Any nuclear medicine department equipped with a modern hybrid scanner can now perform combined V/Q SPECT with CT (using low-dose protocols) to further enhance diagnostic accuracy. In this paper we describe an application called peFinder for document-level classification of CT pulmonary angiography reports. CT pulmonary angiography (CTPA) is the most commonly performed test to detect acute pulmonary embolism. Additional screening for lower limb DVT can be performed as well. The computed tomography pulmonary angiogram (CTPA/CTPE) is a commonly performed diagnostic examination to exclude pulmonary emboli.Each radiology department will have a slightly different method for achieving the same outcome, i.e. Fine slice pulmonary artery phase helical CT images were obtained from the lung apices to the lung bases. OpenUrl CrossRef PubMed. In this article, we describe the technique of CT pulmonary angiography, diagnostic criteria for acute and chronic pulmonary embolism, and causes of misdiagnosis of pulmonary embolism. TECHNIQUE: Postcontrast CT chest pulmonary embolism protocol, 100 mL of Isovue-300 contrast is utilized. This one-center retrospective cross-sectional study includes from 5565 (model 1) to 5296 (model 2) patients that were evaluated for suspected PE in 2015, among which 1331 (23.9% (model 1) to 25.1% (model 2)) underwent CTPA. Radiology 1998; 208:209-215. J Biomed Inform. The consistent use of standard terminology when reporting cardiac CT findings is part of a structured and comprehensive coronary CTA report. Pulmonary embolism (PE) is a common condition with high mortality and morbidity. We aimed to assess the incidence of PE in patients with COVID-19 infection and to evaluate the relationship between the CT severity of the disease and the laboratory indicators. The computed tomography pulmonary angiogram (CTPA/CTPE) is a commonly performed diagnostic examination to exclude pulmonary emboli.Each radiology department will have a slightly different method for achieving the same outcome, i.e. Correspondent: Thomas Ashley, MD. Structured CT angiography reporting templates are hypothesized to reduce resident revision rates for these complex studies. This one-center retrospective cross-sectional study includes from 5565 (model 1) to 5296 (model 2) patients that were evaluated for suspected PE in 2015, among which 1331 (23.9% (model 1) to 25.1% (model 2)) underwent CTPA. Rajiah P, Ciancibello L, Novak R, Sposato J, Landeras L, Gilkeson R. Rajiah P, et al. Since then, several groups of investigators in the United States and Europe have reported high accuracy of the technique (compared with sonography) for the diagnosis or exclusion of deep venous thrombosis (DVT) in the inguinal regions and thighs. To reduce any potential bias, the radiologists were blinded to the original radiology report of the CT pulmonary angiography study, the results of other imaging studies, and clinical and laboratory data. No bony abnormality is identified. %�쏢 Identifying chronic thromboembolic pulmonary disease as a cause of PH has major clinical implications as these patients could be potentially offered a surgical cure.

The pleural spaces are clear. CT pulmonary angiography showed abnormal communications between the left superior pulmonary vein (in yellow arrow) and left superior pulmonary artery (in red arrow). Accordingly, we sought to develop and validate a ML algorithm that is capable of consuming free-form computed tomography pulmonary angiography (CTPA) reports and generating structured reports. As a secondary goal, we sought to explore the utility of this algorithm in identifying problems with statements from the original reports. According to Johns Hopkins Medicine , CT angiographies are … The consistent use of standard terminology when reporting cardiac CT findings is part of a structured and comprehensive coronary CTA report. The heart, great vessels, trachea and oesophagus have a normal appearance. There are two principal approaches for performing a CTPA of high diagnostic quality: Pulmonary embolism is the third most common acute cardiovascular disease, after myocardial infarction and stroke, and results in an estimated 200,000-300,000 hospitalizations and 37,000-44,000 deaths per year in the United States [].In 1980, Godwin et al. Computed tomography angiography (also called CT angiography or CTA) is a computed tomography technique used to visualize arterial and venous vessels throughout the body. Ultra-low dose contrast CT pulmonary angiography in oncology patients using a high-pitch helical dual-source technology. Compared with CT pulmonary angiography, SPECT has higher sensitivity, a lower radiation dose, fewer technically suboptimal studies, and no contrast-related complications. TECHNIQUE: Axial computed tomographic angiography images of the chest with intravenous contrast using pulmonary embolism protocol. A pulmonary angiography is typically performed to measure the pressure of the blood vessels carrying blood to your lungs and to evaluate for blockages or … Pulmonary embolism (PE) is one of the known sequels of COVID-19 infection. Sample Reports CT . 2011; 44 (5): 728 – 737. Coronary Angiography Report Thomas Ashley, MD Reports of coronary angiography frequently determine underwrit-ing decisions. A. Ribeiro, A. Juhlin-Dannfelt, L.-Å. However, some radiologists are concerned about resultant decreased workflow efficiency. Step by step tutorial on how to interpret a CT Pulmonary Angiogram (aka CTPA or PE Study). The pulmonary arteries have a normal appearance with no fillings defects to suggest a pulmonary embolus. The following are several key points: Other medical imaging fields (e.g., screening mammography, screening lung CT) have developed standardized reporting protocols. The results of these do not exclude the likelihood of a PE and so a CT Pulmonary Angiography (CTPA) has been arranged. The interpretation of CTPA results, and use of the results in clinical decision-making is based on a combination of features in the radiology report and the pre test probability of pulmonary embolism. 5. Link, Google Scholar CT Angiography (CTA) Computed tomography angiography (CTA) uses an injection of contrast material into your blood vessels and CT scanning to help diagnose and evaluate blood vessel disease or related conditions, such as aneurysms or blockages.
