Magnetic resonance (MR) imaging is a valuable technique for the non-invasive evaluation of the female pelvic region (for example diagnosing or staging developmental anomalies, leiomyomas, adenomyosis, vaginal neoplasms, endometrial or cervical carcinoma, ovarian cysts, endometriosis, teratomas, polycystic ovaries or other ovarian masses), but also for the study of the normal anatomy of the female pelvis.
In this anatomical study, we provide the user with a friendly and dynamic tool to learn and understand the main anatomic structures of the female pelvis.

 

 

Cross sectional anatomy: Magnetic Resonance Imaging (MRI) of the female pelvic region

 

An MR was performed on a healthy woman with two kinds of weightings: axial, coronal and sagittal spin-echo T2-weighted MR images and axial spin-echo gadolinium-enhanced fat-saturated T1-weighted MR images.
DICOM images (from our PACS (Picture Archiving and Communicating System)) were exported to JPEG format and resized with Adobe Photoshop.
Interactive anatomical tools have been developed with Adobe Flash.
This anatomical atlas has been especially designed for radiologists, gynaecologists, medical students and residents.

Anatomy of the human female pelvis: how to use anatomic labels

 

The horizontal top menu (anatomical structures) allows to the user to choose the kind of anatomical labels needed to be shown on the exam:

 

  • Genital organs: uterus (with uterine zonal anatomy: endometrium, myometrium, junctional zone), cervix (central zone, cervical stroma), parametria, vagina, ovaries and adnexa with follicles
  • Urinary system including urinary bladder, ureter, urethra
  • Digestive system including rectum and sigmoid colon
  • Pelvic diaphragm
  • Pelvic girdle
  • Spaces and foramens of the pelvic region
  • Muscles
  • Arteries
  • Veins
  • Nerves
  • Pelvic measurements

The user is able to choose one of the three planes of interest (axial, coronal or sagittal) through the left vertical menu, which also provides cross references.

As the cursor is moved over a particular anatomic area of the pelvic region, this region is highlighted and labelled: peritoneal cavity, subperitoneal space and perineal region.
