Combined CT pulmonary angiography and CT venography permits comprehensive assessment for pulmonary embolism and deep venous thrombosis, and serves as a road map for therapy, although the reported yield of CT venography has decreased substantially in recent years as CTPA has been increasingly utilized/over-utilized, and CTV is not routinely performed in conjunction with CTPA at most institutions/practices, although there is still evidence to support its use, especially in high-risk patients.
This may be due to the prospective design of the present study, the exclusion of cases which were not thought to have a pulmonary embolus, and pulmonary angiography not being performed in any case.
Table 2 Sensitivity, specificity, likelihood ratios and predictive values of significant coagulopathy * in excluding acute pulmonary embolism or predicting pneumonia in patients with symptoms of acute pulmonary embolism requiring computed tomography pulmonary angiography compared to a positive d/dimers result (>0.
When chest radiographs are unremarkable and the clinical suspicion is present, further imaging with a contrast-enhanced multidetector CT scan or pulmonary angiography is recommended.

Conventional pulmonary angiography confirmed an LPA arising from the aortic arch, with no LPA stenosis and presumed to be at systemic aortic pressure, supplying the left lung.
4) Patients with pre-existing lung disease, radiographic abnormalities, and a history of lung resection (5) or pulmonary angiography are at higher risk.
Herold noted that most algorithms involve CT angiography, D-dimer testing, and ultrasound; lung ventilation-perfusion scanning and pulmonary angiography are rarely used.
We're also capturing excellent images for CT urography with isometric reconstruction and gated thoracic imaging for aortic dissections, which we have also expanded to include cardiac pulmonary angiography research.
