CT pulmonary angiography is sensitive and easy to get, but for clinically stable patients, alternative tests reduce exposure radiation, cost less, and are less likely to lead to overdiagnosis . Methods. CTPA was introduced in the 1990s as an alternative to ventilation/perfusion scanning, which relies on radionuclide imaging of the blood vessels of the lung. The test uses a special type of X-ray dye. The sensitivity of CT angiography in the diagnosis or exclusion of PE in all pulmonary arteries (to the level of the subsegmental pulmonary arteries) was 0.68 on the basis of a specificity of 0.91. CT coronary angiogram is non-invasive and is one of the most accurate tests to detect coronary heart disease and is able to eliminate the need for invasive coronary angiography.

(3) Can CTPA be used to evaluate right ventricular dilatation (RVD)? We conducted a study to answer 3 questions: (1) is CT pulmonary angiography (CTPA) overutilized in suspected pulmonary embolism (PE)? When used in conjunction with validated clinical decision tools like modified Wells criteria, CT-angiography is highly sensitive (good at detecting PE when it's there and ruling it out when it's not) and specific (generating few false-positive results). A CT angiogram positive for pulmonary embolism (PE) was extremely unlikely (0.95% chance) if patients had none of the studied thromboembolic risk factors. The mean d-dimer value was 5.5 mg/L FEU ± 8.2 (range, 0–55 mg/L FEU) in this group. A computerized tomography (CT) coronary angiogram is an imaging test that looks at the arteries that supply blood to your heart. The objective of this study was to describe the ED patient course and short-term safety for these evaluation methods. CT Pulmonary Angiogram at Lucid Medical Diagnostics, Banjara Hills.
