Before operative treatment is performed, colonic and anorectal physiologic studies, including measurement of anorectal inhibitory reflex, anal canal pressures, radio-opaque marker colonic transit study, and video defecography, should be performed.
Defecography is an x-ray of the anorectal area that evaluates completeness of stool elimination, identifies anorectal abnormalities, and evaluates rectal muscle contractions and relaxation.
At the forefront of radiological technology, Manhattan Diagnostic Radiology was also among the first practices to introduce Breast MRI in an outpatient setting, and is one of the only practices to routinely conduct complex MR Defecography studies in the entire Tri-State Area.
