Clinically not relevant, but interesting info from Dr Charles Lott's @EverlightRad webinar on dental imaging: if a tooth is moved too quickly by orthodontic treatment, it can result in 'root amputation' (resorption around the roots, yellow arrows in image)

@docskalski at #Radiopaedia2020: any degree of agenesis of the posterior arch of C1 will result in extra forces on the anterior part of C1 and you're likely to see resulting hypertrophy and sclerosis of the anterior arch of C1

@DrVikasShah at #Radiopaedia2020: non-irritant, water-soluble oral contrast is useful to demonstrate leaks or fistulae; the timing is dictated by the area of interest, e.g. give 100 ml on the CT table if you need to see the oesophagus or gastric pull-up #FOAMrad @FOAMed #radres

@DrElizabethDick in @EverlightRad webinar: transient osteoporosis and avascular necrosis can look the same on MRI. Follow-up imaging will help differentiate as transient osteoporosis is reversible. #FOAMrad #EmergencyRad #radres

@DrElizabethDick in @EverlightRad webinar: compartment syndrome is a clinical diagnosis, but imaging features include muscle compartment swelling and loss of normal muscle architecture. Describing the extent helps guide fasciotomy.

@DrAndrewDixon: you can detect active arterial bleeding on a portal venous CT. If the contrast is very dense, it's arterial. Conversely, it's difficult if not impossible to detect organ laceration on arterial phase scanning. @Radiopaedia #TraumaRad

@DrAndrewDixon: remember that the density of wood is closer to air than soft tissue. Always use lung window to double check that "subcutaneous air" #TraumaRad #radres #FOAMrad
