The intra-operative hologram contributed to better imagination of tumor locations, and for determining the parenchymal dissection line in the hepatectomy for the patients with more than twenty (20) multiple colo-rectal liver metastases (CRLMs). In another case, the hologram enabled a safe Gliisonean pedicle approach for hepato-cellular carcinoma (HCC) with a hilar anatomical anomaly. Surgeons could easily compare the real patient’s anatomy and that of the hologram just before the hepatic hilar procedure.\nConclusions\nThis initial experience suggested that an intra-operative hologram with MR techniques contributed to “last-minute simulation”, not for “navigation”. The intra-operative hologram might be a new next-generation operation-supportive tool in terms of spatial awareness, sharing, and simplicity.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Wolters Kluwer
