My co-authors and I just published a new paper:
Toney LK, Lewis DH, Richardson ML. Ventilation/Perfusion scanning for acute pulmonary embolism: effect of direct communication on patient treatment outcomes. Clin Nucl Med. 2013 Mar;38(3):183-7.
Spoiler alert: direct verbal communication of V/Q results between the nuclear medicine physician and the referring clinician results in a higher rate of treatment, regardless of the outcome of the V/Q scan.
