  2. 1. Aspects of PET-CT in prostate cancer. Protocol optimization, diagnostic accuracy, and dosimetry

    Author : Mimmi Bjöersdorff; Malmö Nuklearmedicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PET-CT; Prostatacancer; [18F]FCH; [18F]PSMA-1007; optimering; diagnostisk noggrannhet; dosimetri; PET-CT; Prostate Cancer; [18F]FCH; [18F]PSMA-1007; Optimization; Diagnostic accuracy; Dosimetric;

    Abstract : The PET-CT imaging modality is based on positron emission tomography combined with computed tomography. Before a PET-CT examination, a radioactive tracer (also called a radiopharmaceutical) is intravenously injected into the patient. PET technology images the distribution of this tracer element by detecting the decay. READ MORE
