Hey, kiddo, it's what's INSIDE that matters -- like your guts and bones and squishy brain and intestines and stuff. Meet Dr. Varshana Gurusamy: diagnostic radiology resident, Texan and amazing person with great stories. You'll learn the difference between an MRI and an ultrasound, between a CT scan and a CAT scan and why you should not put big things in orifices that you might not be able to retrieve them unaided. You'll want to hug a radiologist ... as soon as they take their lead gonad shield off.
