  1. 1. Evaluation of whole-body bone scans performed using a gamma camera with Cadmium Zinc Telluride detector

    Master-uppsats,

    Författare :Victor Asp; [2022-01-13]
    Nyckelord :Medical physics; whole-body bone scans; gamma camera; Cadmium Zinc Telluride detector;

    Sammanfattning : The bone scan is a common nuclear medicine imaging procedure that is mainly used for evaluating several oncological patient groups. A radioactive tracer, 99mTc -labelled diphosphonate, is injected intravenously and accumulates in the skeleton. The distribution of the tracer in the body is measured with a gamma camera 3 hours post-injection. LÄS MER

  2. 2. STANDARDIZED ORGAN AT RISK VOLUME FOR EXTERNAL BEAM RADIATION THERAPY IN PROSTATE CANCER AND ITS RELATIONSHIP TO VOLUMES DEFINED BY CLINICAL PRACTICE

    Master-uppsats,

    Författare :Dang Thao; [2022-01-13]
    Nyckelord :Medical physics; Radiation therapy; Prostate cancer; Organs at risk;

    Sammanfattning : Background/Purpose:In radiation therapy (RT), the radiation dose calculated in tumours and normal tissue depends on how the volumes are defined. It is difficult to standardize how tumour volumes should be defined because their anatomical extension can differ greatly between individuals. LÄS MER

  3. 3. Establishment of a deep learning algorithm for dosimetry of radiopharmaceuticals

    Master-uppsats,

    Författare :Dennis Lipnicevic; [2022-01-13]
    Nyckelord :Medical physics; automated segmentation; dosimetry; kidney; nuclear medicine dosimetry; deep learning; convolutional neural network;

    Sammanfattning : Purpose: The aim of this study was to introduce a volumetric convolutional neural network for segmentation of the kidneys in SPECT images and to apply it in the dosimetry of radiopharmaceuticals of this organ, in order to decrease segmentation time and to standardize the segmentation of the kidneys. Method: Three networks were trained using two network architectures and a total of 216 retrospectively collected images from patients that underwent imaging procedures at Sahlgrenska University Hospital between 2009 and 2018.

  4. 4. Sjuksköterskors upplevelser av att vårda patienter med Covid-19 : En litteraturstudie

    Kandidat-uppsats, Malmö universitet/Institutionen för vårdvetenskap (VV)

    Författare :Jamil Al Zahed; Rebecca Lenz; [2022]
    Nyckelord :Covid-19; sjuksköterskors upplevelser; vårda patienter; pandemi; omvårdnad;

    Sammanfattning : Bakgrund: Covid-19 är en pandemi som har pågått sedan slutet av 2019. Viruset har spridit sig över hela världen. Brist på planering, resurser och ledarskap har varit ett enormt problem under pandemin. LÄS MER

  5. 5. Graviditet i samband med underfunktion i sköldkörteln

    M1-uppsats, Linnéuniversitetet/Institutionen för kemi och biomedicin (KOB)

    Författare :Hanoaf Al-Dires; [2022]
    Nyckelord :Hypotyreos; subklinisk hypotyreos; graviditetskomplitaktioner; TSH; tyreoideahormoner; levotyroxin; LT4; tyreoperoxidas-antikroppar; TPOAk;

    Sammanfattning : Backgrond: The thyroid is a hormone-producing endocrine gland which is located in the front of the throat. The thyroid gland tissue contains several microscopic and spherical cavities called follicles. Thyroid hormones thyroxine (T4) and triiodothyronine (T3) are produced from the follicle cells and regulated by a so-called three-hormone sequence. LÄS MER
