title: Use of ultrasound scan in prostatic I-125 implantation.
abstract: The average dimension of prostate was measured by transabdominal ultrasonography preoperatively to compare with direct intraoperative measurements in 28 patients undergoing suprapubic I-125 seed implantation for the treatment of prostatic cancer. A highly significant correlation (r = 0.932) was found between these two measurements. Transabdominal ultrasonography is a relatively simple and accurate non-invasive method of determining the number of I-125 seeds needed to implant the patient with prostatic malignancy.
