04/01/2014 - "CT pulmonary angiography (CTPA) is considered the gold standard for the diagnosis of pulmonary embolism (PE) and is frequently performed in patients with cardiopulmonary complaints. "
01/01/2014 - "Computed tomographic pulmonary angiography (CTPA) is a gold standard test for the diagnosis of pulmonary embolism (PE), but is reported to be over prescribed. "
12/01/2012 - "Computed tomography pulmonary angiography (CTPA) is considered as clinical gold standard for diagnosing pulmonary embolism (PE). "
08/01/2012 - "To identify reasons for ordering computed tomography pulmonary angiography (CTPA), to identify the frequency of reasons for CTPA reflecting defensive behavior and evidence-based behavior, and to identify the impact of defensive medicine and of training about diagnosing pulmonary embolism (PE) on positive results of CTPA. "

01/01/2012 - "The management of chronic thromboembolic pulmonary hypertension (CTEPH) is dependent on the extent of pulmonary artery obstruction, which is usually evaluated by planar perfusion scanning and CT pulmonary angiography (CTPA). "
02/01/2014 - "The aim of the study was to determine whether automated quantification of pulmonary perfused blood volume (PBV) in dual-energy computed tomography pulmonary angiography (DE-CTPA) can be used to assess the severity of chronic thromboembolic pulmonary hypertension (CTEPH). "
01/01/2016 - "Assessment of operability by means of CTPA and perfusion SPECT in patients with chronic thromboembolic pulmonary hypertension."
04/01/2015 - "The most common feature of pulmonary hypertension (PH) on computed tomography pulmonary angiography (CTPA) is an increased diameter-ratio of the pulmonary artery to the ascending aorta (PA/AAAX). "
07/01/2014 - "The aim was to assess dynamic and static parameters on routine computed tomography pulmonary angiography (CTPA) that may detect pulmonary hypertension (PH). "

01/01/2006 - "The management of suspected venous thromboembolism (VTE) could be improved; it is likely that after hours CTPA could be reduced."
10/01/2006 - "A total of 483 patients with a negative CTPA study were followed up for 3 months, with the aim of detecting episodes of venous thromboembolism and mortality. "
12/07/2004 - "Data were extracted on participants, CTPA technique, diagnostic studies performed, prevalence of PE, number of patients with negative or indeterminate CTPA results who were followed, and subsequent rates of venous thromboembolism and fatal PE. "
09/01/2009 - "If patients who received prophylactic anticoagulation or inferior vena cava interruption (n = 25) were excluded, NPV decreases to 96.5% A negative CTPA/CTV is reliable for the exclusion of significant venous thromboembolism in ICU patients."
04/01/2006 - "To determine the diagnostic quality, performance characteristics and interreader reliability of computed tomography pulmonary angiography (CTPA) and venography (CTV) in intensive care unit (ICU) patients with suspected venous thromboembolism (VTE). "

01/01/2012 - "Compression ultrasonography of the proximal lower extremities, an imaging study without ionizing radiation, should be considered for patients suspected of acute PE with signs of lower extremity deep venous thrombosis or for patients with negative CTPA or V/Q scan with discordant clinical probability. "
09/01/2013 - "Computed tomography venography (CTV) of lower limb veins and CTPA can be performed simultaneously, allowing for visualization of lower limb deep vein thrombosis (DVT). "
03/01/2013 - "A short-cut review was carried out to establish whether CT pulmonary angiography (CTPA) or ventilation-perfusion (VQ) scanning offer advantages in imaging the pregnant woman with a possible deep vein thrombosis. "
01/01/2013 - "A lower extremity duplex ultrasound confirmed deep venous thrombosis in 17 (9.1%) of the patients with suspected PE, at least 1 week prior to having CTPA. "
04/01/2012 - "Compression ultrasonography and ventilation perfusion scintigraphy are reserved for patients with concomitant suspicion of deep vein thrombosis or contraindication for CTPA. "

02/01/2010 - "Previous studies have shown that findings of computed tomography pulmonary angiography (CTPA) relate to outcome in pulmonary embolus (PE). "
12/01/2008 - "The main objective of this study was to assess the quality of CT pulmonary angiography (CTPA) for suspected pulmonary embolus (PE) in the pregnant population. "
02/01/2015 - "In pregnant women without embolism on CTPA, potential alternative causes for patient symptoms are seen on CT in 12% of cases."
01/01/2014 - "Repeat CTPA revealed extension of the clot burden, now a saddle embolus occluding pulmonary outflow. "
01/01/2013 - "We retrospectively reviewed CTPA done at our center over an eleven year period (2000 - 2010) in patients with suspected pulmonary embolus (PE). "
