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.

Report template — MRI of chest

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 (gadolínio). Achados: - Vasos: estruturas vasculares do mediastino com calibres preservados. - Mediastino: não se observam linfonodomegalias. - Pulmões: sem alterações evidentes ao método. Ressalta-se a baixa sensibilidade da ressonância magnética para a detecção de pequenas alterações pulmonares. Caso exista indicação, um estudo por tomografia computadorizada poderá trazer informações adicionais. - Espaços pleurais: ausência de derrame pleural. Não há pneumotórax. - Partes moles e estruturas ósseas: sem particularidades ao método. - Transição toracoabdominal: sem alterações evidentes. Comparação: Exames anteriores não disponíveis para a análise. Conclusão: Exame sem achados significativos.
