Radiological risk analysis of image-guided interventional procedures

Wireless Accelerometer for MRI-Guided Interventional Procedures

MRI-guidance is increasingly used for minimally-invasive procedures, such as biopsy, and requires real-time active tracking of surgical instruments. Although optical and MR-based fiducial tracking devices have been used, these systems rely on complex contact with the operator or line-of-sight access for effective operation. A more straight-forward and clinically robust method is required to all...

Image-guided prostate radiotherapy: analysis of inter- fractional setup errors

Introduction: The accuracy of the patient setup and tumor location are major factors that determine the efficacy of radiotherapy treatment planning. In the prostate radiotherapy, reproducibility of the prostate location for each treatment fraction is problematic owing to varying filling of the rectum and bladder. According to this, the aim of this study was to measure the inte...

Efficacy of therapeutic fluoroscopy-guided lumbar spine interventional procedures.

PURPOSE To evaluate the benefit of fluoroscopy-guided lumbar spine interventional procedures in treatment of low back pain. METHODS This prospective descriptive study was performed on 60 patients with back/radicular pain after showing no improvement with conservative treatment. RESULTS One hundred and two injection sessions were done (average 1.7 injection per patient). Caudal and lumbar tr...
