Sliding multislice MRI for abdominal staging of rectal gastrointestinal stromal tumours

Anorectal gastrointestinal stromal tumours (GISTs) are uncommon mesenchymal neoplasms. The objective of this report was to demonstrate the value of sliding multislice (SMS) as an upcoming method of continuously moving table MRI, providing detailed abdominal staging of rectal GISTs. Integration of SMS into a high-resolution pelvic MR imaging protocol allows for both detailed assessment of rectal GISTs and depiction of the entire abdomen with high image quality. The staging of liver, malignant lymph nodes and bone metastases is now possible, prolonging pelvic MRI for only one minute.
