If the acquisition parameters and timing of the contrast bolus are optimised, this resolution even allows visualisation of a tiny artery.6,7 In classical anatomical arterial pattern, coeliac axis gives rise to left gastric artery (LGA) and then bifurcates into splenic artery and common hepatic ar...
A better approach to the diagnosis of PE: A simple diagnostic algorithm is all that's needed to safely and effectively reduce our reliance on CT pulmonary angiography to diagnose PE Several techniques are currently available for decreasing the contrast dose for CTPA. Scanning at a lower tube pote...
However, the tool needs further evaluation in implementation studies before it is ready for “prime time”. Traditional methods of working up a SAH has been non-contrast CT followed by a lumbar puncture (LP). Dr. David Newman has questioned this dogma on his SMART-EM podcast. He su...
When imaging is obtained, it is most useful to exclude other causes of PPH as the imaging findings of uterine atony overlap with other causes of hemorrhage. Imaging with CTA can also help confirm whether or not there is active hemorrhage. The accuracy for detecting contrast extravasation via ...
