What type of radiologic services includes both diagnostic and therapeutic applications?

The correct answer encompasses a broad scope of radiologic services that includes both diagnostic and therapeutic applications. Radiology as a whole refers to the medical discipline that uses imaging techniques, such as X-rays, MRIs, CT scans, and ultrasounds, primarily for diagnosis. However, it also includes interventions that are therapeutic in nature, such as certain radiologically guided procedures or the use of radiology in treatment pathways.

This option is the most comprehensive as it does not confine itself to just one aspect of radiologic services; rather, it integrates various fields within radiology that can serve both diagnostic and therapeutic purposes.

The other choices are more specific and do not cover the full range. For example, imaging guidance refers specifically to the use of imaging technologies to guide procedures rather than encompassing diagnostics on its own or specifying therapeutic components. Nuclear medicine primarily involves the use of radioactive substances both for imaging and for treating certain conditions, but its focus is more limited compared to the overall scope of radiology. Radiation oncology specifically deals with the treatment of cancer using radiation techniques, representing a distinct subfield that primarily focuses on therapy rather than the broad diagnostic capabilities found in general radiology.
