New CT scanner aims to spot tiny, dangerous lung clots

NCT ID NCT07575503

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study compares a new type of CT scanner (photon-counting CT) with standard CT to see if it can better detect very small blood clots in the lungs, called subsegmental pulmonary embolism. About 696 adults with suspected acute pulmonary embolism will be scanned with both methods. The goal is to improve diagnosis and guide treatment for these hard-to-find clots.
