You made it! In this series finale, we do a rapid-fire review of the "High-Yield" concepts from the entire textbook. Perfect for your final exam or board prep. A speed-run of the most critical rotation rules, angulation formulas, and image critique criteria from Chapters 1–11.

Headwork is all about lines and angles. We simplify the skull positioning lines and how to use the Petrous Ridges as your guide. The 7-degree difference between OML and IOML, using the Dorsum Sellae to check Towne method accuracy, and the "Petrous Ridge Elevator" concept for PA skulls.

How do you see a sternum through the lungs? We explain the physics behind the RAO Sternum and the specific breathing instructions for ribs. Using the "Heart Shadow" for sternum visualization, Orthostatic Breathing techniques, and distinguishing between Anterior and Posterior Oblique rib views.

It's time to meet the Scottie Dog. We break down the complex anatomy of the oblique lumbar spine and the tube angles for the sacrum. Identifying the anatomy of the "Scottie Dog," the "Downside Rule" for posterior obliques, and the correct angulation for L5-S1 spots.

Spine radiography requires precision. We discuss the geometric challenges of the C-Spine and how to get that perfect Open Mouth Odontoid. The "Goldilocks" alignment for the Open Mouth view, checking Articular Pillars for rotation, and the Swimmer's View technique.

Don't clip the hip! In this episode, we cover the essential geometry of pelvic imaging and how to ensure you've rotated the feet enough.The "Lesser Trochanter" rule for checking foot rotation, comparing Obturator Foramina for pelvic rotation, and proper abduction for the Frog-Leg Lateral.

Struggling to get that knee joint open? We break down the math and landmarks that guarantee a perfect knee X-ray every time. The "ASIS Rule" for AP Knee angulation, using the Adductor Tubercle to fix under-rotation on laterals, and checking Fibular Head superimposition.

Shoulder positioning can be tricky. In this episode, we simplify the critique process by focusing on specific bony landmarks. The "Profile Rule" for Greater vs. Lesser Tubercles, properly opening the Glenohumeral joint (Grashey Method), and the critical alignment of the Scapular Y view for dislocations.
