  1. 6. Lesion Segmentation in 3D FDG-PET/CT Scans Using Deep Learning

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Adam Maen; [2022]
    Keywords : ;

    Abstract : Drug development is an expensive, long and complex process for pharmaceutical companies all around the world. One way to make it more reliable is to evaluate the drug at its early stages, so the decision can be made to go forward or move to another drug, which is also a time-consuming and costly task to be done by human experts.

  3. 7. Hypoxic Target Volume Determination in PET/CT Imaging : The Impact of Deformable Image Registration

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Viktor Rosenberg; [2022]
    Keywords : Positron emission tomography; image registration; hypoxic tumour volume; dose escalation; tumour control probability;

    Abstract : Using a tailored dose distribution for personalized radiotherapy with the help of positron emission tomography (PET) might give an edge for successful tumour elimination. One of the main determinants for tumour radioresistance in several solid tumours has been investigated as hypoxia, including head and neck cancer (HNC). READ MORE

  6. 10. Quantification of cerebral blood flow with 15O-water PET : A comparison study between PET/CT and PET/MR and two different blood sampling instruments

    University essay from Umeå universitet/Institutionen för fysik; Umeå universitet/Diagnostisk radiologi

    Author : Amanda Eriksson; [2021]
    Keywords : Cerebral Blood Flow; CBF; oxygen-15-labelled water; PET CT; PET MR; Quantification of CBF; Image Derived Input Function; IDIF; Blood Sampled Input Function; BSIF; Arterial Input Function; AIF; Tracer Kinetic Modelling; Single Tissue Compartmental Model; 1TCM;

    Abstract : Cerebral blood flow quantification is a vital diagnostic tool for disease monitoring and used for diagnosing a variation of pathological conditions. The human brain requires roughly about 20 % of the total cardiac output to sustain normal functioning, hence the perfusion of blood is an important factor to deliver oxygenated blood. READ MORE
