In this study a total of 26 male patients with diagnosed prostate cancer whom had undergone planar bone scintigraphy followed by a SPECT-screening. För att cancern ska kunna behandlas effektivt, måste man veta exakt var cancern finns. Därför utnyttjar Docrates Cancersjukhus allt oftare PET-DT-undersökningar för att planera behandlingen av patienter.

Single photon emission computed tomography ( SPECT) is a three-dimensional nuclear medicine imaging technique combining the information gained from scintigraphy with that of computed tomography. This allows the distribution of the radionuclide to be displayed in a three-dimensional manner offering CT är en roterande röntgenkamera som enbart, men detaljerat, avbildar kroppen i ”bildskivor”. Dessa bildskivor av kroppen kan fås i vilka riktningar som helst.

The main advantage of SPECT/CT is the increased specificity achieved through a more precise localization and characterization of functional findings. The improved diagnostic accuracy is also associated with greater diagnostic
SPECT scanning uses direct photon-emitting isotopes rather than radioisotopes. SPECT isotopes have an average half-life of 6-12 hours. SPECT instrumentation is highly variable; therefore, use of a
They also found that SPECT could distinguish depression from CDs with 86 percent accuracy. In addition, brain SPECT imaging showed the ability to distinguish depression or dementia in people with both with 83 percent accuracy.

This course provides delegates with the necessary underpinning knowledge to understand the principles of CT, in order to improve confidence in undertaking CT examinations with patients, solve problems at the scanner and to optimise protocols for PET-CT and SPECT-CT specific practices to give improved image quality and/or reduced radiation doses.

Depending on the system design, low- to high-quality CT scanners are used. Purpose Single-photon emission computed tomography (SPECT) combined with computed tomography (CT) was introduced as a hybrid SPECT/CT imaging modality two decades ago. The main advantage of SPECT/CT is the increased specificity achieved through a more precise localization and characterization of functional findings.
