[The MRI and clinical features of acinic cell carcinoma of the parotid gland].

Lin Chung Er Bi Yan Hou Tou Jing Wai Ke Za Zhi 2014 Dec;28(24):1968-71

Objective: To analyze the MR imaging findins of acinic cell carcinoma(ACC) in parotid gland and develop the diagnosis of this disease.

Method: The MR imaging fearures of 11 patients with pathologically proved ACC were retrospectively analyzed. MR imagings were analyzed in relation to the follow:amount, location, size, shape, margin, pseudocapsule, MR signal intensity and enhanced pattern and the cervical lymphadenopathy. Read More

Nihon Jibiinkoka Gakkai Kaiho 1992 Aug;95(8):1247-60

Department of Otolaryngology, School of Medicine, Chiba University.

Pulse transmission technique has been used and developed in the Department of Otorhinolaryngology, Chiba University, in order to estimate attenuation of ultrasound within tumors of the parotid gland in vitro. A new apparatus to measure the attenuated ultrasound within the tissue was devised by using a pulse reflection method. After the measurement in vivo, the same examination was performed in a specimen of the removed tumor in vitro after surgery. Read More
