Patients (88) with maxillary-facial abnormalities were studied with 99mTc-labeled phosphate compounds. Straight and tilted anterior views plus oblique orbital and lateral views were correlated with 201Tl transmission images of a dried skull. Interpretation of any single view may be hampered by various superimposed structures. Careful patient positioning with multiple views allows for parallactic correlation which is crucial if radiotherapy, biopsy or corroborative studies are planned.
