Biopsy under CT control (BCTC) as a method was introduced in the 80s. Its further evolution was dependent on the following factors:

There were 42 cases (28 males and 14 females), subjected to BCTC. A total number of procedures was 49. BCTC of the lumbar, thoracic, cervical and sacral spine was performed in 26, 4, 6 and 6 cases respectively. It was made in a CT room and in compliance with an algorithm, developed by us. Local anesthesia and an original navigation system were used.

The obtained results were indicative of:

The diagnostic accuracy was as high as 96%. There were no complications.

CT control was characterized by several advantages:

  1. 3-D imaging
  2. Imaging in an axial plane
  3. Possibility of obtaining more profound diagnostic information in comparison with ultrasonic and X-ray examinations.

However, CT control had the following shortcomings:

  1. Absence of an on-line mode
  2. Presence of artifacts in case of high-density neoplasms
  3. Impossibility of reliable interpretation of a CT image during movement, which demanded breath holding in CT examination of thoracic and abdominal cavities
  4. A radiation load on a patient.

Conclusions.BCTC is a highly effective and safe diagnostic method, used in oncologic diseases (1). Its results allow to determine further tactics of treatment in the majority of cases (2).
