    "abstract": "Pulmonary embolism (PE) can be fatal yet difficult to diagnose in pregnancy. Computed tomography pulmonary angiogram (CTPA) or ventilation/perfusion (V/Q) scans are often conducted, potentially leading to low positive scan rates.\nRetrospective data analysis was conducted for pregnant women and non-pregnant age-matched control who underwent CTPA and/or V/Q scan for investigation of PE. The main outcomes were the positive and non-diagnostic imaging rates.\nIn total, 440 women underwent V/Q or CTPA scans, 86 of whom were pregnant (19.5%). The positive scan rate was 3.5% and 8.8% in the pregnant and non-pregnant groups, respectively (\nOur study confirms a low positive imaging rate and a relatively high non-diagnostic CTPA rate in pregnancy. Newer strategies are needed to reduce the number of negative imaging studies conducted.",
