Instructions And Patient Preparation<\/h3>\n
\n
Instructions<\/dt>\n
• Have patient empty bladder before scanning
• Optional: Patient could take a Fleet enema prior to appointment
• NPO for 4 hours prior to study recommended (reduces bowel motion)
• Small field of view imaging must be angled to the mass
• MD to check for Axial and Coronal Oblique angulations (true to rectal mass)<\/dd>\n
