Pulmonary emboli affect between 300,000-600,000 Americans every year and result in 12,000-80,000 deaths/year. Computed Tomography Pulmonary Angiogram (CTPA) is the reference standard for  imaging pulmonary emboli. However, radiologists miss visible emboli in 3-10% of cases. Delay of treatment or lack of treatment results in increased morbidity and mortality.

Team CT proposes to apply novel image analysis techniques and computer vision to design a computer aided detection system for pulmonary emboli in computed tomography pulmonary angiography, helping radiologists to make timely, accurate interpretation of CTPA images.

From the January 2013 newsletter:

The CAD-PE challenge

Team PET and their collaborators in Madrid and Boston are developing a method for computer aided detection of pulmonary embolisms. The current standard for screening misses as many as 10% of threats. They invite you to join the CAD-PE Challenge to help improve detection techniques that could save thousands of lives each year.

A pulmonary (thrombo)-embolism (PE) refers to the situation when a portion of a blood clot becomes lodged in a pulmonary artery. PE affects between 300,000-600,000 Americans every year and results in 12,000-80,000 deaths/ year.

Computed Tomography Pulmonary Angiogram (CTPA) is the reference standard in imaging of pulmonary emboli. However, radiologists miss visible emboli in 3-10% of cases [2,3,4]. Delay of treatment or lack of treatment results in increased morbidity and mortality [5]. Computer Aided Detection (CAD) systems to detect PE exist [6], but do not yield adequate specificity for their use in clinical practice [7] and increase read time [8]. This challenge is designed to foster research in the field of CAD for PE and to provide an objective benchmark with which to compare different algorithms of CAD for PE.
