Focal splenic lesions: Imaging spectrum of diseases on CT, MRI and PET/CT - 02/09/21
Highlights |
• | Computed tomography (CT), magnetic resonance imaging and positron emission tomography/CT have a complementary role in the characterization of focal splenic lesions. |
• | The majority of focal splenic lesions can be diagnosed with imaging with a high degree of confidence due to suggestive or typical features. |
• | A substantial number of focal splenic abnormalities require histopathological analysis for a definite diagnosis. |
• | Further studies are needed to elucidate the potential of radiomics and artificial intelligence in the characterization of focal splenic lesions. |
Abstract |
The spleen can be affected by a variety of diseases. Some of them are readily identified as variations of normal or benign diseases on imaging. However, for a substantial number of focal splenic abnormalities, the diagnosis can be difficult so that histopathologic analysis may be required for a definite diagnosis. In this review, the typical splenic abnormalities that can be diagnosed with imaging with a high degree of confidence are illustrated. The complementary role of computed tomography (CT), magnetic resonance imaging and positron emission tomography/CT that helps make a diagnostic approach is discussed. Finally, current applications and future trends of radiomics and artificial intelligence for the diagnosis of splenic diseases are addressed.
