First-pass myocardial perfusion cardiovascular magnetic resonance at 3 Tesla.
PURPOSE To test the feasibility of first-pass contrast-enhanced myocardial perfusion imaging at 3 Tesla and to evaluate the change in perfusion index between normal, remote and ischemic myocardium, we obtained perfusion index from healthy subjects and patients with coronary artery stenosis. MATERIALS AND METHODS First-pass contrast-enhanced perfusion imaging was performed on 12 patients and 3...
متن کاملMouse myocardial first-pass perfusion imaging
Figure 3: (left) First-pass perfusion images in a mouse with myocardial infarction. (right) Signal intensity-time curves extracted from three different ROIs. At time ‘A’, a lower rate of contrast agent uptake was seen in the infarcted myocardium, followed by a period of delayed-enhancement ‘B’. Figure 2: (top) Typical first-pass perfusion images in a healthy mouse. (bottom) Signal intensity-tim...
متن کاملMyocardial first-pass perfusion magnetic resonance imaging: a multicenter dose-ranging study.
BACKGROUND MRI can identify patients with obstructive coronary artery disease by imaging the left ventricular myocardium during a first-pass contrast bolus in the presence and absence of pharmacologically induced myocardial hyperemia. The purpose of this multicenter dose-ranging study was to determine the minimally efficacious dose of gadopentetate dimeglumine injection (Magnevist Injection; Be...
متن کاملSteady-state first-pass perfusion (SSFPP): A 3D TWIST in myocardial first-pass perfusion imaging
A new approach to myocardial first-pass perfusion imaging is presented; this technique, called SSFPP, is based on 3D SSFP sequence whereby magnetization is maintained in constant steady-state, while data acquisition is gated to diastole. This results in high SNR and CNR, and other characteristics that can potentially mitigate dark rim artifacts. The high-blood myocardial contrast of SSFP allows...
