Methods and Materials
20 patients (13 ♂ and 7 ♀;age 32-70 years) with non-alcoholic liver steatosis,
diagnosed by liver US and clinical laboratory tests, underwent MR examination and BMI and FT measurement,
before and three months after a standardized dietetic therapy.
MR examinations were peformed with a 1.5 T Superconducting magnet (Magnetom Symphony,
Siemens) with high performing gradients (30 mT / m)and 6 breath-hold axial sequences:
-4 GRE T1-weighted sequences with IN/OUT phase TE
- 2 TSE T2-weighted sequences with/without fat saturation
HFF (hepatic fat fraction) was measured and its percentage of variation was quantized.
We compared the variation of average HFF with variation of BMI and FT.
Average HFF variation has been compared with HFF variation in each MR sequence.
The measurements were performed both manually and using FLA,
presenting them via summary tables and/or via some color maps.
We compared results from manual and FLA evaluation.
