ABSTRACT
Objective To study the manifestations of perfusion change in small heptic cell cancer(SHCC) on dynamic contract-enhanced MRI. Methods 18 cases of SHCC(21 lesions) proved by pathology were presented. Dynamic contrast-enhanced MRI was performed using 2D T_1-turbor-FLASH sequence for 18 SHCC.Results Among all 18 cases of SHCC, 17 cases were obvious enhanced, and one case was no enhancement. In 17caese of enhanced tumors, the maximal peak of enhancement was in the first set (6~23 s) in 2 cases and in the second set (33~51 s) in 15 cases. The average maximal peak of contrast-enhanced time was 42.5 s(23~50.5 s),and the average maximal peak of signal intensity increased up to 30.5 (19.5~45.0). The pattern of time-intensity curve was rapid wash-in followed by washout in 17 cases.Conclusion Dynamic contract-enhanced MRI is important on study and diagnosis of SHCC.
ABSTRACT
Few reports concerning the CT feature of electric shock-induced liver damages have ever been published. This paper presents such a case treated in our Institute.
