Application of simple-shot-radio(SSH/RAD) MR hydrography(MRH) based on SENSE in gastrointestinal tract examination / 西安交通大学学报(医学版)

Objective To evaluate the capability of SSH/RAD MRH based on SENSE to show gastrointestinal tract anatomic structure,to provide normal anatomic base for gastrointestinal tract disease diagnosis with SSH/RAD MRH and to explore the new examination method for imaging diagnosis in gastrointestinal tract disease.Methods There were 30 healthy volunteers in total including 19 male cases,11 female cases,the age ranging from 20 to 50 with the mean age as 35 year old.All volunteers were asked to drink tap water about 1000-1500mL continuously at 60 minute before examination,to drink tap water 500mL at 20 minute before examination and receive injection of 654-2 10mg in muscle at 10min before examination.MRH were performed by Philips Gyroscan Intera 1.5T superconduct MRI scanner,using SENSE technique,phased-array coil and breath hold.SSH/RAD MRH was performed after the routine abdominal MR scan was done.Results SSH/RAD MRH was successfully performed on all volunteers at one time,and the examination achievement ratio was 100%.All images were evaluated by two senior doctors using blindness method.The ratio of the good-optimal quality images was 93% and the poor-quality images was 7%.Of all images,the stomach manifestation ratio was 65%,the stomach mucous clear manifestation ratio was 80%,the duodenum manifestation ratio was 80%,the jejunum manifestation ratio was 59%,the jejunum diameter was 2-2.5cm,the ileum manifestation ratio was 21%,the ileum diameter was 1.5-2.5cm and the small intestinal mucous clear manifestation ratio was 67%;the colon manifestation ratio was 10% and the colon mucous clear manifestation was 6%.Conclusion SSH/RAD MRH based on SENSE can clearly show the outline and mucous of the stomach,duodenum and jejunum,but can not clearly show the outline and mucous of ileum and colon.The imaging examination that the colon SSH/RAD MRH combined with the routine abdominal MR scan could clearly and conveniently show the anatomical characteristics of gastrointestinal tract.It is a new imaging examination method for gastrointestinal tract examination.
