Your complete study guide is ready. Here's a quick orientation of what's inside:
Part 1 - Imaging Modalities: CXR, CT (with Hounsfield units and window types), MRI, Ultrasound, PET/Nuclear - including when each is used and their limitations.
Part 2 - Systematic ABCDE Approach: A structured method for reading any chest X-ray so you never miss a finding.
Part 3 - Classic Radiological Signs: Silhouette sign, air bronchogram, Kerley B lines, ground-glass opacity - with explanations of their mechanism and meaning.
Part 4 - Common IM Conditions with their Imaging Patterns:
- Pleural effusion (with the volume thresholds - 200 mL, 500 mL, 1000 mL rules)
- Lobar collapse (by lobe, with the "bronchogenic carcinoma until proven otherwise" rule)
- Pneumonia patterns (lobar vs. bronchopneumonia vs. atypical)
- Pulmonary edema stages (cephalization → Kerley B → bat-wing)
- Pneumothorax (including the supine deep sulcus sign)
- Mediastinal widening with the 4 T's
Part 5 - Abdominal & Other Imaging: AXR emergencies, US, CT abdomen.
Part 6 - Radiation Doses: A table you'll likely be tested on.
Parts 7 & 8 - Quick-Reference Sign Table + High-Yield Exam Summary: Perfect for last-minute review before class.
