Liver Fat Fraction Workflow
Liver parenchyma fat fraction with sequence QA
Measures liver fat fraction from qualified PDFF, Dixon water/fat, or in-phase/opposed-phase MRI series using a dedicated liver analysis service.
Liver Fat Fraction
Reports liver parenchyma fat fraction from the best qualified sequence.
Sequence QA
Identifies whether the result used PDFF/fat fraction, Dixon water/fat, or in-phase/opposed-phase fallback.
Fat Fraction Map Snapshot
Generates a liver fat fraction map snapshot masked to measured parenchyma.
Parenchyma QA
Excludes vessels and hepatic cysts when labels are present and reports negative/out-of-range map values.
분할 출력
영상 데이터
Accepts abdominal MRI as DICOM files, DICOM ZIP, DICOM folder, or NIfTI volume. Preferred series are IDEAL-IQ, mDIXON Quant, PDFF, fat fraction maps, or other multi-echo liver fat series. If unavailable, the workflow falls back to matched Dixon water/fat images, then matched in-phase/opposed-phase images including VIBE or LAVA acquisitions.
기본 대상자 정보
Pseudo subject name is recommended. Height, Mayo classification fields, kidney volume fields, and PKD longitudinal fields are not required.
검사 메타데이터
Series descriptions, protocol names, sequence names, and image type metadata are used for sequence recognition.
사용 방법
1. Upload an abdominal MRI study with liver fat fraction workflow type.
2. The workflow checks for PDFF or fat fraction maps first.
3. If no PDFF source is available, it looks for matched Dixon water/fat images.
4. If those are unavailable, it can use matched in-phase/opposed-phase images as a fallback estimate.
5. Review the generated report for selected series, confidence, negative-value QA, and the liver fat fraction map snapshot.
