Generally, UAE barely results in complications, but that guided by CT gives contrary outcomes owing to low accuracy.20 Open MRI guidance, as a simple, frameless stereotactic technique
, can prevent possible shift induced by ordinary stereotactic techniques
as well as the deviations caused by tissue movement.
The application of stereotactic technique is rapidly growing.
Although the growth of applications for stereotactic techniques is optimistic, little attention has been paid in terms of the coordinate accuracy, which would probably impede its future developments.
Imaging of fine microcalcifications has sometimes been difficult under stereotactic technique
. However, stereotactic imaging and core biopsy remain the standards of choice for work-up of most microcalcifications.
Magnetic resonance imaging guided breast biopsy using a frameless stereotactic technique

This is particularly important for high-dose, highly focused stereotactic techniques
that demand extreme geometric and dosimetric accuracy in all phases of the treatment workflow; from imaging, treatment planning to patient set up, image guidance and treatment delivery.
Frame-based stereotaxis is still the gold standard worldwide--the patient is fitted with a stereotactic frame that is bolted to the head--but there are some units that perform frameless stereotactic techniques
[sup] With this technique, CT is performed by using stereotactic techniques
, while the stereotactic coordinates and the outlines of the targeted nucleus are obtained with nonstereotactic MRI, and then the two datasets are fused.
acoustic neuromas, arteriovenous malformations (AVMs) with accuracy of 0.1 mm using stereotactic techniques
