Image-guided marking techniques in interventional radiology: A review of current evidence - 08/12/21
Highlights |
• | Interventional radiology provides multiples localization techniques that can be used in the marking process of various pathologies. |
• | Localization techniques can be used for non-palpable breast or lung, tumors before surgery, before stereotactic-radiotherapy of lung tumors, before percutaneous thermal ablation of non-visible hepatic tumors and a variety of other indications. |
• | Localization techniques mostly include hook wire placement, marking with ethiodized oil (Lipiodol®), dyes or radioisotope, and micro-coils or fiducial marker placement. |
Abstract |
Precise marking of lesions using image-guided techniques is essential, as imprecise targeting of a tumor can result in either insufficient excision/treatment with an increased risk of recurrence, or excessive removal of healthy tissue. Most frequent indications include localization of nonpalpable lesions before surgical resection (i.e., hook-wire localization of pulmonary nodules before video-assisted thoracoscopy) and definite marking of liver metastasis before neoadjuvant therapy. Other indications include marking of hepatocellular carcinomas that are not visible on ultrasound and unenhanced computed tomography before thermal ablation, of bone lesions before surgical excision, and of different visceral tumors before stereotactic radiotherapy. This review presents the different existing indications, assesses their usefulness, gives systematic details on the technique and lastly analyzes the current literature with emphasis on results and complications.
