Although not all clinicians will want to revert to scanning for all patients with suspected PE, there are clinical scenarios where it should be considered as the imaging test of choice. These scenarios include patients with a normal baseline chest radiograph (in which the likelihood of a diagnostic scan is high), young women, patients with a contrast dye allergy or impaired renal function, and patients who are claustrophobic and may not tolerate (or are obese and cannot be accommodated by) the CT scanner. scanning also may offer the advantage of a test that can be repeated in follow-up to monitor for resolution. Further, in most settings, it is less costly than CTPA. We need to resist the temptation to get as much information as possible and focus instead on carefully selecting the test that will answer the question at hand. scintigraphy, therefore, clearly still has a role in the diagnostic evaluation of acute PE, and I thank Salaun and colleagues for confirming that this approach is safe for our patients.
