Abstract:
It has been reported that MR imaging of the spleen is unsuccessful in detecting focal lesions because there is not a significant difference in relaxation times between most tumors and surrounding normal spleen. We reviewed the MR imaging of 15 patients (5 cysts, 2 abscesses, 1 hemangioma, 5 malignant lymphomas, 2 metastatic tumors). In all cases, the difference in signal intensities between splenic tissue and mass lesions permitted detection of splenic lesions on MR images. But, malignant lesions were less visible than benign lesions.
Insights
Magnetic resonance (MR) imaging can detect spleen lesions by differences in signal intensity, contrary to previous reports. However, malignant spleen tumors were less visible than benign lesions on MR images.
Area of Science:
- Radiology
- Medical Imaging
- Oncology
Background:
- Magnetic resonance (MR) imaging has limitations in detecting focal splenic lesions due to similar relaxation times between tumors and normal spleen tissue.
- Previous studies suggested MR imaging is often unsuccessful for spleen lesion detection.

Radiological Investigation II: MRI and Ventilation Perfusion Scan
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
