  1. 1. Feasibility of quantitative 99mTc-DPD scintigraphy SPECT/CT for assessing the burden of ATTR cardiac amyloidosis

    University essay from Umeå universitet/Radiofysik

    Author : Sajad Kadhim Khalaf; [2023]
    Keywords : QSPECT; Amyloidosis; ATTR; LVMI; Recovery Coefficient; SUV; Calibration;

    Abstract : Background: Amyloid transthyretin (ATTR) cardiomyopathy is caused by the deposition of misfolded proteins, known as amyloid fibrils, in the myocardium. Quantitative Single Photon Emission Computed Tomography (QSPECT) utilizing 99mTc-DPD scintigraphy has the potential to assess ATTR-suspected cardiac amyloidosis (CA). READ MORE

  3. 2. Feasibility of single time point dosimetry during 177Lu-PSMA-617 treatments of prostate cancer

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Elias Nilsson; [2022]
    Keywords : Medicine and Health Sciences;

    Abstract : Introduction: Standard dosimetry methods for radionuclide therapies re- quire imaging at multiple time points post injection. An alternative method has been presented in the literature that uses previously acquired pharma- cokinetic data to create so-called dose factors. READ MORE

  4. 3. Feasibility of Dynamic SPECT-Renography with Automated Evaluation Using a Deep Neural Network

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Viktor Rogowski; [2021]
    Keywords : Medicine and Health Sciences;

    Abstract : Introduction: Renography is a standard diagnostic examination that evaluates renal function, renal pelvic dilatation and urinary obstruction. Renography is performed by injecting a radiopharmaceutical (predominately 99mTc-MAG3) and using gamma camera to image the biodistribution in a dynamic sequence. READ MORE

  5. 4. Evaluation of internal dosimetry for 225- Ac using one single measurement based on 111-In imaging

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Selma Curkic; [2021]
    Keywords : Medicine and Health Sciences;

    Abstract : Background and aim: There is a high interest in determining the absorbed dose in tumors and organs for various radiotherapy cancer treatments. Due to limitations in today's methods of determining the patient specific absorbed dose it is usually not proceeded clinically. READ MORE

  6. 5. Volume calculation of the thyroid gland from SPECT images based on Monte Carlo simulations

    University essay from Umeå universitet/Radiofysik; Umeå universitet/Institutionen för fysik

    Author : Niklas Palmqvist; [2018]
    Keywords : nuclear medicine xeleris thyroid hyperthyroidism thyrotoxicosis monte carlo technetium iodine;

    Abstract : In this study the volume determination which is a part of the doseplanning for patients with thyrotoxicosis was investigated. The aim was to find an accurate method to determine the active volume with single photon emission tomography (SPECT) which in several studies have shown better results than with the currently used method planar scintigraphy (PS).
