Background:
This study aimed to evaluate the accuracy of functional cine-MRI in detecting abdominal adhesions.
Methods:
For this study, 89 consecutive patients with adhesion-related complaints after previous abdominal surgery underwent preoperative workup including cine-MRI in transverse and sagittal orientations for a dynamic examination of an induced visceral slide. An abdominal map consisting of nine segments was created to document the location and extent of the adhesion. Cine-MRI and intraoperative findings were correlated.
Results:
A total of 59 laparotomies and 30 laparoscopies were performed. Four cases required open surgery due to severe adhesions. The use of cine-MRI scan for the detection of adhesions showed an overall accuracy of 90%, a sensitivity of 93%, and a positive predictive value of 96%. The stronger the adhesions, the more accurate the scan findings. Of 44 patients with second-degree MRI scan findings, 50% had second-degree intraoperative findings. Of 35 patients with third- and fourth-degree adhesions on MRI scans, 74% had exactly the same intraabdominal findings at surgery. The MRI scan showed adhesions located in the small intestines (75%), large intestines (35%), abdominal cavity (42%), and reproductive organs (32%). Intraoperatively, adhesions were found in the small intestines (70%), large intestines (40%), abdominal cavity (42%), and reproductive organs (28%).
Conclusions:
Cine-MRI provides valid preoperative information with respect to extent, location, and strength of intraabdominal adhesions. Cine-MRI is a good alternative for diagnosing abdominal adhesions because objective findings of the scan and intraoperative findings correlate very well with each other.
Insights
Functional cine-magnetic resonance imaging (cine-MRI) accurately detects abdominal adhesions, offering valuable preoperative insights into their extent and severity. This imaging technique correlates well with surgical findings, aiding diagnosis.
Area of Science:
- Radiology
- Gastroenterology
- Surgical Oncology
Background:
- Abdominal adhesions are a common complication of abdominal surgery.
- Accurate preoperative detection of adhesions is crucial for surgical planning and patient management.
Purpose of the Study:
- To evaluate the diagnostic accuracy of functional cine-magnetic resonance imaging (cine-MRI) in detecting abdominal adhesions.
- To correlate cine-MRI findings with intraoperative findings in patients with adhesion-related complaints.
Main Methods:
- Eighty-nine patients with post-surgical adhesion complaints underwent preoperative cine-MRI.
- Dynamic visceral slide examination was performed in transverse and sagittal planes.
- An abdominal map documented adhesion location and extent; findings were correlated with intraoperative results.
Main Results:
- Cine-MRI demonstrated an overall accuracy of 90% for detecting adhesions, with 93% sensitivity and 96% positive predictive value.
- Scan accuracy increased with adhesion severity; 74% of severe adhesions (third/fourth-degree) on MRI matched intraoperative findings.
- MRI accurately localized adhesions in the small intestines (75%), large intestines (35%), abdominal cavity (42%), and reproductive organs (32%).
Conclusions:
- Functional cine-MRI is a valid tool for preoperative assessment of intra-abdominal adhesions, providing information on extent, location, and strength.
- Cine-MRI findings correlate well with intraoperative observations, establishing it as a reliable alternative for diagnosing abdominal adhesions.
