon[ 5 , 7 ].
These attachments provide fixed points for ultrasound evaluation of the colon, which can at times, be highly mobile within the abdomen.
The taenia coli, thickenings of the longitudinal muscle layer grow from diffuse sheets at the caudal end of the bowel, become more defined in the proximal colon until they encase the caecum[ 6 ]. The taeniae are one sixth shorter than the colon[ 5 ], forming the haustrae. The muscle fibres in the longitudinal layer end by turning at right angles to merge with the circular fibres and thereby acting as fixed linkage points for contraction.
Contractions can occur asymmetrically obliterating some haustrae, giving the false impression of small-bowel-like semi-circular folds and bowel wall thickening. Vascular supply of the colon flows from the mesenteric border, vessels spreading around the colon.
The vasa recta penetrate through oblique connective tissue clefts in the bowel wall, the site of diverticular protrusion, but importantly enter these clefts on the anti-mesenteric aspect.
In practice, diverticula are rare on the anti-mesenteric border between the taenia omonetalis and taenia libera.
A vasa recta vessel runs over the long aspect of each diverticulum before entering the submucosa at the antimesenteric border[ 6 ]. Prior cross-sectional imaging and endoscopy reports should be available to inform of post-surgical and anatomical variants.
In most scenarios patient preparation is not required but specific measures can be used. Fasting for h decreases bowel motility whilst two cups of water can be used to improve visualisation of the duodenum[ 8 ]. Free delivery worldwide.

Popular Features. New Releases. Pre-clinical Medicine: Ultrasound Anatomy of Lower Limb Muscles: Description The book provides a comprehensive description of the basic ultrasound principles, normal anatomy of the lower limb muscles and classification of muscle strain injuries. Ultrasound images are coupled with anatomical schemes explaining probe positioning and scanning technique for the various muscles of the thigh and leg.
For each muscle, a brief explanation of normal anatomy is also provided, together with a list of tricks and tips and advice on how to perform the ultrasound scan in clinical practice. This book is an excellent practical teaching guide for beginners and a useful reference for more experienced sonographers.
