Study Notes

Camp Coventry Method

Prone position with femur parallel to image receptor (IR) accurately demonstrates intercondylar fossa of the knee.
Alternative methods include Beclere (supine) and Holmblad (kneeling or standing).

PA Projection of Patella

Proper heel rotation is 5 to 10 degrees laterally to ensure the patella is parallel with IR.

Lateral Radiograph of Leg

Tibia appears partially superimposed over the fibula in a true lateral position; only proximal and distal ends should align.

Central Ray for PA Chest

Direct the central ray to the midsagittal plane, 18-20 cm below the vertebral prominens for optimal results.

Esophagram and Varices

The Valsalva maneuver helps demonstrate esophageal varices during an esophagram, as it causes increased venous pressure.

Air-Fluid Levels in Chest Projection

Use a central ray parallel to the floor for anteroposterior (AP) semierect chest projection to visualize air-fluid levels.

Central Ray Location for AP Chest

The jugular notch serves as the landmark for proper central ray positioning, located 3-4 inches above T7.

Demonstrating Left Kidney in IVU

Utilize a 30-degree right posterior oblique (RPO) position to display the left kidney in profile.

Pedicle Location in Oblique Lumbar Spine

Pedicles are centrally located on lumbar vertebral bodies in a 45-degree oblique view; misalignment indicates over or under-rotation.

Clay Shoveler's Fracture

Best visualized on a lateral cervical projection; occurs due to hyperflexion and avulsion of cervical spinous processes.

Correcting Sagging in Lateral Lumbar Spine

Assess line connecting spinous processes relative to tabletop; some adjustments may involve a 5-degree caudal angle.

Lateral Knee Image Correction

To superimpose femoral condyles, position the patella closer to the IR; avoidance of cephalic angulation recommended.

Showcasing Right Kidney in Profile

Achieved with a 30-degree left posterior oblique (LPO) position during imaging.

Barium Requirement for Small Bowel Series

Administer two 250 cc cups of barium sulfate suspension when no preceding upper GI series is conducted.

Body Habitus and Gallbladder Positioning

Order from highest to lowest gallbladder position: Hypersthenic, Sthenic, Hyposthenic, Asthenic.

Anteroposterior Hip Radiograph

No corrections needed if femoral neck is clear, greater trochanter is laterally visible, and lesser trochanter is superimposed.

Stomach Projection and Duodenal Bulb

The right anterior oblique (RAO) position in posteroanterior projection shows the duodenal bulb filled with barium and free of superimposition.

Location of Urinary Bladder in Retrograde Pyelogram

Located midline, just superior to the pubic symphysis.

Elbow Position for Radial Neck Visualization

Lateral oblique position effectively demonstrates the radial neck without ulnar superimposition.

Myelography Contraindication

Presence of blood in cerebrospinal fluid indicates irritation which can be exacerbated by contrast medium.

Shoulder Image Quality Assessment

Both internal rotation images exhibit inadequate rotation; neither shows the lesser tubercle in profile.

Anteroposterior Ankle Projection

No correction is needed if medial mortise joint is open and lateral mortise joint is closed.

Medial Oblique Foot Correction

Increase medial rotation to open joint spaces between third and fifth metatarsals for improved imaging.

Imaging Duodenal Bulb Location

The duodenal bulb appears as an arrowhead-shaped structure adjacent to T12 and L1 on the PA Small Bowel image.

Correcting Lateral Scapula Image

Decrease patient obliquity for proper superimposition of the lateral and vertebral borders of the scapula.

Anteroposterior Rib Projection Correction

Rotate the patient to the right if the left sternoclavicular joint is shown without vertebral column superimposition.

Evaluating Coronoid Process

The medial oblique elbow projection showcases the coronoid process distinctly.

Rotating Patient for Lateral Femur

If the patient rotates anteriorly, the medial condyle becomes anterior to the lateral condyle, indicating excessive rotation.

Acanthion Position for PA Mandible Projection

Central ray should be centered to the acanthion for optimal mandibular rami demonstration.
