Spect CT is the technique which involves use of images acquired from two different types of body scans separately or in merged form. When used together, these images provide more detailed information on the functions of the various body areas and ensure for problems to be identified more clearly. The technique also offers information on the functions of organs.
Advantages: The images provided through the detectors of the Spect CT device, which rotates at degrees of 180 and 360 around the patient, are used to perform three-dimensional examinations.
The technique is used in sentinel lymph node mapping and, in particular, screening for involved lymph nodes in cases of breast cancer, malign melanomas, head and neck tumors, early stage cervical cancer and bladder cancer, as well as detection of metastases in malign diseases and differentiation between metastases and degenerative changes in cases of musculoskeletal system disorders.
It is also beneficial in parathyroid diseases, especially when it comes to detection of parathyroid adenomas.
Cardiac perfusion imaging is another area in which the technique is used. Spect CT scans are generally completed in 30 to 40 minutes.
