CASCAP
โครงการพัฒนาระบบสาธารณสุขเพื่อการตรวจคัดกรอง ตรวจวินิจฉัย และบริหารจัดการผู้ป่วยมะเร็งท่อน้ำดี ในภาคตะวันออกเฉียงเหนือ (Cholangiocarcinoma Screening and Care Program: CASCAP)
Embedded Files
- Fatty liver
- Liver cirrhosis
- Periductal fibrosis
Normal parenchymal echo
Normal parenchymal echo
Liver echo > renal cortex
Liver echo < renal capsule (ตับดำกว่า เนื้อนอกของไต)
Visible tubular structures are hepatic vein ( intersegmental ) and portal vein ( intrasegmental )
Hepatic vein runs toward IVC with thin wall
Portal vein runs in middle part of the liver with echoic wall and accompanying bile duct ( content in periportal space HA,BD,LYMPH… )
Bile duct runs paralell with portal vein
Fatty liver
Fatty liver
Mild = midly increased liver echogenicity (compared to the renal cortex)
Moderate = blurring of veins margins
Severe = significant posterior shadowing
Cirrhosis
Cirrhosis
causes
Regeneration
Inflammation and Necrosis
