We describe and discuss the application of three-dimensional (3D) time-of-flight (TOF) magnetic resonance angiography (MRA) to visualize non-invasively the cerebral vasculature of the rat. MR angiograms of healthy spontaneously hypertensive rats were obtained without the use of contrast agents. Tota

Ten healthy volunteers were imaged with breath-hold, three-dimensional (3D) time-of-flight (TOF) magnetic resonance angiography (MRA) using single-variable-angle uniform signal excitation (VUSE), double-VUSE, and flat radiofrequency (RF) pulses with various doses of contrast agent. The ability of ea
## Abstract ## Purpose To evaluate the combined use of carbon dioxide (CO~2~) and a gadoliniumβbased bloodβpool agent for magnetic resonance angiography (MRA). ## Materials and Methods After an initial intravenous injection of the bloodβpool agent Gadomer (Schering AG, Germany), repeated transca
