Automated Identification of Optimal Portal Venous Phase ...

Objectives: To develop a deep learning-based algorithm to automatically identify optimal portal venous phase timing (PVP-timing) so that image analysis techniques can be accurately performed on post contrast studies. Methods: 681 CT-scans (training: 479 CT-scans; validation: 202 CT-scans) from a multicenter clinical trial in patients with liver metastases from colorectal cancer …

Study For 86 patients undergoing portovenous phase CT abdomen scanning using an aortic bolus trigger + 45 seconds tech-nique, we asked the radiographers to record the time from injection start to bolus trigger. We then asked an experienced radiologist to review the cases and score them as to whether

Automated Identification of Optimal Portal Venous Phase ...

2020-2-1 · Image acquisition was performed according to each centers’ standard CT protocol for single portal venous phase, portal venous acquisition. The reference gold standard for the classification of PVP-timing as either optimal or nonoptimal was based on experienced radiologists' consensus opinion.

2019-11-19 · scan’s PVP (portal venous phase) timing based on a three-point scoring system. Any scan with differing scores was reevaluated by both radiologists and a consensus score was reached. Using these values, a computer-aided scoring algorithm of the PVP timing (CASAPVP) was developed. Potentially misclassified PVP timings were detected by the

2021-11-17 · The portal venous phase, also known as the late portal phase or hepatic phase, is a contrast-enhanced CT or MRI series that has the following characteristics: liver parenchyma is at its peak enhancement with a density 110 HU (an increase of at least 50 HU from the unenhanced baseline) 1,2. portal vein and hepatic veins are completely enhanced.

2020-10-5 · Timing of each scan is very important especially the arterial and portal venous phase. It is important to give proper breathing instructions during the first and second and second and third scans. Ask the patient to breath normally after the arterial phase scan then ask to hold their breath when there is about 4 seconds left for the venous scan.
