Highlights ■ Higher absorbed doses are associated with positive tumor responses in patients with hepatocellular carcinoma treated with Y-90 radioembolization. ■ Personalized dosimetry may improve treatment outcomes in selected patients. ■ Dosimetric parameters such as D30, D50, and D70 also correlate positively with objective responses, emphasizing the importance of precise dose calculation in treatment planning. ABSTRACT Objective: To evaluate the relationship between the absorbed dose and radiological response in patients with hepatocellular carcinoma undergoing resin microsphere radioembolization to enhance treatment […]

Highlights Once complete hepatocellular carcinoma necrosis is achieved, the diameter of the hepatocellular carcinoma decreases significantly, regardless of its initial size. Hepatocellular carcinoma >3cm showed greater reduction and longer time to recurrence. Hepatocellular carcinoma ≤3cm exhibited a shorter time to relapse. Recurrence rates were similar, as long as complete response was achieved. ABSTRACT Objective: To describe the radiological characteristics of hepatocellular carcinoma (HCC) lesions that achieved a complete response following drug-eluting bead transarterial chemoembolization (DEB-TACE) preceding liver transplantation. Methods: This […]

OBJETIVO: Avaliar a eficácia da ultrassonografia com contraste de microbolhas no diagnóstico do carcinoma hepatocelular e comparar seus resultados com os de ressonância magnética e anatomia patológica. MÉTODOS: Foram avaliados 29 hepatopatas crônicos candidatos ao transplante pelo programa de transplante hepático do Hospital Israelita Albert Einstein. Esses pacientes foram submetidos a ressonância magnética, ultrassonografia com contraste de microbolhas e biópsia hepática excisional. RESULTADOS: Houve concordância ótima entre os resultados da ultrassonografia com contraste de microbolhas e aqueles da ressonância magnética. […]
