They underwent color and spectral Doppler sonographic examinations at the first visit and 1 month after beginning timolol. Hemangioma volume, arterial diameter (AD), venous diameter (VD), resistance index (RI), pulsatility index (PI), peak arterial systolic velocity (PASV), maximum venous velocity, and mean venous velocity were measured. Therapeutic outcome was assessed at 6 months.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The hemangiomas were classified as deep (55.4%), hybrid (28.9%), or superficial (15.7%) and were located in the head and neck (36.1%), limbs (21.7%), or torso (42.2%). Regression occurred in 53 patients (63.9%). Timolol was the most effective in patients aged 5\u20136 months, in superficial hemangiomas, and in hemangiomas located on the torso. Receiver operating characteristic analysis revealed that changes in RI (sensitivity\/specificity: 71.7%\/96.7%), PI (sensitivity\/specificity: 73.6%\/86.7%), PASV (sensitivity\/specificity: 81.1%\/80.0%), change in arterial diameter (sensitivity\/specificity: 58.5%\/83.3%), and change in venous diameter (sensitivity\/specificity: 62.3%\/73.3%) at 1 month could predict response to timolol
