Izvirni znanstveni članek
Oznake: PET/CT;voxel size;contrast recovery coefficient;contrast-to-noise ratio;
Background. PET/CT imaging is widely used in oncology and provides both metabolic and anatomic information. Because of the relatively poor spatial resolution of PET, the detection of small lesions is limited. The low spatial resolution introduces the partial-volume effect (PVE) which negatively affe ...

Doktorska disertacija
Oznake: onkologija;prehrana;
UVOD: Poleg podaljšanja celokupnega preživetja je glavni cilj zdravljenja razsejanega raka prostate ohranitev ali izboljšanje z zdravjem povezane kakovosti življenj. Eden od dejavnikov, ki bi lahko vplival na posameznikovo doživljanje z zdravjem povezane kakovosti življenja, je prehransko stanje. Zn ...

Semaglutide delays 4-hour gastric emptying in women with PCOS and obesity
Mojca Jensterle Sever, Simona Ferjan, Luka Ležaič, Aljaž Sočan, Katja Goričar, Katja Zaletel, Andrej Janež, Andrej Janež
Izvirni znanstveni članek
Oznake: PCOS;debelost;semaglutid;obesity;semaglutide;
Context: Semaglutide could contribute to reduced energy intake and weight loss by delaying gastric emptying (GE). However, the evidence for notable effects of semaglutide is inconclusive and compromised by the use of indirect methodology. Objective: to evaluate the effect of once-weekly subcutaneous ...

In the setting of primary hyperparathyroidism (PHPT), [18F]fluorocholine PET/CT (FCH-PET) has excellent diagnostic performance, with experienced practitioners achieving 97.7% accuracy in localising hyperfunctioning parathyroid tissue (HPTT). Due to the relative triviality of the task for human reade ...
