The most common MRI sequences are T1-weighted and T2-weighted scans. T1-weighted images are produced ... When injected during the scan, Gad changes signal intensities by shortening T1. Thus, Gad is ...

Pelvic imaging using T1- and T2-weighted MRI has conventionally been ... 2 This study systematically and quantitatively describes mp-MRI signal evolution over a period of 6 months following ...

Bradley: A proton density-weighted image is halfway between a T1- and a T2-weighted image ... Bradley: Signal to noise is the currency of MRI. High signal to noise can be traded for faster ...

These include T1 and T2 image mapping ... the heart muscle do not produce changes in signal intensity, motion, or enhancement on normal MRI scans, they may affect myocardial nuclear magnetic ...

The same area on the T2-weighted scan is dark with a surrounding bright signal. This is the characteristic picture of an acute (approximately 3 days old) hemorrhage on MRI. In the acute stage, ...

The following MRI features were considered: tumor margins (sharp versus undefined); signal intensity on T1 and T2 images (homogeneous vs heterogeneous); pattern of enhancement (ring, nodular or ...

The cyst followed fluid signal on magnetic resonance imaging (hypointense to isointense relative to CSF on T1-weighted images, hyperintense on T2-weighted images, and suppressed on fluid-attenuated ...

Prostate zonal anatomy is best demonstrated with MRI. On T2-weighted sequences ... it is important that a T1-weighted sequence is also performed to demonstrate high signal blood products.
