Abstract:
Objective To study CT and MRI appearance of transient hepatic attenuation difference (THAI)) .to reveal the cause of THAD),and to avoid false positive and misdiagnosis.Methods 10 cases appearing THAD in CT and 5 cases appearing THAI) in MRI were reviewed and all were processed with plain scan and dy- namic contrast with CT or MRI.Results 7 cases appeared transienl hypertransfusion of CT,4 cases appeared tran- sient hypertransfusion of MRI;3 cases appeared transient Hypoperfusion of CT,1 case appeared transient hypoperfu- sion of MRI.Conclusion The appearance of THAD in CT and MRI,was related to the quick-scan with CT and MRI only sufficient comprehension of the characteristics of blood supply in normal physiology and pathology of liver, combined with plain scan,could make correct decision possible in the final diagnosis when it occurred regional perfu- sion difference in liver.
