A study of the MR imaging manifestations with injection of sedative at the buttocks in pediatric patients

Abstract

BACKGROUND:

During the MRI examination, pediatric patients sleep under the sedation so that the image artifacts caused by the patient motion could be minimized. However, the sedative injection at the buttocks might cause a difficulty in the diagnosis of the buttock diseases using the MRI manifestations.

OBJECTIVE:

This study aims to explore the imaging characteristics of MR for the pediatric patients with the sedative injected at the buttocks in order to correctly diagnose the diseases.

METHODS:

MR imaging data of 64 pediatric patients injected with the sedative at the buttocks were retrospectively collected, including 8 cases of buttock disease. The imaging manifestations were analyzed and compared.

RESULTS:

Out of 64 patients, 8 were diagnosed as the buttock diseases. MR imaging manifestations of the sedatives injected at the buttocks were the locally patchy and streaky long T1 and long T2 signals and were different from what were shown for the normal tissues and diseases.

CONCLUSION:

The sedative injected at the buttocks has the MRI manifestations different from the normal tissues and diseases. Correctly understanding the MRI manifestations for the pediatric patients with the injection of sedative at the buttocks would reduce the chances of the misdiagnosis on the diseases.
