Application of different molecular imaging techniques in predicting the progress of abdominal aortic aneurysm / 中国胸心血管外科临床杂志

ABSTRACT

@#Abdominal aortic aneurysm (AAA) is a common lethal aortic disease in clinical practice. At present, the imaging diagnostic methods used for AAA mainly include Doppler ultrasound, computed tomography and magnetic resonance imaging (MRI), but these methods can only observe the morphological changes of the aorta. These techniques used for the risk assessment of aneurysms, such as aneurysm rupture have some certain limitations. With the continuous development of molecular imaging technology and the further understanding of the pathogenesis of AAA, positron emission tomography (PET), molecular MRI and single photon emission computed tomography (SPECT) techniques can be used to observe the pathological changes of the AAA and assess the risk of rupture from cell and molecular level. In this paper, the latest application of PET, molecular MRI, SPECT in the risk assessment was discussed.
