**7.3 CT**

Relatively expensive method, greater exposure to ionizing radiation and in many places requires differentiated logistics, as the device is generally not limited only to biopsy procedures. Very useful in performing biopsies of complex structures, such as the pelvis or regions that require greater precision, from the surgeon, such as the spine. The accuracy of the CT-guided core-needle biopsy procedure is high, around 96%, and with a low complication rate, between 0 and 7.4% [56–59] (**Figure 9**).
