|
|
||||
|---|---|---|---|---|---|
| Which specific positioning error is present if the mandibular rami ar not superimposed on a lateral skull radiograph? | show 🗑
|
||||
| show | Excessive flexion at the neck, or too much angle on CR. Rotation.
🗑
|
||||
| show | In the lower 3rd of the orbits.
🗑
|
||||
| show | 3/4" anterior & 3/4 superior to EAM. Will demonstrate the anterior & posterior Clinoid process with no divergence.
🗑
|
||||
| Which skull projection best demonstrates the Sella Turcica in profile? | show 🗑
|
||||
| Which imaging modality is usually performed on neonates with a possible intracranial hemmorhage? | show 🗑
|
||||
| What are the 5 most common errors made during skull radiography? Which 2 of those are the most common? | show 🗑
|
||||
| Which skull projection best demonstrates the Clivus in profile? | show 🗑
|
||||
| show | Small focal spot.
🗑
|
||||
| show | Aligning Mid Sagittal Plane parallel to the IR is primary. The Glabella and Inion should be equal distance to the IR.
🗑
|
||||
| show | Aligning the Interpupillary line perpendicular to the IR is the primary.
🗑
|
||||
| What positioning lines can be used to position skull directly in the center of the IR for a lateral skull? | show 🗑
|
||||
| What is the general centeriong point for the CR on a lateral skull? | show 🗑
|
||||
| What can be used to assess for rotation on a lateral skull radiograph? | show 🗑
|
||||
| What can be used to asses for tilt on a lateral skull radiograph? | show 🗑
|
||||
| Why must a paient be cleared from a X-table lateral C-spine prior to performing a x-table lateral skull? | show 🗑
|
||||
| show | CR angled 15 degrees caudad to the OML. The CR should exit at the Nasion.
🗑
|
||||
| What can be used to assess that patient is in the correct position for a PA (caldwell) Axial Skull projection? What's used to assess for rotation? | show 🗑
|
||||
| show | The Reverse Caldwell. AP Axial skull. The CR is angled 15 degrees cephalic to the OML and centered at the Nasion.
🗑
|
||||
| What can be assessed on the PA Axial (Caldwell) and AP Axial (Reverse Caldwell) radiograph's to be sure the patient and CR is in the correct position? What can be done to correct it? | show 🗑
|
||||
| show | Equal distance from mid lateral orbital margins to lateral wall of cranium on each side to assess for rotation.
🗑
|
||||
| show | The OML (OrbitoMeatal Line). The Occipital bone.
🗑
|
||||
| What is a fracture that may produce an air-fluid level in the sphenoid sinus? | show 🗑
|
||||
| show | Osteolytic Neoplasm
🗑
|
||||
| What is another name for a "PIng Pong" fracture? | show 🗑
|
||||
| show | Pituitary Adenoma
🗑
|
||||
| What's another name for Osteitis Deformans? | show 🗑
|
||||
| show | Multiple Myeloma
🗑
|
||||
| Does Paget's disease require an increase in exposure factors? | show 🗑
|
||||
| show | Foramen Magnum
🗑
|
||||
| If the patient cannot flex their neck to bring the OML perpendicular to the IR, what positioning line can the technologist bring perpendicular to the IR and how much CR angle? | show 🗑
|
||||
| show | 2" superior to the EAM, halfway between the Frontal Eminence and the Inion, or $5 degrees anterosuperior (diagonal) from the TEA. For the Sella Turcica the CR should be centered 3/4" anterosuperior to the EAM.
🗑
|
||||
| Which skull positioning line is placed parallel to the IR for the SMV projection? | show 🗑
|
||||
| show | 30 degrees caudad to the OML? 37 degrees caudad.Center to the mid sagittal plane 2 1/2 " superior to the Glabella, or 1 1/2" superior to the Superciliary Arch. Through the Sellae Turcica (3/4" anterosuperior to EAM)
🗑
|
||||
| What is the Haas Method (WHich projection and CR angle)? Which level should the CR exit at? | show 🗑
