Yksityiskohtainen kuvaus
The AIG-SLD Screening Project is a single-arm, open-label, prospective interventional study designed to evaluate the effectiveness of a MAOSS-guided identification and AI-human collaboration recall strategy for detecting individuals at intermediate or high risk of steatotic liver disease (SLD) and for assessing intervention outcomes. The trail will prospectively and consecutively enroll around 8000 eligible adults aged ≥18 years who undergo routine chest or abdominal non-contrast CT (NCCT) with adequate hepatic coverage .
The AI system i.e. MAOSS will be embedded within the standard clinical workflow to evaluate the real-world performance and the impact of AIG-SLD screening. All eligible NCCT scans will be evaluated through two parallel streams:
- Standard of Care (SoC) workflow: Radiologists perform independent assessments, first-line radiologists review followed by a senior radiologist finalizing the report.
- AIG workflow: The MAOSS system simultaneously analyzes the identical imaging data in real-time.
The system screens patients with clinically suspected SLD by flagging those with a MAOSS score ≥1.6 and a FIBRO Score ≥1.7 for recall. These algorithmic flags will be compared against radiologists' determinations of clinically significant SLD. Management pathways are defined as follows: (1) Concordant cases: If the Standard of Care (SoC) and the AIG pathway agree (both recommending recall or both recommending no recall), the agreed-upon decision will be executed. (2) Discordant cases: If the SoC and AIG pathways disagree, patients will be recalled for primary hepatology care to ensure safety.
Primary hepatology care begins with the collection of questionnaires regarding medical history, lifestyle, alcohol consumption, and metabolic risks (Type 2 Diabetes Mellitus, obesity, metabolic syndrome, significant alcohol consumption, or viral hepatitis) followed by further serum laboratory tests and Transient Elastography (e.g., FibroScan). Recalled patients will be managed according to the MAOSS pathway starting with FIB-4 stratification (<1.3, 1.3-2.67, >2.67), followed by FAST stratification (<0.35, ≥0.35) as needed. Intermediate-to-high-risk patients will proceed to escalated care involving MRE, MRI-PDFF, or liver biopsy. Management is then determined by MRE-derived Liver Stiffness Measurement (LSM): patients with LSM < 3.5 kPa will receive lifestyle interventions and annual reassessment; those with LSM 3.5-5.0 kPa (F2-F3) will receive pharmacological or therapeutic interventions; and those with LSM ≥ 5.0 kPa (F4) will undergo cirrhosis-based management. Patients in the latter two groups will be reassessed every six months to monitor changes in steatosis and fibrosis.

Inclusion Criteria:
- Adults aged ≥18 years undergoing routine non-contrast or contrast-enhanced chest or abdominal CT examination.
- CT images with adequate hepatic coverage and sufficient image quality for MAOSS analysis.
- Willing to undergo the recall evaluation and either: having a FIB-4 result within the past 1 month, or willing to complete blood testing (ALT, AST, platelet count) required for FIB-4 calculation and undergo FibroScan or MRE assessment.
- Willing to participate in the study and able to provide written informed consent at the time of recall.
Exclusion Criteria:
- Known malignant liver tumors (e.g., HCC, cholangiocarcinoma) or a history of liver transplantation or major hepatic resection.
- Known cirrhosis based on noninvasive fibrosis assessment tests, liver biopsy or complications of decompensated disease, or with a documented history of cirrhosis identified by clinical notes will be excluded.
- Biliary obstruction, acute cholangitis, or other conditions that may interfere with interpretation of liver biochemistry or fibrosis risk assessment.
- CT images with severe artifacts or incomplete liver coverage preventing reliable MAOSS analysis.
- Severe acute systemic illness (e.g., sepsis, shock, acute heart failure), or pregnancy or breastfeeding.
- Unwilling or unable to complete recall procedures, including required blood tests, FibroScan, or MRE when indicated, or unable to comply with study follow-up.
- Severe comorbidity with an expected survival of less than 1 year (e.g., terminal malignancy).

Kokeellinen: AI-human collaboration for SLD screening
In the prospective analysis phase, all eligible NCCT scans will be evaluated through two parallel streams: 1.
Standard of Care (SoC) workflow: Radiologists perform independent assessments as per standard clinical procedures (e.g., first-line radiologists' reviews followed by senior radiologist finalizing the report).
2. AIG workflow: The MAOSS system simultaneously analyzes the identical imaging data in real-time.
|
The system screens patients with clinically suspected SLD by flagging those with a MAOSS score ≥1.6 and a FIBRO Score ≥1.7 for recall.
These algorithmic flags will be compared against radiologists' determinations of clinically significant SLD.
Management pathways are defined as follows: (1) Concordant cases: If the Standard of Care (SoC) and the AIG pathway agree (both recommending recall or both recommending no recall), the agreed-upon decision will be executed.
(2) Discordant cases: If the SoC and AIG pathways disagree, patients will be recalled for primary hepatology care to ensure safety and avoid potential missed diagnosis.

Effective referral yield for escalated hepatology care
Aikaikkuna: 6 months
|
Effective referral yield: the proportion of patients referred for escalated hepatology care confirmed with clinically significant (or above) fibrosis by MRE/liver biposy.
A non-inferiority test (and estimates of the associated absolute and relative differences) will be performed for effective referral yield between SoC and AIG workflow.
