Objective To compare the value of transrectal ultrasonography(TRUS) and magnetic resonance(MR) in preoperative estimation of circumferential resection margin (CRM) of mid-low rectal cancer.Methods Both TRUS and MR were performed prior to surgery in 111 patients with mid-low rectal cancer.The CRM was evaluated and compared with the postoperative pathologic findings.Results The accuracy of TRUS and MR for CRM was 91.9%(102/111) and 85.6%(95/111),respectively,there was no statistical difference between them (P =0.137).Their specificities were 94.0% (79/84)and 84.5% (71/84),there was statistical difference between them(P =0.046).The consistency of the results between TRUS and pathology was better than that between MR and pathology(Kappa1 =0.783,Kappas =0.652).Conclusions TRUS is proved to have an important diagnostic value for CRM of mid-low rectal cancer.

Objective To explore ultrasonic image for the normal anatomy of the larynx,and provide the basis of ultrasonic diagnosis in laryngeal diseases.Methods Ultrasound anatomy for the larynx was established by way of comparing the structures of four corpses and ultrasonic imaging of the larynx of normal control group.Results Ultrasonic image for the normal anatomy of the larynx was established by comparing the anatomy tomography of corpses and ultrasonic imaging of the larynx of normal control group.Conclusions Ultrasonography could be applied in the examination of the laryngeal diseases as it could show unambiguous ultrasonic imagings of the larynx,and adding an important complementary technique to clinical medicine.
