Overview

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
