Overview
CT scan may be helpful in the diagnosis of intussusception. CT scan maybe used when other image modalities like x-ray and ultrasound have not given positive results but suspicion of intussusception is high. CT scan is also used to characterize the pathology (lead point) once intussusception has been diagnosed by ultrasound. CT scan has its drawbacks in children as it is time consuming and leads to substantial radiation exposure.
CT
- CT scan may be helpful in recognizing the case of intussusception[1]
- CT scan cannot be used to treat/reduce the intussusception
- Drawbacks of using CT scan in children are as follows:
- May require sedation which can be very time consuming and may delay treatment
- Exposure to radiation is substantial
- CT scan is used in patients when other imaging modalities are unable to recognize intussusception
- CT scan can be used to recognize the lead point[2]
- CT scan is also used to characterize the pathology once intussusception has been diagnosed by ultrasound
