Review
The superior tissue contrast and flexible imaging planes afforded by magnetic resonance imaging (MRI) versus competing technologies permit optimal depiction of the pelvic viscera. Targeted protocols developed for specific pelvic visceral organs highlight important anatomic features that may not be imaged by other modalities. Therefore, a solid understanding of normal and variant pelvic anatomy is crucial for appropriate interpretation of pelvic MRI studies. This article discusses the protocol strategies and relevant anatomy with commonly encountered anatomical variants in a segmented/organ-specific manner, using gender as a broad split given the substantial variance in relevant organs.

The sectional anatomy of the pelvic floor was studied in plastinated sections of adult pelves by computed tomography and by magnetic resonance imaging. In sectional anatomy, the levator ani is composed of three portions that can be clearly distinguished by their planes of cleavage and by the course of their fiber bundles. No muscular connections are found between the levator ani portions and the pelvic organs. The fascia of the levator ani in always interposed between the muscle and the pelvic organs. The sectional anatomy of the sphincter ani externus reveals a subdivision into a subcutaneous and a deep portion. Although the puborectalis portion of the levator ani and the deep portion of the sphincter ani externus are more or less continuous, in sectional anatomy they can be distinguished due to their different origins and attachments.

Review
Magnetic resonance imaging (MRI) is often "one stop shop" for evaluating female pelvic masses that helps in diagnosis, staging, and restaging of these tumors. A pelvic mass can arise from any tissue present within the pelvis. Although most masses in the female pelvis arise from the reproductive organs, masses may also arise from the gastrointestinal tract, urinary system, adjacent soft tissues, peritoneum, etc. It may not always be possible to determine the site of origin or distinguish these masses based on imaging characteristics. However, familiarity with the clinicopathologic and MRI features of most common pelvic masses helps in narrowing the differential diagnosis. Diagnosis of these masses needs a holistic approach as required for any tumor including clinical history, laboratory data, and imaging characteristics. We focus on MRI characteristics of commonly encountered pelvic masses. A compartmental imaging approach is discussed in this article that helps in identifying and characterizing these masses.

We report on a virtual anatomical preparation of the abdomen and pelvis of the Visible Human Female (VHF) for laparoscopic surgery training. The detailed cross-sectional image data set from the U.S. National Library of Medicine was used as the basis to build an exemplary model of the female abdomen and pelvis. Segmentation software was developed to delineate organ outlines and more than 300 structures of interest, including organs, blood vessels, bones, muscles, and ligaments, have been segmented and three-dimensionally reconstructed. Analyzing the normal anatomy we found several variations and pathologies of the VHF, such as missing muscles (gemellus superior, psoas minor), additional veins as well as spondylophytes (vertebral column, pubic bone), and colon diverticula. The complete data set may be viewed on the home page of the project (http://www.vision.ee.ethz.ch/projects/Lasso/start.html).

Review
A working knowledge of anorectal and pelvic anatomy is crucial for the understanding of normal function, pathogenesis and surgical treatment of anorectal diseases. In a field of unlimited details and varying definitions, our goal is to provide an overview of anatomic concepts relevant for the practical management of patients.

Computed tomography (CT) remains a valuable technique in the assessment of the female pelvis. The CT appearance of the normal ligamentous, vascular, and visceral anatomy of the female pelvis can be confusing. Newer high-resolution CT scanners combined with mechanical intravenous contrast medium injectors and thinner sections have substantially improved the imaging of female genital tract anatomy. In addition to the cardinal, uterosacral, and round ligaments, the ovaries and their ligamentous attachments, as well as the blood supply to the female internal organs, can now be visualized. Inferior-to-superior image acquisition following bolus administration of intravenous contrast material with an angiographic injector facilitates precise identification of the uterine artery and its relationship to the pelvic ureter and the vascular plexus supplying the vagina, ovaries, and uterine body. Ideally, familiarity with variations in the CT appearance of normal female pelvic anatomy will enable more accurate evaluation of pelvic abnormalities.

Traumatic hemipelvectomy is rare, and is usually accompanied by injury to the genito-urinary tract and bowel. Recently, there have been an increasing number of reports of patients who have survived this injury, probably as a result of improved early care. We report three such cases and review the literature. The amputation wound should not be closed initially; early re-exploration to remove any dead tissue is indicated, and this should be repeated as necessary.

The clinical and radiological features of five patients with hydatid cyst of the pelvis are presented. The cysts were found in the following sites: the broad ligament, the pararectal soft tissues, the greater omentum, the ala of the sacrum and in the retrovesical space. Hydatid disease should be considered in the differential diagnosis of unusual cystic swellings in the pelvis, particularly in patients who have lived in endemic areas.

Comparative Study
The sectional anatomy of the pelvic connective tissue was studied in plastinated sections of fetal and adult pelves, by computed tomography and by magnetic resonance imaging. The comparative study of the different specimens shows that the pelvic connective tissue consists of three compartments: a presacral compartment, a perirectal compartment, and a paravisceral compartment. The content and the borders of the compartments are described. Furthermore the pelvic fasciae and the pelvic ligaments are studied within the different specimens. A thin pelvic visceral fascia can only be found around the perirectal compartment. In tomographical anatomy the so called supportive ligaments of the uterus are only composed of the round ligaments and the sacrouterine ligaments.
