What could cause lesions on the spleen?

Etiologies for multifocal splenic lesions include infectious and inflammatory processes, primary vascular and lymphoid neoplasms, metastatic disease, vascular processes, and systemic diseases. There is often overlap in the imaging appearance alone, so the clinical setting is very helpful in differential diagnosis.

What are the characteristics of MR imaging of the spleen?

The MR imaging characteristics of the spleen are unique with a large fractional heme content characterized by long T1 and T2 (lower in signal intensity than the liver on T1-weighted images and higher on T2-weighted images) (, 1,, 2 ).

What kind of MRI is used for liver and spleen?

A typical MRI protocol includes breath-hold T2- and T1-weighted (T2w and T1w) imaging, and chemical shift imaging for hepatic steatosis detection.

Extramedullary hematopoiesis is a compensatory response to deficient bone marrow cells. It predominantly affects the spleen and liver. Although it usually shows diffuse infiltration microscopically, there may be focal masslike involvement of the liver and spleen. The signal intensity of the mass depends on the evolution of the hematopoiesis.

How is MR imaging used to diagnose spleen disease?
