DOI: 10.1088/1361-6560/ab4891
Abstract: OBJECTIVES Lowering either the administered activity or scan time is desirable in PET imaging as it decreases the patient's radiation burden or improves patient comfort and reduces motion artifacts. But reducing these parameters lowers overall… read more here.

DOI: 10.1134/s1054661819010073
Abstract: The objects recognition/identification problem is considered. More specifically, the identification of the objects according to their intensity form (shape) on images of a special class is in the focus of the paper. The considered special… read more here.

DOI: 10.1182/blood.2020006322
Abstract: CLL has one of the highest familial-risks among cancers. MBL, the precursor to CLL, has a higher prevalence (13-18%) in families with two or more members with CLL compared to the general population (5-12%). Although,… read more here.

3D Convolutional Neural Network-Based Denoising of Low-Count Whole-Body 18F-Fluorodeoxyglucose and 89Zr-Rituximab PET Scans

DOI: 10.3390/diagnostics12030596
Abstract: Acquisition time and injected activity of 18F-fluorodeoxyglucose (18F-FDG) PET should ideally be reduced. However, this decreases the signal-to-noise ratio (SNR), which impairs the diagnostic value of these PET scans. In addition, 89Zr-antibody PET is known… read more here.
