DIAGNOSIS OF PROSTATIC CANCER STAGE

—COMPARATIVE ANALYSIS OF TRANSRECTAL ULTRASONOTOMOGRAPHY AND MRI—

Abstract

We analyzed ultrasonic images and MRI, and compared their significance in differential diagnosis of stages B and C in eighteen cases of prostatic cancer. The following conclusions were reached :
1) In nine patients with untreated prostatic cancer, both ultrasound and MRI clearly showed the presence of primary focus and its development. Ultrasound provided more superior information than MRI about capsule invasion, but MRI supplied better data on relations between the prostate gland and surrounding organs, and between adipose tissues.
2) In nine cases of previously treated prostatic cancer, ultrasonic images generated considerably superior tomographic pictures of both primary foci and capsules.
