However, this information is commonly extracted from the CT metadata, which is often wrong. This study aimed at developing an automatic pipeline for classifying intravenous (IV) contrast phases and additionally for identifying contrast media in the gastrointestinal tract (GIT).Materials and Methods: ...
We propose in this study a novel method that uses a random sampling mechanism on top of deep CNNs for the phase recognition of abdominal CT scans of four different phases: non-contrast, arterial, venous, and others. The CNNs work as a slice-wise phase prediction, while the random ...

Flexible injection design can help you realizing the simplest 1 phase single syringe injection, or finishing the complicated 8 phases dual syringe injection. All are in your control. The elaborate assistant tray on which operator can place the fluid bottles or other things , and put the con...
phases and the incorporation of techniques that enable identification of calcifications and characterization of renal lesions. It is also important to determine whether the examination will include the collecting system. Furthermore, the kidneys may differ in size, position, and function. Renal vascular...
For 13 out of 16 lesions, the Krenning score was identical in all the CT phases. In the remaining three lesions, the Krenning score differed by no more than one (Table3). Comparison of max pixel values for the 16 lesions showed significantly lower values for LD than for FD;p <...
The tumor textures were mainly heterogeneous (53.8%, 7/13) for ischemia or necrosis within the tumor center, with solid components dominantly in all cases, as shown in Table 3. The quantitative CECT parameters including the CT values, enhancement degree of the four phases of CECT and the dyna...
image gives a phases value approximately twice those in the tQPI image. As a result, this case will give a ratio α ≥ 2. Using linear regression fitting, we obtain α = 2.61 ± 0.82 and the R2 coefficient of 0.69. This fitting slope only varies slightly ...

While acquisition was performed for clinical purposes, respectively, the delayed contrast-enhanced phases of both SECT and DECT examinations were not used for further data analyses in this study. Radiation dose was recorded in the automatically generated patient dose report in the form of CT dose ...
