The mean preradiosurgical maximum ADC (ADC max) values of all VSs were significantly higher for those with tumor regression or stabilization at last follow-up compared with those with progression (2.391 vs 1.826 × 10 −3 mm 2/sec p = 0.010). Cystic VSs exhibited a greater volume reduction ratio at last follow-up (cystic vs solid: 67.6% ± 24.1% vs 31.8% ± 51.9% p < 0.001). Compared with solid VSs, cystic VSs were more likely to regress or stabilize in the initial postradiosurgical 6–12-month period and during extended follow-up. Tumors that showed regression within the initial 12 months following radiosurgery were more likely to have a larger volume reduction ratio at last follow-up than those that did not (volume reduction ratio 55% vs 23.6%, respectively p < 0.001).
T2 fit maps were generated and T2 relaxation times were measured pre- and post-bracing. The postradiosurgical outcome was not significantly correlated with pretreatment volumes or postradiosurgical enhancing patterns. Cartilage was manually segmented in five regions of interest (ROIs) in the medial femur using OsiriX: medial anterior femur (MAF), medial central femur (MCF), medial posterior femur (MPF), medial anterior tibia (MAT), medial posterior tibia (MPT).
At last follow-up, imaging studies indicated that 150 tumors (80.2%) showed decreased tumor volume, 20 (10.7%) had stabilized, and 17 (9.1%) continued to grow following radiosurgery.
#OSIRIX MD STANFORD INSTALL#
Install it in less than 5 minutes, and you have a fully working medical imaging workstation, ready to import images from a PACS or directly from a CD or USB stick.The median follow-up period was 60.8 months (range 24–128.9 months), and the median treated tumor volume was 3.54 cm 3 (0.1–16.2 cm 3).
