Pelvis supine

MRI of the female pelvis is performed after 5 h of fasting and with prior intramuscular injection of peristaltic inhibitors to minimize artifacts due to bowel movement. The patient lies on her back in a supine position with a pelvic, torso, or cardiac coil attached around her pelvis. The coil ideally covers the region from the symphysis pubis up to the renal hilum. Depending on the woman s height, upper coverage may be lower and require secondary adjustment of the... 

As mentioned above, MR pelvimetry is usuallyper-formed in the supine position. Tl-weighted gradient-echo sequences of the maternal pelvis are acquired with the body coil in axial, sagittal, and oblique (in a plane through the symphysis and sacral promontory) orientation as shown in Fig. 14.2. 

The child is encouraged to lie on the table in a supine position. The older child s mid-sagittal plane should run parallel with the long axis of the examination table if the bucky is to be used. The legs should be straightened and internally rotated from the hips until both knees are supported in the AP position with the patella lying in a central position over the femoral condyles this often results in the big toes touching. The anterior superior iliac spines should be equidistant from the film to prevent rotation of the pelvis (Fig. 2.1). 

If patient is symptomatic or he/she requires i.v. injection of contrast medium for any other clinical reason, mAs should be set at the standard value for an abdomen and pelvis CT scan. In order to reduce dose delivery, patient might be scanned in prone position using a low or an ultra-low dose protocol, and at full dose only in supine scan when contrast medium is injected. 

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. 

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. 

The primaiy flexors are the psoas and iliacus. This may be tested in a seated position with the patient lifting the knee while the examiner stabilized the pelvis and evaluates strength with the application of graded resistance at the knee. It may also be evaluated with the patient supine and the knees extended. 

Patient position supine. One version has the patient completely on the table. Another version has the patient with head, neck, trunk, and pelvis on the table but either the legs are able to hang off table or the legs are put into this position by a drop leaf on the table...
