Abdominal MRI Protocol for Liver Assessment

All exams were performed using a 1.5T scanner (Magnetom Aera, Siemens Healthineers, Erlangen, Germany), equipped with an 18-channel body array coil. The study protocol consisted of the following sequences: 1) standard abdominal MRI sequences: coronal and axial T₂ half-Fourier single-shot turbo spin-echo (HASTE), liver iron and fat quantification with multiecho Dixon (LiverLab), T₁ volumetric interpolated breath-hold examination [VIBE] before and after administration of 10 ml of gadoxetate disodium (Eovist/Primovist, Bayer Healthcare Pharmaceuticals, New Jersey, USA) at 2ml/s, T2* mapping (time to echo: 2.3–14.2 msec), and diffusion-weighted imaging, 2) research sequences: T₁ρ, pre-contrast T₁ mapping, T₁-HBP, 4D flow imaging, dynamic contrast-enhanced MRI, and MRE [5 (link), 35 (link)]. The data relevant to T₁ρ, 4D flow imaging, dynamic contrast-enhanced MRI, and MRE are not included in the current study and have been or will be reported separately [37 (link), 38 (link)].

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
