Necessity of Obtaining a Delayed Bladder Phase Scan in Follow-up CT Whole Abdomen of Non-urinary Tract Cancer Patients
Keywords:
Delayed bladder phase, CT, AbdomenAbstract
Introduction/ To explore the necessity of obtaining a delayed bladder phase CT scan in follow-up CT whole abdomen of non-urinary tract cancer patients.
Methods: The follow-up routine contrast-enhanced CT whole abdomen protocol of 505 non-urinary tract cancer patients, who had no urinary tract symptoms, were retrospectively reviewed. The CT findings of the pelvic cavity between interpretation with and without the delayed bladder phase scan were analyzed by McNemar’s test.
Results: Of the 505 patients, 241 (47.7%) were men and 264 (52.3%) were women, with a mean age of 64 years old. There was no statistically significant differences in interpretation of the CT findings between those with and without the delayed bladder phase scan (P = .063, 95% CI 0.962 - 0.997).
Conclusion: The delayed bladder phase scan had no significant yield in follow-up CT whole abdomen of non-urinary tract cancer patients who had no urinary tract symptoms.
