Abstract:
This is descriptive study which was done during February to April 2017 and was carried out in Police University Hospital and Royal Scan International Hospital. Khartoum - Sudan.
The aim of the study; to study liver tumors using triphasic spiral Computed Tomography.
A total of “50” patients were selected randomly; male (24) and female (26) all those patients have age (35-86) years, have signs of liver disorders and referred by physician.
All patients were examined by CT scanners using Toshiba CT scanner 64 slice ,Neo Soft 16 slice. After using of normal Renal Function Test, (Creatinine).
Ct abdominal scan performed for all patients after injection of contrast media intravenously.
The study used the time of contrast media to reach the tumor, the time of leaving and the type of enhancement to differentiate between benign and malignant tumors.
The results shown that the common liver tumors were malignant (70%) appears as hyperdense area related to liver parenchyma at arterial phase due to it hypervascularity and reaching of contrast rapidly (rapid wash-in), and hypo-dense area at venous phase due to rapid wash-out, and most frequently seen at the age between 54-62 years old (32%) with metastases at different organs (Kidney-Pancreas-Gall Bladder and Urinary Bladder) and most common in females than males, and benign tumors (30%) appear as peripheral hyper-dense area related to liver parenchyma at arterial phase due to it hypovascularity and reach of contrast slowly, or non-vascular (enhancement), and hyper-dense area at venous phase due to low wash-out of contrast from tumor Study concludes that Tri-phasic spiral CT is the golden standard modality to study the liver tumors and give clearly image of normal liver parenchyma and any pathology that affect it.
