Skull Lateral View (Radiography Positioning)

Summary

Welcome to our radiography series focusing on skull imaging. Today's episode explores the 'Skull Lateral View,' detailing necessary patient preparations, including the removal of any metallic materials and positioning for accurate image capture. We discuss the positioning techniques in both supine and prone orientations, emphasizing correct alignment for clear and precise radiographic results. Indications for this view include diagnosing fractures, overgrowths, cysts, or foreign bodies within the skull. This video aims to enhance understanding and implementation of proper techniques for effective skull radiography.

Takeaways

• 📚 The video discusses the 'Scalp Series' focusing on the 'Scalp AP View', which is a literal view of the scalp for radiography positioning.
• 👨‍⚕️ Patient preparation involves removing metallic materials from the scalp and surrounding areas, including hair clips, hair bands, and jewelry.
• 🛏️ The patient is positioned in a prone position with the head turned to one side to achieve a true lateral position for the scalp.
• 🔍 Indications for the Scalp AP View include fractures of the skull bone, any overgrowth or cyst in the scalp region, and foreign bodies within the scalp area.
• 📐 The patient's head should be positioned over the center line of the examination table to ensure a proper image capture without any part cuts.
• 👂 The external auditory meatus (ear canal) should be superimposed over the contralateral one to check the patient's proper positioning.
• 📏 The cassette width should be set to 2 inches above the vertex to ensure a proper image of the entire scalp without any part being cut off.
• 📏 The center should be positioned at 2.5 cm anterior and 2.5 cm superior to the 'E' to get a perpendicular central line for the true lateral view.
• 🚫 The patient should be instructed to avoid movement during exposure to capture a proper image.
• ⏱️ The exposure chart for the Scalp AP View includes settings such as 200 mAs, 40-50 kVp, and an exposure time of 0.20-0.25 seconds.
• 📈 The radiographic reference for the Scalp AP View includes visualizing the frontal bone, parietal bone, temporal bone, orbit fossa, nasal fossa, and the zygomatic and maxillary bones.

Q & A

What is the subject of the video series mentioned in the transcript?

The subject of the video series is skull radiography positioning, specifically focusing on a series called 'Skull Series'.

What type of view is being discussed in the video?

The video discusses the 'Skull Literal View', also known as the 'Skull Lateral View'.

How is the patient positioned for the Skull Literal View?

The patient is positioned in a prone position with the head turned to one side to achieve a true lateral position.

What should be removed from the scalp and surgical region before radiography?

Metallic materials such as hair clips, hair bands, and any jewelry should be removed from the scalp and surgical region.

What are the indications for performing a Skull Literal View?

Indications include fractures of the skull bone that are not visible on AP view, any overgrowth or cyst in the skull region, and foreign bodies within the skull region.

How should the patient's head be positioned to achieve a true lateral view?

The patient's head should be positioned so that the center line is over the center line of the examination table to achieve a true lateral view.

What is the significance of the inner table line being perpendicular to the table top?

The inner table line being perpendicular ensures that the patient's skull is properly positioned, allowing for a proper image capture without any part being cut off.

What is the recommended distance for the X-ray beam from the vertex and the posterior aspect?

The X-ray beam should be 2 inches above the vertex and 2 inches behind the external auditory meatus.

What is the exposure chart for the Skull Literal View?

The exposure chart includes settings such as 200 mA, 40 to 50 kV, exposure time between 0.20 to 0.25 seconds, and an FFD (Focal Film Distance) of 100 cm.

What are the anatomical landmarks visualized during the Skull Literal View?

Anatomical landmarks include the frontal bone, zygomatic bone, parietal bone, temporal bone, orbit fossa, nasal fossa, and the maxilla and mandible.

What is the importance of ensuring no movement during exposure?

Ensuring no movement during exposure is crucial for capturing a clear and proper image of the skull.

What are the typical film sizes used for the exposure chart in the Skull Literal View?

The typical film sizes used are 10 x 12 inches or 12 x 15 inches.
