Overview

MRI is not commonly performed but it is considered the modality of choice for adenomyosis. findings for other conditions may also be seen but may not be as reliable as other imaging studies. MRI can assist in furthering diagnosis metastasis.

MRI

MRI Findings
Underlying Cause MRI Findings
Endometrial Polyps [1]
Case courtesy of Dr Ammar Haouimi, Radiopaedia.org, rID: 70016
  • hypointense intracavitary masses
  • surrounded by fluid and endometrium
Adenomyosis [2]
Case courtesy of Dr Varun Babu, Radiopaedia.org, rID: 43504


  • Diagnosis of choice; sensitivity of 78-88% and specificity of 67-93%
  • thickening of the junctional zone ≥12 mm (normal is up to 5 mm)
  • appears as an ill-defined region of thickening
Leiomyoma [3]
Case courtesy of Dr Chris O'Donnell, Radiopaedia.org, rID: 22883

  • only used for complex cases
  • may accurately determine size and location
  • appear hypervascular
  • helpful when surgery is considered or when trying to differentiate from fibroids
Malignancy [4]


Case courtesy of Dr Bahman Rasuli, Radiopaedia.org, rID: 83200


  • MRI may be helpful in improving accuracy for determining metastasis
  • normal tissue enhances more than malignant tissue
PCOS [5]



Case courtesy of Dr Mostafa El-Feky, Radiopaedia.org, rID: 53010

  • not a routine examination for PCOS
  • follicles will be seen on MRI
Endometrial Causes [6]



Case courtesy of The Radswiki, Radiopaedia.org, rID: 11397

  • Endometrioma appears hyperintense; the presence of hemorrhage results in a hypointense image
