A selection of videos showcasing some of the cool stuff we can do with diagnostic imaging these days.


Sagittal FLAIR (fluid attenuation inversion recovery) MRI brain in a patient with multiple sclerosis showing multiple hyperintense demyelination plaques in a typical distribution in the corpus callosum and the periventricular and pericallosal white matter.


This video is from a ‘virtual colonoscopy’, created from a CT colonography study.


Water soluble iodinated contrast study in a patient who presented with chest pain and a chest x-ray that showed extensive pneumomediastinum following an episode of vomiting. The presumed source of the pneumomediastinum was the oesophagus, therefore a contrast study was requested to assess for a perforation. Barium would be unsafe in this situation as if it leaks from the oesophageal tear it will cause mediastinitis, which can be fatal. At the beginning of the video you will see the pneumomediastinum labelled. No oesophageal tear was identified.


Coronal CT images of the abdomen from a patient who was admitted hypotensive after a road traffic accident. Note the abnormal appearance of the spleen, which is due to an extensive splenic laceration. There is free fluid in the peritoneal cavity, which is higher density than simple fluid indicating that it represents blood.


Reconstructed CT images of the lumbar spine in a patient who fell from a height and landed on her feet. This shows a compression fracture of L3.


Cardiac MRI showing a grossly thickened interventricular septum in this patient with hypertrophic cardiomyopathy. Case courtesy of Prof J Dodd, SVUH.

This video has been made from dynamic MR images of the pelvis taken from a pregnant patient with possible appendicitis and shows the fetus moving around and kicking – the noise generated by the magnet during image acquisition often causes the fetus to go little crazy!

This is a 3D reconstruction of a CT showing a comminuted fracture of the left iliac bone.

Another 3D CT reconstruction, in this case showing dislocation of the elbow. The radial head is no longer articulating with the humerus; the olecranon of the ulna is still in contact with the humerus but has shifted laterally and is articulating with the capittelum rather than the trochlea.
