Synthetic diagnosis of parotid tumor

Computed tomography (CT), ultrasounds, and radioisotope scintigraphy (RI scinti) were applied before operation to 156 patients with parotid tumor, and the result of each test and/or the synthetic study of them were compared with the findings during operation and the pathological diagnosis of isolated tissue. CT was found to be a very effective diagnostic aid in determining the location of the tumor. CT and ultrasounds both provided adequately reliable information regarding the tumor content. For diagnosing the malignancy of the tumor, synthetic diagnosis using CT, ultrasounds and RI scinti had a high diagnostic accuracy. By using the above mentioned methods of diagnosis, an accurate preoperative diagnosis of the tumor could be obtained.
