This week's #xrayofthweek is a video clip showing peristalsis of the small bowel on MRI. I use this cine sequence routinely in my small bowel MRI studies to evaluate for normal and abnormal motion of the small bowel - segments which are narrowed and fixed due to stricture formation do not peristalse well and stand out. This particular clip shows peristalsis of normal small bowel.
I have detailed the methods used to acquire this sequence in this Radiopaedia case. In future #xrayoftheweek posts, I will describe other innovative MRI sequences I have developed and use in my day-to-day GI imaging practice.
The latest #xrayoftheweek is one for medical students/junior doctors/radiographers. What can you see on the chest xray of this person who presented with progressive shortness of breath and a cough over the previous 2 weeks?
