  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. Classification in Bone Scintigraphy Images Using Convolutional Neural Networks

    University essay from Lunds universitet/Matematik LTH

    Author : Johnny Dang; [2016]
    Keywords : machine learning; deep learning; neural networks; convolutional neural networks; artificial neural network; ANN; CNN; bone scintigraphy; bone scan; prostate cancer; bone metastasis; bone scan index; Technology and Engineering;

    Abstract : The main goal of this thesis is to design and implement a convolutional neural network (CNN) to classify whether hotspots in bone scintigraphy images represent cancer metastases, caused by prostate cancer, or some other physiological process. A side task was included, where another CNN was designed and trained to classify whether a bone scintigraphy image image is acquired from the front of the patient (anterior) or from the back (posterior).

  4. 3. Olinjärt ultraljud för undersökning av sprickor i skelettet hos häst, en pilotstudie

    University essay from SLU/Dept. of Clinical Sciences

    Author : Katarina Sandelin; [2015]
    Keywords : skelettskada; NAW; sidband; mikrosprickor; fraktur; micro cracks; fracture; fissure; side band;

    Abstract : Fissurer och odislocerade frakturer hos häst kan ibland vara svåra att upptäcka utan avancerad bilddiagnostik. Det är dock viktigt att diagnostisera dem i tid för att hindra att skadorna förvärras. READ MORE

  5. 4. Volumetric Quantification of Metastatic Burden from SPECT/CT Images

    University essay from Lunds universitet/Matematik LTH

    Author : Hanna Carlsson; [2012]
    Keywords : Technology and Engineering;

    Abstract : Bone scintigraphy images are used to investigate the presence of metastases in patients with prostate cancer. An analysis of these images indicates the proportion of cancer in the bones; the Bone Scan Index (BSI). This value is an important prognostic factor used to predict the future for the patients.

  6. 5. Navicular bone location in radiographs and solar scintigrams : The radiographic location of the equine navicular bone in the front legs, the effect of leg positioning, and a method to position a navicular bone region of interest in a solar scintigram

    University essay from SLU/Dept. of Biomedical Sciences and Veterinary Public Health

    Author : Charles Ley; [2006]
    Keywords : horse ; equine; solar projection; scintigraphy; radiology; navicular; distal sesamoid bone; foot; proximal interphalangeal joint; pastern;

    Abstract : The anatomical location of the navicular bone region in the solar projection scintigram has not been clearly established and it is often not possible to define the navicular bone in solar projection bone phase scintigrams. This is due to the relatively poor anatomical detail of scintigrams. READ MORE
