The imaging systems and protocols used during ventilation-perfusion lung (V-P) scintigraphy and computed tomographic (CT) pulmonary angiography (CTPA) can affect diagnostic performance. We investigated the level of awareness of these factors among US clinicians who refer patients for imaging for suspected acute pulmonary embolism. ⋯ Although state-of-the-art equipment is important to them, clinicians practicing in the United States have limited knowledge of the equipment being used during CTPA and V-P scintigraphy scanning in their communities. Radiologists should intensify efforts to familiarize their clinical colleagues with the equipment they use.
