EVALUATION OF RADIATION DOSES USING CONE BEAM COMPUTED TOMOGRAPHY IN ENDOVASCULAR AORTIC REPAIR AND SCOLIOSIS PROCEDURES
(2021-04-06)
Purpose: The study includes the two areas, vascular surgery and orthopedics, and focuses on
endovascular aortic aneurysm repair (EVAR) and scoliosis procedures. EVAR
procedures contribute to a high radiation dose to ...
DEVELOPMENT, VALIDATION AND APPLICATION OF A METHOD FOR DETERMINATION OF METABOLITE CONCENTRATIONS WITH PRECLINICAL MAGNETIC RESONANCE SPECTROSCOPY
(2021-05-10)
Background: Information on the metabolic content in tissue has diagnostic and prognostic
value when examining for example cancer and diseases of the brain. MR
spectroscopy is a non-invasive method that allows quantification ...
APOPTOTIC EFFECTS IN RENAL CORTEX AFTER TREATMENT WITH 177LU-OCTREOTATE
(2021-05-10)
Purpose: The purpose of this project was to investigate gene regulation of a predetermined
panel of apoptotic genes in murine renal cortex after treatment with 177Lu-octreotate
after one day and seven days.
Theory: ...
COMPARISON OF MULTI-CRITERIA OPTIMIZATION IN TWO DIFFERENT TREATMENT PLANNING SYSTEMS
(2021-05-10)
Purpose:
The purpose with this study was to compare multi-criteria optimization
(MCO) for volumetric modulated arc therapy (VMAT) treatment plans in
two different treatment planning systems.
Theory: When performing ...
The value of cardiac MRI texture analysis in patients with clinically suspected myocarditis
(2021-05-10)
Purpose: The aim of this proof-of-concept study was to assess the diagnostic value
of texture analysis (TA) based on conventional balanced steady-state-free precession (bSSFP), late gadolinium enhancement (LGE) and ...
DEFORMABLE IMAGE REGISTRATION OF SPINE MAGNETIC RESONANCE IMAGES WITH ELASTIX FOR DETAILED CHARACTERIZATION OF DISC LOADING BEHAVIORS
(2021-05-10)
Purpose: This work aimed to develop an optimized strategy for registration of spine magnetic
resonance (MR) images acquired with and without spinal loading, as well as evaluate
the quality of the registration strategy ...
ATLAS DATABASES OF HUMAN BRAIN ANATOMY: QUALITATIVE AND QUANTITATIVE COMPARISON
(2021-01-11)
The purpose of this study was to quantitatively and qualitatively compare the two brain atlases databases, Hammersmith and 2012 MICCAI Multi-Atlas Labelling Challenge data, by developing a quantitative method.
Theory
Anatomical ...
ENVIRONMENTAL RADIOLOGICAL STUDIES OF KVARNTORPSHÖGEN Dose and Radiological Risk Assessments for Humans and Biota
(2021-04-06)
Background: The pile Kvarntorpshögen and the lakes Surpölen and Norrtorpssjön are the remains of
an industry which mined and processed oil shales to extract oil during World War II. The pile mainly
consists of shale ...
FETAL DOSE ESTIMATION IN ABDOMINAL AND PELVIC CT EXAMINATIONS
(2021-05-10)
Purpose: The purpose of this is study was to compare different methods for estimating the fetal
dose, how much the different methods differ from each other and on which dose
levels the fetal doses are estimated to. ...
Characterization of discrepancies between manual and automatic segmentation to improve anatomical brain atlases
(2021-05-10)
Purpose: To characterize discrepancies between expert manually segmented brain images from
Hammers Atlas Database and automatically generated segmentations of the same
images; to decide whether they can be attributed ...
