FIGURE 7.3. Adipose tissue thickness in people in the general population (solid bars) and in obese persons (dashed bars). Adipose tissue thickness was measured by ultrasound measurements (not by the usual technique of skinfold measurements) at the gluteal site (G), femoral site (F), hypogastric site (H), and epigastric site (E). The epigastric site that was used was one-third the distance down from the tip of the sternum to the umbilicus. This site was somewhat thicker in men than in women. The femoral site was one-third the distance down from the anterior superior Uiac spine (wide part of the pelvis) to the patella (knee). This site was much thicker in women than in men. Biopsies were also taken at the indicated sites and examined imder the microscope to acquire fat cell size. (Redrawn with permission from Krotkiewski et ah, 1983.)... 

My technique for embolization of uterine fibroids starts with placing a flush catheter that allows a contralateral approach (VCF or Omni Flush catheter) into the aorta and positioning it just below the level of the renal arteries. The image intensifier is centered over the pelvis and a angiogram is performed which allows for visualization of ovarian artery collaterals, and provides visualization of the iliac anatomy (Fig. 10.3.6a). The flush catheter is then positioned... 

With this practical application in mind, we arranged the chapters mainly according to the different disorders of the female pelvis and not with regard to technical aspects of the imaging modalities or strictly anatomic considerations. The main chapters dealing with the different disorders are preceded by an interesting presentation of a new interpretation of the anatomy of the female pelvis and a general introduction to state-of-the-art CT and MRI techniques. 

The proposed technique is based on lever arm principal correction. It combines anterior rotation of the pelvis and posterior ranslation of the lumbar spine.

CT technique for a colon study should be tailored according to clinical indication. If MDCT is performed for staging of a known CRC and for follow-up, then a contrast-enhanced study of the abdomen and pelvis should be performed no specific colon preparation is required, and the examination can be considered as a routine abdominal study. On the other hand, if a diagnosis of either a CRC or a precursor (adenomatous polyp) (Fig. 31.1) is concerned, then CTC is the exami-... 

We were trying to apply this technique in a variety of different settings. We realized the advantage of C-arm CT in case of aortic dissection in order to follow the course of the catheter through the false and true lumen (Fig. 41.1). Also, in case of both sided hip en-doprotheses where beam-hardening artifacts between the two metal pieces hinders conventional CT visualization of the structures in the small pelvis, C-arm CT was able to demonstrate the proximity of the internal iliac... 

In 1958, Creech et al. used extracorporeal circulation to perfuse anticancer drugs locally in organs which could be separated from the systemic circulation. They attempted active intervention to eradicate all tumor cells and to decrease systemic adverse reactions more completely than can be achieved by arterial infusion therapy. This technique has been established primarily for primary or recurrent tumors located in the pelvic area. Up to now the technique of isolated perfusion has been established for different areas of the body such as the limbs, the liver, the thoracic region, the abdomen or the pelvis. 

The counterstrain tender points of the lumbar spine are named for the dysfunctional lumbar vertebrae. Anterior tender points are treated with the patient supine and posterior tender points are treated with the patient prone. Many of the counterstrain techniques for lumbar somatic dysfunctions are facilitated by slight rotation of the patient s thighs and pelvis, and by resting some part of the patient s leg on the physician s thigh or knee. 

Facilitated Positional Release Techniques for the Sacrum and Pelvis... 

This chapter describes facilitated positional release (FPR) techniques for the sacrum and pelvis. The principles of FPR apply the lumbosacral spine is flattened by placing a pillow under the abdomen of the prone patient, the involved area is placed into the freedoms of motion of the involved joint or the muscles being treated are shortened, and a facilitating force is added, either compresson or torsion. 

This chapter describes Still techniques for treating somatic dysfunctions of the sacrum and pelvis. There are several systems of diagnosis, but the techniques described in this chapter are related to the systems that are used in this textbook. There are also seated techniques described, albeit less effective than the supine ones described. Because of the complexity, interested students should refer to Dr. Van Buskirk s more thorough book and chapters for other techniques and diagnoses.
