Fast and efficient liver imaging with Primovist®/Eovist®

July 27, 2018 by
This liver workflow makes better use of the time between the dynamic and liver-specific phases – by shifting the time consuming acquisition of high-res T2w images and DWI to after the contrast injection and – by shortening the delay between contrast dynamics and the acquisition of hepatobiliary phase images. The protocols allow to perform a complete Primovist liver exam in a 30-minute exam slot. [...]

Faster Abdominal MRI Examinations by Limiting Table Movement

July 6, 2013 by
The article shows how to reduce total examination time of a non-contrast liver MRI/MRCP by up to 20% with no observable change in image quality. It presents a scanning protocol which prohibits table movement, particularly time-consuming shim data, throughout the course of the examination. [...]

Spectral Adiabatic Inversion Recovery (SPAIR) MR imaging of the Abdomen

July 6, 2013 by
SPAIR (Spectral Adiabatic Inversion Recovery) is a powerful technique for fat suppression which offers advantages over conventional fat suppression techniques. The technique is insensitive to B1 inhomogenities and only fat spins are suppressed/inverted. [...]

Revisiting Liver Imaging with VIBE

July 5, 2013 by
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. [...]

Large FOV Imaging at 3T with a 32-Channel Body Array Coil

July 5, 2013 by
This article shows the benefits of a 32-channel body coil for large field-of-view imaging in the abdomen and pelvis, including MR Angiography. The evolution of parallel imaging techniques has been very rapid, with realization of their full potential requiring development and utilization of MR systems with up to 32 receiver channels. [...]

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

July 5, 2013 by
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 […] [...]
