Tomography2017, 3(2), 89-95;https://doi.org/10.18383/j.tom.2017.00004

1 June 2017

With DSC-MRI, contrast agent leakage effects in brain tumors can either be leveraged for percent signal recovery (PSR) measurements or be adequately resolved for accurate relative cerebral blood volume (rCBV) measurements. Leakage effects can be dimi...

Tomography2017, 3(2), 101-104;https://doi.org/10.18383/j.tom.2017.00007

1 June 2017

Gastrointestinal stromal tumor (GIST) frequently metastasizes to the liver, and conventional staging computed tomography (CT) protocols use multiphasic contrast enhancement for detection of hepatic lesions. We evaluated the sensitivity of arterial ph...
