Quantifying Liver Fat Fraction via MRI

All patients underwent MRI IDEAL-IQ Sequence to measure LFC and were subjected to upper abdominal scanning by a 3.0 T MRI scanner (GE Discovery 750 Plus, GE Healthcare, USA). After preoperative fasting and water deprivation for 4–6 h, patients were placed in a supine position with phased array coils in the center of the liver. The scanning range included the top of the diaphragm to the lower margin of the liver. Parameters of IDEAL-IQ Sequence were TR 15.6 ms, TE 4.6 ms, slice thickness of 10 mm, number of echoes 6, pixel bandwidth of 111.11 kHz, field of vision 44 cm × 44 cm, matrix size 224 × 160, and flip angle of 8°. The scan was acquired during a single breath hold, lasting less than 30 s. Images were collected to obtain in-phase, anti-phase, and liver fat fractions. The region of interest (ROI) of each patient was located at the right lobe of the liver and selected in parts with more substantial composition, less intrahepatic bile duct, and blood vessels, as shown in Fig. 1. Three circular ROIs with an area of about 1200 mm were determined by two radiologists at our hospital in a cross-double-blind way, and the mean LFC of ROI was obtained.Fig. 1

MRI Evaluation of Diabetic Limb Ischemia in Rabbits

Check if the same lab product or an alternative is used in the 5 most similar protocols

On days 1, 5, 10, 15, 20, and 25 after successful modeling of diabetes with limb ischemia in rabbits, an MRI of the right femur of all rabbits was performed using a 3.0‐T imager (GE Discovery 750 Plus; GE Healthcare, Chicago, IL, USA) with an eight‐channel knee coil. Routine MRI included coronal fast spin‐echo T1‐weighted anatomic images and fast spin‐echo T2‐weighted anatomic sequences, and the MRI parameters were as follows: T1‐weighted imaging/T2‐weighted imaging; repetition time (TR), 300/2500 ms; echo time (TE), 13/120 ms; section thickness, 3 mm; field‐of‐view, 160 × 160 mm; matrix, 512 × 512.
DCE‐MR images of rabbit hind limbs were obtained using a three‐dimensional liver acquisition volume acceleration (LAVA) sequence and an array spatial sensitivity encoding technique (ASSET). An unenhanced LAVA sequence with variable flip angles was acquired at a temporal resolution of 8 s/acquisition. Imaging parameters for DCE‐MRI were as follows: TR, 3.5 ms; TE, 1.6 ms; section thickness, 3 mm; field‐of‐view, 200 × 160 mm; matrix, 192 × 192; flip angle, 9° and 12°. Subsequently, under the same parameters as above, the coronal dynamically enhanced LAVA sequence was implemented with a flip angle of 12°, and 420 sections were acquired continuously without intervals in the same layer, including a total of 35 phases. The imaging duration was 4 min 31 s.

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.
