Magnetic resonance (MR) imaging is a valuable technique for noninvasive evaluation of the female pelvic region (like 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 to the user a friendly and dynamic tool to learn and understand the main anatomic structures of the female pelvis.

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 as jpeg format and resized with Adobe Photoshop.
Interactive anatomical tools have been developed with the software Macromedia Flash.
This anatomical atlas has been especially designed for radiologists, gynecologists, medical students and residents.

The horizontal top menu (anatomical structures) allows to the user to chose the kind of anatomical labels he need to show 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) with the left vertical menu, which provides also cross references.
As the cursor is moved over a particular anatomic area of the pelvic region, this region is highlighted and labeled: peritoneal cavity, subperitoneal space and perineal region.
