Multiphase CT


VinDr-Multiphase: A Benchmark Dataset for Phase Recognition in Abdominal Contrast-Enhanced CT Scans

Dataset Description

This dataset was used to develop and validate our proposed method for phase recognition in abdominal contrast-enhanced CT scans using deep learning and random sampling.

Figure 1: Visual differences between the Non-Contrast (NC), Arterial (A), and Venous (V) phases in CT scans. The radiation enhancement in the different phases helps to detect different lesions in CT scans such as metastases, central tumor necrosis, and other pathologies. Radiologists usually look at arteries or veins and parenchyma to distinguish the phases.
