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 2016-11-17 · Transient interruption of contrast bolus results in suboptimal opacification of the pulmonary artery on initial contrast bolus, with subsequent diagnostic scan for pulmonary embolus after repeat injection using high pitch FLASH CTA.

Suboptimal opacification of the pulmonary arteries

The reasons for suboptimal opacification of the pulmonary artery included transient contrast interruption (n = 63), delayed start of scanning due to concurrent examinations of another body part (n = 6), contrast extravasation (n = 4), extremely large body size of the patient (n = 3), erroneous ROI placement in bolus tracking (n = 2), and technical error (n = 1). Transient interruption of contrast material was considered to be the cause when there was poor opacification of the pulmonary 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 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 pulmonary arteries, particularly if the scan is obtained at deep inspiration.

An attenuation of 200 Hounsfield units (HU) was used as a cutoff between adequate and suboptimal studies. Statistical analysis compared attenuation means and number of arteries with adequate versus suboptimal attenuation.

Suboptimal enhancement of CT pulmonary angiograms leads to non diagnostic studies and therefore unnecessary exposure to contrast and radiation. The Cycle. The standard: Previously published research suggests that a level of 210 Hounsfield Units (HU) is required in the vessel to identify chronic thrombus from enhancing vessel [1].
