I love it when you guys talk dirty.A lot of imaging centers can't tell the difference between non-obstructive intra-renal calculi and post inflammatory fibrotic changes from previous high urinary tract infection. Have seen several pilots get screwed on this, luckily all it takes is a non-contrast CT scan to clear them ... ultrasound with a low experienced recent graduate sonographer can cause some big problems ...
Which one of those is disqualifying?
