Detection of liver metastases from colorectal carcinoma: is there a place for routine computed tomography arteriography?
Although CCTA seems to be superior to other preoperative imaging techniques, the too low specificity will hamper its routine application in patients with hepatic metastases from colorectal carcinoma.
Unlike previous reports, this retrospective evaluation of B2A therapy in HF patients shows no relationship with long-term mortality when adjusted for population differences including BNP.  Large, prospective studies are required to define the risk/benefit ratio of B2As in patients with heart failure.
