Dialysis is not indicated immediately after administration of nonionic contrast agents in patients with end-stage renal disease treated by maintenance dialysis.

Objective: This study was undertaken to determine the necessity of immediate dialysis after intravascular injection of contrast material in patients with end-stage renal disease who are being maintained on hemodialysis. Although many physicians support this practice, we could find no reports of studies to confirm or refute its necessity.

Subjects And Methods: We studied 10 patients being treated with hemodialysis who were undergoing 11 diagnostic procedures that required intravascular contrast material.

Radiologic anatomy--a credit course for first-year medical students.

Diagnostic radiology should assume a more prominent role in medical student education. We have developed a 4-year plan for radiologic education at the University of Florida. The initial step in this plan is a required credit course in radiologic anatomy given in the first semester.

Correlation of lymphangiography, computed tomography, and laparotomy in the staging of Hodgkin's disease.

Purpose: To determine the predictive value of lymphangiography and computed tomography of the abdomen and pelvis for infradiaphragmatic involvement of Hodgkin's disease.

Methods And Methods: We retrospectively reviewed the findings on 125 patients with Hodgkin's disease treated at the University of Florida who underwent lymphangiography and staging laparotomy; 33 patients also underwent computed tomography of the abdomen and pelvis. The positive predictive value and negative predictive value were calculated for both studies.
