Imaging of ballistic wounds, bullet composition and implications for MRI safety — ScienceDaily

According to an article in ARRS’ American Journal of Roentgenology (AJR), because patients with ballistic embedded fragments are frequently denied MRI (due to indeterminate bullet composition sans shell casings), radiography and CT can be used to identify nonferromagnetic projectiles that are safe for MRI. “Commercially available handgun and shotgun ammunition representing projectiles commonly encountered in […]

This weird Cretaceous amphibian has the oldest-recorded ballistic tongue

A color-coded CT scan of the albanerpetontid specimen gives us hints at what this ancient creature looked like and how it’s sling-shot tongue works. (Edward Stanley/Florida Museum of Natural History/VGStudioMax3.4/) What has scales, claws, and looks like a lizard? Well, strangely enough, it seems one group of strange ancient amphibians did. While these animals, albanerpetontids […]
