U.S., May 9 -- ClinicalTrials.gov registry received information related to the study (NCT07575503) titled 'Diagnostic Value of Photon-Counting CT in Subsegmental Pulmonary Embolism' on Nov. 17, 2025.
Brief Summary: Pulmonary embolism (PE) is a serious and potentially life-threatening condition caused by blood clots in the lungs. A particular type, subsegmental pulmonary embolism (SSPE), involves very small branches of the pulmonary arteries. Although these clots occur in smaller vessels, their risk of recurrence and complications may be similar to larger clots.
Conventional CT pulmonary angiography (CTPA) is the standard imaging test for suspected PE, but image quality can sometimes be limited by motion artifacts, poor contrast filling, o...
