Combined analysis of multislice computed tomography coronary angiography and stress-rest myocardial perfusion imaging in detecting patients with significant proximal coronary artery stenosis.

29 Sep 2009 OBJECTIVE: Multislice computed tomography (MSCT) coronary angiography (CAG) is limited in detecting significant coronary artery stenosis because of its low specificity and positive predictive value. Stress-rest myocardial perfusion imaging (MPI) can ... Read more...

X-ray synchrotron radiation pseudo-holotomography as a new imaging technique to investigate angio- and microvasculogenesis with no usage of contrast agents.

30 Aug 2009 Standard X-ray micro-computed tomography is a technique that allows a good visualization of the structure of mineralized tissues and biomaterials, but it fails to finely discern soft tissues. Here, we used X-ray synchrotron radiation ... Read more...

Real-time integration of intracardiac echocardiography and electroanatomic mapping in PVCs arising from the LV anterior papillary muscle.

30 Aug 2009 A 54-year-old woman with idiopathic premature ventricular contractions (PVCs) underwent electrophysiological testing. Three-dimensional (3D) geometries of the papillary muscles and chamber of the left ventricle (LV) were reconstructed using a ... Read more...
