Name of projection	Renal - Supine Abdomen
Area Covered	Kidneys, Ureters, bladder
Pathology shown	radioopaque renal stones ( PT Should have CT scan on initial presentation to prove stones are radio-opaque, when lloking for stones, role of plain xray is to monitor position of stones only, not initial diagnosis)
Radiographic Anatomy	Abdomen Radiographic Anatomy
IR Size & Orientation	35 x 43 cm Portrait D.R. may cover 43 x 43 cm
Film / Screen Combination	Regular (CR and DR if available)
Bucky / Grid	Moving or Stationary Grid
Filter	No
Exposure	75 kVp 35 mAs
FFD / SID	100 cm
Central Ray	Directed to the midsaggital plane at the level of the iliac crests Perpendicular to the IR
Collimation	Centre: To the midsaggital plane at the level of the iliac crests Shutter A: Open to include the pubic symphysis inferiorly Shutter B: Open to include the lateral skin margins if possible
Markers	Inferior and Lateral Marker orientation AP
Shielding	Gonadal for males (check your department's policy guidelines)
Respiration	On suspended inspiration (check your departmental technique protocol)
Positioning	Patient is supine and positioned without rotation of the torso Ensure there are no artefacts such as zips or buttons over the area being imaged Centre the midsaggital plane of the patient to the midline of the IR Patient's arms slightly abducted from the torso
Critique PACEMAN	Positioning No rotation as evidenced by symmetrical iliac wings the obturator foramina are both open and symmetrical the sacrum is centred in the pelvic inlet the pedicles of the vertebrae are the same distance from the spinous processes on each side Area Covered The diaphragm to pubic symphysis Collimation Centre:L4 Lumbar vertebra, which is at the level of the iliac crests Shutter A: Open to include the pubic symphysis inferiorly and kidneys superiorly Shutter B: Open to include the lateral renal outlines Exposure There should be adequate exposure and no patient motion so that the following anatomy is demonstrated the outline of the psoas muscles the outline of the kidneys skeletal structures such as the posterior ribs, vertebrae and pelvic anatomy
