Study Notes
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.
