SPECT-CT provides the ability to merge or combine the images often allowing the nuclear medicine specialist to more accurately pinpoint the site of any abnormality on your nuclear medicine scan. This may be of particular importance in certain clinical situations, when the interpretation of an area of interest may change depending on its location. For example, in small areas like the spine or feet, it is sometimes hard to determine from the nuclear medicine imaging alone whether the abnormality lies in the bone or the adjacent joints – fusing a SPECT with CT provides added confidence in identifying where the abnormality is.
The doctor who arranged for you to have this examination has asked the Radiologist to consider giving an injection as part of the test. The Radiologist will explain whether an injection is necessary once he has scanned the area. The injection, if necessary, will be of local anaesthetic and/or steroid medication. The Radiologist will answer any questions you have about the injection at the time. If you have concerns before the test please contact the doctor who you saw in clinic who will be able to discuss the injection further with you.
