A total of 42 samples were obtained. Depending on lesion size and location, 14\u201318-gauge MR-compatible biopsy sets with a length of 100 or 200 mm (Somatex Medical, Teltow, Germany), 14\u201318-gauge MR-compatible semiautomatic biopsy guns with a length of 100 or 150 mm (Invivo, Schwerin, Germany), or 11-gauge MR-compatible bone marrow biopsy needles with a length of 100 mm (Somatex Medical, Teltow, Germany) were employed.<\/jats:p><\/jats:sec>Results:<\/jats:title>All lesions were visible with continuous interactive imaging. Our initial results indicate that bFFE is particularly suitable for fast-moving organs (pulmonary, paracardial); moving organs are targeted better with T1-weighted (T1W) TSE, T1W FFE (liver) or T2-weighted (T2W) TSE (complicated cysts, adrenal glands), and static organs are successfully approached with proton density (PD) (spine) or T1W TSE (peripheral bones, musculoskeletal system). No adverse events related to the use of MRI were obtained. No complications occurred according to the Society of Interventional Radiology (SIR) clinical practice guidelines.<\/jats:p><\/jats:sec>Conclusion:<\/jats:title>Applying tailored interactive dynamic imaging sequences for continuous navigation to liver, bone, muscle, vertebral disc, soft tissue, and other lesions can improve the feasibility, image quality, and interventional accuracy of freehand MR-guided biopsies and may hence reduce the risk of complications.<\/jats:p><\/jats:sec>","DOI":"10.1515\/bmt-2015-0163","type":"journal-article","created":{"date-parts":[[2017,1,11]],"date-time":"2017-01-11T10:00:53Z","timestamp":1484128853000},"page":"557-563","source":"Crossref","is-referenced-by-count":3,"title":["Tailored
