A, For sagittal plane images, forearm is held pronated and hand lies flat on table. Forearm crosses gantry at angle of approximately 45 degrees (roughly in line with abducted thumb metacarpal). B, Scout images are obtained to confirm appropriate orientation and to ensure that entire scaphoid is imaged. Sections are obtained at 1-mm intervals. C, Images obtained in sagittal plane are best for measuring intrascaphoid angle. D, For coronal plane images, forearm is in neutral rotation. E, Scout images show alignment of wrist through gantry of scanner. F, Interpretation of images obtained in coronal plane is straightforward. (Copyright 1999 by Jesse B. Jupiter, MD.)
