Thunderclap headache, but negative CT: now what?

A 45 year old male comes into the ED with a sudden, severe headache. It started while he was at work yesterday and was the worst of his life. It started feeling a little better, but hasn’t totally gone away and his wife made him come to get checked out. There are enough concerning features […]

Renal Colic & the CT scan: flip your patient prone!

A CT abd/pelvis without contrast is one of our go-to studies when evaluating for nephrolithiasis in a patient with acute flank pain.

Street Stats: The Bonferroni Correction
