We compared the radiation dose and diagnostic accuracy on 120- and 100-kVp coronary computed tomography angiography (CCTA) scans whose contrast-to-noise ratio (CNR) was the same.We studied 1311 coronary artery segments from 100 patients. For 120-kVp

Publikováno v: Japanese Journal of Radiological Technology. 68:851-856

Computed tomography automatic exposure control (CT-AEC) technique is calculated from a localizer radiograph. When we perform neck and chest CT examination, at first, we acquire localizer radiograph and neck images by placing the arm in a lowered posi

Development of an automated processing method to detect still timing of cardiac motion for coronary magnetic resonance angiography

Autor: Hiroya Asou, Katsuhiro Ichikawa, Naoyuki Imada, Tomoyasu Satou, Takanori Masuda

Publikováno v: Medical Imaging: Image Processing

Whole-heart coronary magnetic resonance angiography (WH-MRA) is useful noninvasive examination. Its signal acquisition is performed during very short still timing in each cardiac motion cycle, and therefore the adequate still timing selection is impo
