Abbreviations
- Computed tomography (CT)
Definitions
- CT plays complementary role to MR in preprocedural planning
- Assessment of osseous etiologies of back/neck pain
- Plan treatment approach
- CT plays complementary role to MR in preprocedural planning
Best Practice Guidelines
- CT scanners have wide detector arrays that enable increased coverage of patient anatomy in single rotation
- When using CT guidance for pain management procedures, users should be cognizant of radiation dose
- Image quality requirements for procedures are different from those for diagnostic CT procedures
- Acquire images only of area necessary to perform the procedure
- Reduce image quality (increase noise) wherever possible by acquiring images only of quality required to safely and accurately access target
- Monitor radiation dose to both patient and operators
- Be familiar with dose-reduction measures, such as tube current modulation and iterative image reconstruction
- Number of different dose indices are used to quantify and describe radiation dose from CT examinations, including weighted CT dose index (CTDIw), dose-length product (DLP), volume CTDI (CTDIvol), size-specific dose estimate (SSDE), and effective dose (E)
- Radiation dose associated with CT-guided pain management procedures is often at lower end of patient radiation doses that are normally encountered in diagnostic radiology
