Elimination of deep inspiration reduced suboptimal opacification of the pulmonary artery (PA), from 7.3% to 2.7%, with 2.7% of the deep inspiration scans having attenuation values <150 Hounsfield CT is a sensitive tool for the evaluation of pulmonary arteries and for detection of PE.9 However, suboptimal studies account for up to 10.8% of all CT pulmonary angiograms performed.10 Suboptimal image quality can arise when motion artifact obscures the pulmonary arteries or nonopacification of the pulmonary arteries mimics or obscures a PE.11 Case example of positive CTPA with a dual-layer spectral CT: the low monoenergetic (monoE, 45 keV) recons are used to provide an iodine boost to the pulmonary arteries, good if there is suboptimal contrast opacification as in this case. the Z e 2020-06-02 ICD-10-CM Codes › I00-I99 Diseases of the circulatory system ; I70-I79 Diseases of arteries, arterioles and capillaries ; Other disorders of arteries and arterioles I77 Other disorders of arteries and arterioles I77- 2007-02-01 In chest CT examinations in which the pulmonary artery is suboptimally enhanced, obtaining virtual monoenergetic images at a low energy setting using dual-layer detector spectral CT allows sufficient attenuation of the pulmonary artery to be achieved while preserving image quality and increasing diagnostic performance for detecting PE. Pulmonary opacification. Pulmonary opacification represents the result of a decrease in the ratio of gas to soft tissue (blood, lung parenchyma and stroma) in the lung. When reviewing an area of increased attenuation (opacification) on a chest radiograph or CT it is vital to determine where the opacification is. Conventional 120-kVp image (top row,left image) shows suboptimal opacification of pulmonary artery (144 HU). There are suspicious emboli in both lower lobe segmental pulmonary arteries (arrows). However, differentiation between enhanced and nonenhanced portions of vessels.

Repeat injection with the left arm down by the patient’s side (b) shows excellent opacification of the left subclavian vein and no filling of venous collaterals, permitting a diagnostic scan for evaluation of pulmonary embolus Transient interruption of contrast material was the most common cause of suboptimal opacification of the pulmonary artery in this study. The instruction to take a deep inspiration at the beginning of the examination might have caused transient interruption of contrast material in some of our patients. Hounsfield Units (HU) of less than 200 measured in the main pulmonary artery (MPA) was considered suboptimal opacification. Potential contributing factors were grouped into four major categories, namely patient, radiologist, technologist, and equipment (Graph 1). Our technique was optimized based on current literature recommendations. The suboptimal opacification in pulmonary artery could be salvaged using low-energy virtual monoenergetic images (VMI) at rapid kVp switch dual energy CT.To explore the potential improvement in pulmonary artery opacification and to assess the change in image quality parameters in VMI using fast switch kVp dual energy CT.The CT images of 877 patients who were referred with a preliminary diagnosis of pulmonary embolism were reviewed.

Objectives: To explore the potential improvement in pulmonary artery opacification and to assess the change in image quality parameters in VMI using fast switch kVp dual energy CT. The most obvious anatomic causes for suboptimal opacification of the pulmonary arteries include obstruction of the superior vena cava, a substantial left-to-right shunt, or a patent foramen ovale – all of which will reduce opacification; up to a fifth of patients investigated have a patent foramen ovale and as a consequence there may be early opacification of the aorta, with suboptimal opacification of the … Suboptimal CT Pulmonary Angiography In The Investigation Of Pulmonary Embolic Disease: Incidence And Outcomes In A UK District General Hospital Abstract Send to Citation Mgr Opacification On Chest X Ray .

At each level the region of interest in each anatomical area was standardized as follows: 200−300 mm 2 for the central pulmonary trunk and the main pulmonary arteries (see Fig. 4). The pulmonary arteries are part of the pulmonary circulation, which also includes pulmonary veins and pulmonary capillaries. The purpose of the pulmonary circulation is to transfer oxygen and carbon dioxide between the blood in the body and the air that's inhaled and exhaled in the lungs. the contrast kinetics resulting in suboptimal opacifi-cation of the vessels. In our case, despite the bolus- tracking method, there was inadequate scanning time delay resulting in suboptimal enhancement of the pulmonary arteries.
