Revisiting Liver Imaging with VIBE

July 5, 2013 by Vamsi Narra, MD

Volume Interpolated Breath-hold Examination (VIBE) offers three-dimensional multiphase image acquisition before and following contrast administration on a breath-hold time scale. The dynamic behavior of liver lesions and structures during the precontrast, arterial, portal venous, early equilibrium and 5-minute delayed equilibrium phases of enhancement allows more accurate characterization than static pre- and postcontrast analysis. [...]

syngo BLADE Motion Correction from Head to Toe

July 5, 2013 by MRI

BLADE measures and corrects in-plane motion through periodically rotated overlapping parallel lines with enhanced reconstruction. syngo BLADE acquires multiple low resolution data sets and combines them to make one motion free, high quality image. This provides clear images in all slice orientations and body regions such as the head, spine, liver or knee. [...]

Case Report: Metastases from Neuroendocrine Carcinoma: Value of Diffusion-Weighted MR Imaging Compared to 68Ga-DOTATOC PET-CT

July 5, 2013 by Bernhard Klumpp, MD

Neuroendocrine tumors may be challenging to diagnose. Diffusion-weighted MR imaging (DWI) plays an important role in the accurate detection of liver lesions, which may be occult onconventional MRI and especially CT. In the presented case, the suspicion of diffuse hepatic spread is also supported by the additionally performed 68Ga-DOTATOC PET. The article shows, that DWI […] [...]
