Purpose: The aim of this research was to look at liver lesions on dual step computed tomography scans in people who had liver masses. In asymptomatic patients with normal liver function, an early diagnosis is beneficial. That also means the tumors can be treated more effectively with medications and radiotherapy. Material and Method: On ultrasound, 150 patients were shown to have a liver disease. 120 people were shown to have liver lesions after undergoing a biphasic CT scan. Following the maintenance of the IV-line, injection was injected using a pressure injector, and acquisition began. The arterial process was recorded for 15-20 seconds, and the portal venous phase was recorded for 50-60 seconds. Out of 120 cases, 30 had hypo vascular lesions that did not improve in both phases of the CT scan. This finding showed full enhancement on both arterial and venous phases on 25% of hypo vascular lesions and 75% of hyper vascular lesions. Conclusion: Biphasic computed tomography is an excellent diagnostic technique for detecting liver lesions whose visibility is based on their vascularity.
