The radiographic abnormalities of interest were track microhemorrhage, pneumocephalus, hematomas, and edema, and the occurrence of these findings in compare the detection of these complications between T1\/T2 gradient-echo (GRE) and T1\/T2 fluid-attenuated inversion recovery (FLAIR) magnetic resonance (MR) sequences was compared. The presence, size, and association of susceptibility artifact with other radiographic abnormalities was also described. Lastly, the association of multiple microelectrode cannula passes with each radiographic finding was evaluated. <jats:italic>Ad-hoc<\/jats:italic> investigation evaluated hemisphere-specific associations. Multiple logistic regression with Bonferroni correction (corrected <jats:italic>p<\/jats:italic> = 0.006) was used for all analysis.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Out of 198 DBS patients reviewed, 115 (58%) patients showed entry microhemorrhage; 77 (39%) track microhemorrhage; 44 (22%) edema; 69 (35%) pneumocephalus; and 12 (6%) intracranial hematoma. T2 GRE was better for detecting microhemorrhage (OR = 14.82, <jats:italic>p<\/jats:italic> &amp;lt; 0.0001 for entry site and OR = 4.03, <jats:italic>p<\/jats:italic> &amp;lt; 0.0001 for track) and pneumocephalus (OR = 11.86, <jats:italic>p<\/jats:italic> &amp;lt; 0.0001), while T2 FLAIR was better at detecting edema (OR = 123.6, <jats:italic>p<\/jats:italic> &amp;lt; 0.0001). The relatively common findings of microhemorrhage and edema were best visualized by T2 GRE and T2 FLAIR sequences, respectively. More passes intraoperatively was associated with detection of ipsilateral track microhemorrhage (OR = 7.151, <jats:italic>p<\/jats:italic> &amp;lt; 0.0001 left; OR = 8.953, <jats:italic>p<\/jats:italic> &amp;lt; 0.0001 right).
