Bowel Wall Thickening on CT Scan Is a High Yield Colonoscopy Indication | | Wall thickening in the Lower GI tract (WTLGIT) commonly presents a challenge to clinicians as there is the concern for neoplasia. We hypothesize that majority of the patients that have thickening are unlikely to have significant findings on colonoscopy.

X-rays illuminate the interior of the Moon | | Unlike Earth, the moon has no active volcanoes. This is surprising as liquid magma is believed to exist deep inside the Moon. Scientists have now found that this hot, molten rock could actually be so dense that it is too heavy to rise to the surface. For this experiment, microscopic reproductions of... | | 2/19/2012 1:33:33 PM |
