Autor: Daisuke Oura, Soichiro Takamiya, Riku Ihara, Yoshimasa Niiya, Hiroyuki Sugimori

Publikováno v: Diagnostics, Vol 13, Iss 13, p 2138 (2023)

Predicting outcomes after mechanical thrombectomy (MT) remains challenging for patients with acute ischemic stroke (AIS). This study aimed to explore the usefulness of machine learning (ML) methods using detailed apparent diffusion coefficient (ADC)

Construction of super-rapid brain MRA using oblique transverse acquisition phase contrast angiography with tilted optimized non-saturated excitation pulse

Autor: Hiroyuki Sugimori, Shinpei Sato, Riku Ihara, Daisuke Oura, Eiichirou Myo

Publikováno v: Magnetic resonance imaging. 85

[Background] Magnetic resonance angiography (MRA) is one of the most important sequences to estimate a cerebrovascular disease. We often encounter poor image quality due to slow arterial flow related to aging and motion artifact caused by disturbance

Effect of Reduced Tube Voltage on Diagnostic Accuracy of CT Colonography

Autor: Tomoaki Koide, Riku Ihara, Yoshihiro Futamata

Publikováno v: Nihon Hoshasen Gijutsu Gakkai zasshi. 73(7)

The normal tube voltage in computed tomography colonography (CTC) is 120 kV. Some reports indicate that the use of a low tube voltage (lower than 120 kV) technique plays a significant role in reduction of radiation dose. However, to determine whether

[A pilot study of contrast medium dose reduction using low tube voltage and iterative reconstruction: computed tomography angiography of the head]

Autor: Riku Ihara, Kouhei Itou, Takayoshi Terashita, Yoshihiro Fuse

Publikováno v: Nihon Hoshasen Gijutsu Gakkai zasshi. 71(3)

This study aimed to reduce contrast medium dose without reducing the diagnostic capability of computed tomography (CT) angiography of the head. We evaluated the advanced statistical iterative reconstruction (ASiR) settings to adjust to low tube volta
