ObjectiveTo summarize the guiding role of imaging evaluation of oblique lumbar interbody fusion (OLIF) in recent years.MethodsThe reports of OLIF surgical imaging research at home and abroad in recent years were extensively reviewed and analyzed.ResultsPreoperative imaging evaluation plays an important role in guiding the operation of OLIF, the placement of fusion Cage, the selection of indications, and the reduction of complications.ConclusionDetailed preoperative imaging evaluation can correctly estimate the indications of OLIF, and avoid the nerve, blood vessel, and muscle injuries.
ObjectiveTo summarize the common imaging features of liver cancer after local-regional therapy in order to more accurately evaluate the post-treatment response of it. MethodThe literatures of studies on imaging features after ablation, transcatheter therapy, and radiotherapy of liver cancer in recent years were searched and reviewed. ResultsIt was not accurate to evaluate the response of liver cancer after treatment only by comparing the size of tumor before and after treatment. We should follow up and observe the changes of enhancement components after tumor treatment, and pay attention to identify the normal features after treatment. ConclusionsImaging evaluation after local-regional therapy of liver cancer is of great significance in management and clinical decision-making of patients with liver cancer. Standard response evaluation systems such as EASL or mRECIST should be carefully applied after local-regional therapy of liver cancer. Treatment response of patients should be comprehensively evaluated in combination with the characteristics of local-regional therapy methods and timing, so as to avoid delaying timing of secondary treatment and causing excessive treatment.
