Performance Comparison of 1.5-T Endorectal Coil MRI with 3.0-T Nonendorectal Coil MRI in Patients with Prostate Cancer

摘要

Prostate cancer is the second most common cause of cancer death among American men. The American Cancer Society estimated that 233,000 new cases of prostate cancer would be diagnosed in 2014, and approximately 29,480 men would die of the disease (1). Magnetic resonance (MR) imaging (MRI), with excellent soft-tissue contrast, provides high resolution images of the pelvis for use in prostate cancer management (2). The use of an endorectal coil is an essential part of the prostate 1.5-T MRI protocol in the clinical diagnosis of prostate cancer (3). An endorectal coil is inserted tightly against the prostate during the MRI examination to increase image resolution and improve staging accuracy (4).
