Resumen

Este estudio desarrolló una corrección de volumen parcial (PVC) mejorada con función de dispersión espacialmente variante (svPSF) para imágenes de SPECT de 177Lu-PSMA. El nuevo método mejora significativamente la precisión de la cuantificación sin introducir artefactos de ringing de Gibbs ni amplificación de ruido.

Positron Emission Tomography

Positron emission tomography (PET) is a medical imaging technique involving radiopharmaceuticals — substances that emit short-lived radiation. Although the first PET scanner was introduced in 1961, it took 15 more years before radiopharmaceuticals were combined with the technique and revolutionized its potential.
One of the main requirements of a PET scan is a positron-emitting radioisotope, which is produced in a cyclotron and then attached to a substance used by the part of the body...
