summary

Summary summary

Evaluation on T2WI: the first case, hyperintensity lesion + higher intensity scar
Evaluation of the enhanced arterial phase: the first case, peripheral nodular enhancement
Assessment of enhanced portal phase: the first case, concentric progressive enhancement
Assess the enhancement delay period: the first case, continuous enhancement and no enhancement of the central scar

Supplementary case and explanation

Hepatocellular carcinoma , the main characteristics: enhanced scan "fast in and out", central fissure necrosis, obvious limited diffusion, false capsule
.

Hepatocellular carcinoma .
The main characteristics of hepatocellular carcinoma are: enhanced scan "fast in and out", central fissure necrosis, obvious limited diffusion, and false capsule
.

FNH , the main features: T2WI or other slightly higher signal, higher signal scar in the center, obvious tumor enhancement in the arterial phase, or slightly higher signal in the delayed phase, and iso-signal in the hepatobiliary phase
.

Liver metastases (liver puncture: small cell carcinoma; left lower lung occupancy was also found) , the main characteristics: small round shape, clear border, limited diffusion, lack of blood supply, delayed central enhancement
.

Liver metastases (liver puncture: small cell carcinoma; another found left lower lung space) Liver metastases (liver puncture: small cell carcinoma; another left lower lung space occupied) , main features: small round shape, clear border, diffuse Limitation, lack of blood supply, and central enhancement in the delayed phase
