ACR indeterminate liver lesion found on ultrasound contrast multiphase CT MRI appropriateness criteria
| If CT shows | Usual approach |
|---|---|
| Normal blood vessel or harmless fatty-liver-related change | No separate treatment |
| Old, healed granuloma | Often no treatment, sometimes follow-up only |
| Active infection/abscess | Antibiotics, and sometimes needle drainage |
| TB-related granuloma | Anti-TB treatment only after a doctor confirms TB with appropriate tests |
| A lesion still unclear on CT | MRI liver, blood tests, and rarely biopsy may be needed |

How can I understand my CECT report results?
ACR liver lesion initial characterization CT report multiphasic CT liver terminology arterial phase washout
| If CECT report says | Easy meaning | What usually happens |
|---|---|---|
| No focal liver lesion / normal enhancement | The ultrasound area was likely not a true lump, or was a normal vessel-related appearance | No treatment for that area |
| Focal fatty sparing / focal fatty infiltration | A harmless uneven-fat area in fatty liver | Treat fatty liver with weight control, activity, no alcohol |
| Calcified granuloma / healed granuloma | An old, inactive inflammatory scar | Usually no treatment |
| Granulomatous lesion, correlate clinically | It might be inflammation from a prior/active infection, but CT cannot fully prove the cause | Doctor may order blood tests, TB-related evaluation if symptoms/risk, or occasionally biopsy |
| Cyst | A fluid-filled sac | Usually harmless if simple |
| Hemangioma | A common benign cluster of blood vessels | Usually no treatment |
| Abscess / collection | Infection or pus in the liver | Urgent doctor review, antibiotics, sometimes drainage |
| Indeterminate lesion | CT cannot identify it with certainty | MRI liver with contrast may be needed |
| Suspicious lesion / arterial enhancement with washout | A pattern that needs prompt specialist evaluation, especially if cirrhosis/hepatitis is present | Hepatologist review, MRI, blood tests, sometimes biopsy |
