LI-RADS — when to use Primovist (gadoxetate)?

Hepatobiliary agent with specific hepatobiliary phase (20 min post-injection) helps characterize HCC, FNH and metastasis. Advantages in LR-3 and LR-4 with borderline washout features.

When MRI in pancreatitis?

Recurrent pancreatitis without clear etiology (MRCP for microlithiasis, congenital anomalies), chronic pancreatitis for duct mapping and cystic lesion characterization.

Liver fat quantification — which technique?

PDFF (proton density fat fraction) with multi-echo sequences is the non-invasive reference. > 5% indicates steatosis; correlate with biopsy in clinical studies.

When to use

Hepatobiliary MRI is superior to CT for focal liver lesion characterization (especially in cirrhotic liver — LI-RADS), biliary tree assessment (MRCP), chronic pancreatitis, Crohn's disease (MR enterography) and deep endometriosis.

What to evaluate

Focal liver lesions: T1/T2 signal, diffusion, dynamic enhancement pattern, hepatobiliary phase (with Primovist).
Biliary tree: caliber, filling defects, congenital anomalies.
Pancreas: main duct, focal lesions, calcifications.
Quantification: liver fat (PDFF), liver iron (R2*) when applicable.
Bowel (MR enterography): thickening, enhancement, inflammatory signs, fistulae.

Técnica: Foram obtidas imagens multiplanares ponderadas em T1 e T2, sem com a administração intravenosa do meio de contraste paramagnético hepatoespecífico. Análise: - Transição toracoabdominal: bases pulmonares de aspecto preservado. - Fígado: de dimensões normais e contornos regulares, com sinal preservado. Sinais de deposição adiposa no parênquima hepático, sendo calculada porcentagem de gordura no fígado em % (normal até 5%). Não foram detectadas lesões focais. - Vias biliares: intra ou extra-hepáticas sem dilatações. Colédoco de calibre normal, sem cálculos de volume apreciável. - Vesícula biliar: normodistendida, com paredes finas e conteúdo de sinal homogêneo. - Pâncreas: de dimensões normais e sinal preservado. Não há dilatação do ducto principal. - Baço: normal. - Rins: de dimensões normais e espessura do parênquima preservada. Não há hidronefrose. - Adrenais: sem nódulos. - Alças intestinais: alças do intestino delgado e grosso inclusas sem particularidades ao método. - Peritônio e retroperitônio: não se observam linfonodomegalias nos cortes obtidos. Ausência de líquido livre no abdome superior. - Vasos: aorta abdominal com calibre normal. Veias cava inferior, porta e hepáticas pérvias. - Partes moles e estruturas ósseas: sem alterações significativas evidentes. Comparação: Exames anteriores não disponíveis para a análise. Conclusão: Exame sem achados significativos.
