CT Versus V/Q Scan for Pulmonary Embolus. An important trial appears in the Journal of the American Medical Association (JAMA) of a prospective randomized trial comparing CT pulmonary angiography

Axial CECT coronal reconstruction shows distribution and number of cavitary nodules. The CT scans of 18 patients with documented pulmonary septic emboli were reviewed. Axial CT image viewed on lung window settings shows occluded, contracted left lower lobe pulmonary artery (arrowhead). There is decrease in lung attenuation of left lower and right upper lobes, and more normally perfused lung contributes to mosaic pattern of lung attenuation (arrows). Incidental note is made of centrilobular emphysema. Radiographic and CT findings in 15 patients with clinically documented septic pulmonary emboli were compared retrospectively. In most cases, radiographic changes were nonspecific.

(a) CT scan shows a pulmonary embolus that affects the segmental artery of the (a) CT scan obtained with an edge-enhancing algorithm shows a lung algorithm artifact that mimics acute pulmonary embolism (arrows). This finding is seen when viewed with mediastinal or pulmonary embolism-specific windows and manifests as a bright ring around pulmonary arteries, particularly if associated with a flow artifact. CT pulmonary angiography ― also called CT pulmonary embolism study ― creates 3D images that can detect abnormalities such as pulmonary embolism within the arteries in your lungs. In some cases, contrast material is given intravenously during the CT scan to outline the pulmonary arteries. Ventilation-perfusion scan (V/Q scan) Purpose: Our purpose is to describe the CT findings in pulmonary fat embolism syndrome (FES). Method: Chest radiographs and CT scans of six patients with pulmonary FES were reviewed. Initial and follow-up CT findings were noted, and the extent of CT abnormalities was correlated with partial pressure of arterial oxygen (PaO2).

Systemic air embolism (air in the systemic arterial circulation) is considered a rare complication of CT-guided percutaneous lung biopsy. Though often self-limiting, it can lead to disastrous, even fatal complications when the air embolus reaches the brain or coronary arteries.

Ventilation and perfusion lung scans are not routinely performed prior to lung resection. Discussion. Systemic air emboli are an uncommon (0.02% to 0.4%) complication of CT-guided lung biopsies.1 – 4 Other common causes of air emboli include surgery (especially neurosurgical and otolaryngological procedures), trauma, catheterization and other intravascular interventions, and barotrauma from mechanical ventilation and diving. 5 Air emboli occur when a direct channel of 2018-03-29 2018-09-30 2018-10-08 CT Versus V/Q Scan for Pulmonary Embolus.

Lungeemboli er en sykdom hvor en propp (embolus) av fast materiale (blodpropp) løsrives fra sitt opprinnelsessted - som regel fra blodårer i leggene eller i bekkenet, og fraktes med blodstrømmen til lungene, hvor den blokkerer en av pulsårene i lungene.

(6) Acute pulmonary embolism in Septic embolism in patient with multiple pulmonary nodules and extrapulmonary focus of infection Axial CECT shows multiple peripheral thick-walled cavitary nodules from septic emboli. Axial CECT coronal reconstruction shows distribution and number of cavitary nodules. CT pulmonary angiography (CTPA) is a pulmonary angiogram obtained using computed tomography (CT) with radiocontrast rather than right heart catheterization.
