Introduction: Patients with essential tremor (ET) have 3.5 times greater risk of developing Parkinson's disease (PD) throughout their lives, also known as PD antecedent ET (ET-PD). Single photon emission computed tomography radiotracer imaging dopamine transporters (TRODAT-SPECT) can help differentiate these two diseases. Method: Relate the results TRODAT-SPECT in patients to potential progress...

Background: Hairline rib fracture commonly happens after blunt trauma, and it is hard to be detected by X-ray. Many methods can used, among them, the hybrid image of single-photon emission computed tomography (SPECT) (CT) seems produce higher sensitivity for diagnosis. Case presentation: A 63-year-old man came our rehabilitation clinic a vehicle accident 25 days earlier. He had multiple plain f...

We review the developments made during the last decade in the theory of polarization bremsstrahlung in the non-relativistic domain. A literature survey covering the latest history of the phenomenon is given. The main features which distinguish the polarization bremsstrahlung from other mechanisms of radiation are discussed and illustrated by the results of numerical calculations.

We briefly discuss GLAST’s capabilities for observing high-energy radiation from various energetic phenomena in our solar system. These emissions include: bremsstrahlung, nuclear-line and pion-decay gamma-radiation, and neutrons from solar flares; bremsstrahlung and pion-decay gamma radiation from cosmic-ray interactions with the Sun, the Moon, and the Earth’s atmosphere; and inverse Compton ra...

Although both electron-ion and electron-electron bremsstrahlung contribute to the hard Xray emission from solar flares, the latter is normally ignored. Such an omission is not justified at electron (and photon) energies above ∼ 300 keV, and inclusion of the additional electron-electron bremsstrahlung in general makes the electron spectrum required to produce a given hard X-ray spectrum steeper ...

Cilj: Cilj rada bio je procijeniti doprinos jednofotonske emisijske tomografije / kompjutorizirane somatostatinskih receptora (SR SPECT/CT) s 99mTc-EDDA/HYNIC-Tyr3-oktreotidom (99mTc-Tektrotyd) u dijagnostici i procjeni proširenosti bolesti kod pacijenata oboljelih od neuroendokrinih tumora (NET-ova). Ispitanici metode: Retrospektivno analizirano 120 SR SPECT/CT snimanja patohistološki dokazani...

This paper describes a method and a control system of a scanning electron and a bremsstrahlung pulsed beam for industrial linac. The system uses ultrasonic emission generated by the beam in thin rods and plates, as a source of primary information about the current characteristics of each electron/bremsstrahlung pulse. The results of the uniform radiation field forming are discussed.

Post stroke dementia is one of the most common complications of stroke that is preventable and relatively treatable too. The purpose of the study is comparison between the positive findings in brain CT scan and brain perfusion SPECT. 15 patients who were complicated by dementia after cerebrovascular accident and also 5 patients as a control group enrolled in this study. Brain CT scan and ...
