This study aimed to evaluate the dynamic computed tomographic (CT) appearance of focal @entity1161 to cirrhotic liver tissue around the @entity5 following stereotactic body radiation therapy (SBRT) for @entity157 ( @entity157 ). Seventy-seven @entity1 with 92 HCCs were observed for >6 months. Sixty-four and 13 @entity1 belonged to @entity1 -Pugh class A and B, respectively. The median SBRT dose was 48 Gy/4fr. Dynamic CT scans were performed in non-enhanced, arterial, portal, and venous phases. The median follow-up period was 18 months. Dynamic CT appearances were classified into 3 types: type 1, hyperdensity in all enhanced phases; type 2, @entity6152 in arterial and portal phases; type 3, isodensity in all enhanced phases. @entity1605 or 3 appearances significantly changed to type 1, particularly in @entity1 belonging to @entity1 -Pugh class A. After 3-6 months, @entity1 -Pugh class B was a significant factor in type 3 @entity1 . Thus, dynamic CT appearances were classified into 3 patterns and significantly changed over time into the enhancement group (type 1) in most @entity1 belonging to @entity1 -Pugh class A. @entity1 -Pugh class B was a significant factor in the non-enhancement group (type 3).
