Self‐Reported Motor and Nonmotor Symptoms, Prodromal Parkinson's Disease Probability, and Incident Parkinson's Disease in US Farmers

Movement Disorders, EarlyView.
Abstract Background Few studies have assessed motor and nonmotor symptoms and the prodromal probability of Parkinson's disease (PD) among farming populations. Objective The aim was to assess self‐reported nonmotor and motor symptoms and the prodromal PD probability in relation to incident PD among US farmers.

Inversion of the attenuated V-line transform for SPECT with Compton cameras [PDF]

arXiv, 2016
The Compton camera is a promising alternative to the Anger camera for imaging gamma radiation, with the potential to significantly increase the sensitivity of SPECT. Two-dimensional Compton camera image reconstruction can be implemented by inversion of the V-line transform, which integrates the emission distribution over V-lines (unions of two half ...

Pathophysiological Role of Primary Motor Cortex in Essential Tremor

Movement Disorders, EarlyView.
Abstract Background Essential tremor (ET) is one of the most prevalent movement disorders. However, the complete understanding of ET pathophysiology remains elusive. Objective To explore the pathophysiological role of primary motor cortex (M1) in ET, specifically exploring its neurophysiological changes and their correlation with voluntary motor ...

Automatic bone marrow segmentation for precise [177Lu]Lu‐PSMA‐617 dosimetry

Medical Physics, EarlyView.
Abstract Background Bone marrow (BM) is the dominant dose‐limiting organ in [177Lu]Lu‐PSMA‐617 therapy for patients with metastasized castration resistant prostate cancer, where BM dosimetry is challenging due to segmentation. Purpose We aim to develop an automatic image‐based segmentation method on peri‐therapeutic sequential [177Lu]Lu‐PSMA‐617 images

A novel fast strategy to calculate equieffective doses under different dose rate conditions

Medical Physics, EarlyView.
Abstract Background Radiopharmaceutical therapy (RPT) has gained notable attention for its potential in treating difficult cancers, with [177Lu]Lu‐DOTATATE being a notable example. However, the radiobiology of RPT is less understood compared to external beam radiotherapy (EBRT), and dosimetry protocols are not standardized.

Dual-Domain Coarse-to-Fine Progressive Estimation Network for Simultaneous Denoising, Limited-View Reconstruction, and Attenuation Correction of Cardiac SPECT [PDF]

arXiv
Single-Photon Emission Computed Tomography (SPECT) is widely applied for the diagnosis of coronary artery diseases. Low-dose (LD) SPECT aims to minimize radiation exposure but leads to increased image noise. Limited-view (LV) SPECT, such as the latest GE MyoSPECT ES system, enables accelerated scanning and reduces hardware expenses but degrades ...

Accuracy of a whole‐body single‐photon emission computed tomography with a thallium‐bromide detector: Verification via Monte Carlo simulations

Medical Physics, EarlyView.
Abstract Background Single‐photon emission computed tomography (SPECT) devices equipped with cadmium–zinc–telluride (CZT) detectors achieve high contrast resolution because of their enhanced energy resolution. Recently, thallium bromide (TlBr) has gained attention as a detector material because of its high atomic number and density.
