Summary
Superparamagnetic contrast agent ENDOREM significantly improves liver lesion detection compared to unenhanced MRI. ENDOREM-enhanced MRI shows comparable sensitivity to CTAP for preoperative staging of liver tumors.
Area of Science:
- Radiology
- Medical Imaging
- Oncology
Background:
- Accurate detection of liver metastases is crucial for treatment decisions in cancer patients.
- Conventional contrast-enhanced CT and unenhanced MRI have limitations in detecting small liver lesions.
- Intraoperative ultrasound and CTAP offer high sensitivity but are invasive.
Purpose of the Study:
- To evaluate the efficacy of the novel superparamagnetic MR contrast agent ENDOREM for liver lesion detection.
- To compare ENDOREM-enhanced MRI with unenhanced MRI and CTAP in preoperative staging of liver tumors.
Main Methods:
- Utilized superparamagnetic MR contrast medium ENDOREM.
- Performed MRI scans before and after ENDOREM administration.
- Compared lesion detection rates with unenhanced MRI and CTAP.
Main Results:
- ENDOREM significantly increased the number of detected liver lesions compared to unenhanced MRI.
- ENDOREM-enhanced MRI demonstrated sensitivity comparable to CTAP for lesion detection.
- Improved delineation of the hepatic vascular system was observed.
Conclusions:
- ENDOREM enhances liver lesion detection and characterization in patients with primary tumors.
- ENDOREM-enhanced MRI is a valuable tool for preoperative staging of liver tumors.
- This technique offers a non-invasive alternative with high sensitivity for detecting liver metastases.
