Computed tomography

Computed tomography (CT) – is a diagnostic procedure utilizing X-rays to generate tomographic images or «slices» of a human body.  CT images of internal organs, bones, soft tissues, and blood vessels generate more information, compared to conventional X-ray images, providing three-dimensional representation of these structures. 

In patients with breast cancer CT is used to assess the extent of disease, particularly – to look for metastases (both regional and distant), and for assessment of systemic therapy efficacy.

In certain cases, CT may be prescribed when local recurrence is suspected, and to monitor the patients, who had completed their radical treatment. CT may be used as a navigation tool to perform the biopsy of the lesions, that cannot be assessed visually or by means of other navigation tools.  

CT is most often performed with intravenous injection of iodine contrast in patients with breast cancer. These contrasts help to visualize potential tumors and metastases and assess the blood vessels to the full extent. CT procedures are associated with certain exposure to radiation, but the clinical information that it provides usually has a great influence on the choice of therapeutic strategy for the patient. 

One of the important preconditions to maximize the clinical value of a CT scan is to repeatedly perform the procedure with similar quantities and methods as well as to archive the data of the previous scans.
