For both doctors AP Standing, hip centered pelvis with calibration and AP Standing hip with calibration Lateral for Schabel = Cross table/shoot through Lateral for Huff = Frog leg or roll out For the calibration marker to be accurate, it must be placed on the outside of the patient’s affected leg. Placing it in between the legs, in front of or behind the leg is inaccurate. When placing the marker first find the greater trochanter. Place the marker ball on that spot. There is no wiggle room for the marker to be moved toward the front or back of the patient; however the marker may be moved upward toward the iliac crest or downward toward the knee as long as it is still in the same line front to back as the trochanter. We are measuring magnification from the OID created by the patient’s rear end and soft tissue; therefore the OID from the marker ball to the bucky must be the same as the greater trochanter to the bucky. For larger patients: Having the patient reach the hand of the affected side down and push the marker ball into their soft tissue is one way to have it be visible on a larger patient. If that doesn’t work look for any spot that you can see a tiny bit of light behind the patient, move the ball upward or downward to that spot keeping in line front to back with the greater trochanter and have the patient push the ball inward. Also you can off center the patient to give them a little more room on the affected side along with the above method. If there is still no seeing the ball, then you may have to take 2 images to get the ball on 1 and a centered pelvis on the other. The patient can be off centered pretty far as long as both hip joints are still visible on the image with the marker ball. The centered image is for the radiologist to be able to accurately read the images. 29 PPV 2013 IMAGING SERVICES LAST REVISION DATE: JUNE 2013 METASTIC BONE SURVEY ** Send to PACS in this order: LATERAL SKULL & C-SPINE Do both on 1 - 14 x 17" cassette at upright bucky, with patient sitting.

It is of importance that the spine is cleared through C7 – T1. This may be accomplished by obtaining a lateral while the physician pulls on the patient's arms or by placing the patient in a swimmer's position (the technologist may need to over penetrate the mid section of the spine in order to visualize C7 – T1). The emergency room triage physician determines the neck trauma status prior to ordering images. Upon the completion of the lateral image, the triage physician will determine whether a consultation is necessary with the radiology staff. When it is determined that consultation is needed, the radiologist or resident will report to the emergency room for assistance and decide what further views are to be taken. 34 PPV 2013 Policy for Clearing Cervical Spine: When cervical spines need to be cleared, the AP, Lateral, and odontoid (and swimmer's view if necessary) should be shown to a radiology resident or staff. If the radiology resident or staff feels that it is safe to go ahead with flexion and extension views, this should be documented by that individual in the patient's chart. If a cervical collar is present, it may then be removed and lateral flexion and extension views of the cervical spine are done with the patient flexing and extending unassisted. If the C7 – T1 level is not demonstrated on the routine views, swimmer's lateral should be taken as well during the flexion and extension views. In the uncooperative or incoherent patient who has normal AP, lateral, and odontoid views, it will be necessary for the referring attending staff or house staff to position the patient for the flexion and extension views. Clearance under fluoroscopy is not to be done. POST TRAUMA C-SPINE: FOR CLEARING C-SPINE (3 images) AP Cross-Table Lateral Odontoid *perform a swimmers view if unable to see C7 – T1.

If the request cannot be verified or there is a problem concerning request vs. diagnosis, a radiologist must be consulted, and an appropriate notation shall be made in QDOC . RADIATION PROTECTION: 49 PPV 2013 A. Meticulously collimate to exact size of cassette or anatomical part being radiographed if smaller. B. Use gonadal shielding on all patients through age 55 unless shielding will obscure the area of interest or unless noted on the Physician’s Order to not use shielding. If there is a question as to when to shield, check with the Lead Technologist or the resident on call. If a shield is not used, the appropriate label "NGS" (no gonadal shielding) should be used. Should there be a possibility that the patient is pregnant and the fetus will be within 12 inches of the primary beam, use the pregnant patient protocol and fill out the appropriate paperwork. QUALITY ASSURANCE: A. All radiology consultation requests are reviewed for completeness and accuracy by quality control persons. Those persons being the Lead Technologist, modality Supervisor, radiology residents, or radiologists. B. Finished radiographs are checked for quality, completeness, proper patient identification, lead markers, performing technologist's lead markers on image, artifacts, and proper exposure. 50
