CT scanners are used to locate _____________.

CT scanners are sophisticated imaging devices that utilize X-rays to produce detailed cross-sectional images of the body. This capability allows healthcare professionals to visualize various internal structures and conditions with high precision.

In the context of the question, CT scans are indeed employed to locate tumors, blood clots, and anatomical malformations. Scans can clearly reveal tumors by highlighting abnormal growths in tissues. They are particularly effective in identifying blood clots in areas such as the lungs or brain, providing crucial information for diagnoses and treatment decisions. Furthermore, CT technology is advantageous in assessing a range of anatomical malformations, as it provides excellent detail of complex structures that may not be easily evaluated through other imaging modalities.

Since CT scanners can be used for all these purposes, the answer that encompasses the entire range of their capability is appropriate. Thus, the correct choice reflects the broad application of CT imaging in medical diagnostics.
