One possible method of measuring T1 in rapidly acquired magnetic resonance images using variants of the FLASH technique is by the manipulation of the magnetization precession angle. It is suggested here that this method is as prone to slice-shape artifacts as many other approaches.
## Abstract Magnetization transfer (MT) techniques have been shown to significantly reduce background softβtissue signal in timeβofβflight magnetic resonance angiography. To achieve sufficient suppression, radio frequency (RF) pulses with tip angles on the order of 1000 degrees are typically used,
Most recently, time-resolved 2D MRA after injection of a contrast agent bolus for various applications has been proposed. Similar to conventional digital subtraction angiography (DSA), 2D MR DSA offers the ability to observe the dilution of the bolus in the vascular system during the passage with a
