On [[thoracic]] [[MRI]], thymoma is characterized by increased [[heterogeneous]] signal on T2WI.

==MRI==
* [[Magnetic resonance imaging|MRI]] is usually performed in [[Patient|patients]] with suspected [[vascular]] [[Invasive (medical)|invasion]] in which [[iodine]] [[contrast]] cannot be tolerated.
*Magnetic resonance imaging (MRI): An MRI uses magnetic fields but it is a different type of image than what is produced by computed tomography (CT) and produces detailed images of the body. Like computed tomography (CT), a contrast agent may be injected into a patient’s vein to create a better picture.
 
* Key [[Magnetic resonance imaging|MRI]] findings in thymoma are:
 
**Isotense to [[skeletal muscle]] on T1WI
**Increased [[heterogeneous]] signal intensity on T2WI
**[[Fluid]] characteristics of [[cysts]] with high [[water]] content

Overview

On thoracic MRI, thymoma is characterized by increased heterogeneous signal on T2WI.

MRI

  • Key MRI findings in thymoma are:
MRI shows the presence of an anterior mediastinal mass projecting to the left, confirmed to be thymoma.
MRI shows the presence of an anterior mediastinal mass projecting to the left, confirmed to be thymoma.[1]
MRI shows the presence of an anterior mediastinal mass projecting to the left, confirmed to be thymoma.[1]
MRI shows the presence of an anterior mediastinal mass projecting to the left, confirmed to be thymoma.
