Touch imprint cytology (TIC), is a real-time method for microscopic examination of core needle biopsy specimens. TIC provides cytologic confirmation of needle position within the target lesion, which may improve diagnostic yield. An experienced cytopathologist or cytotechnologist is required for assessment of TIC. Inexperience can lead to longer procedure time and unnecessary manipulation of the biopsy needle, which may result in higher procedural complication rate. Unfortunately, many radiologists may not have access to experienced cytopathologists/cytotechnologists. For these reasons, it can be extremely useful for the radiologist to determine cytologic adequacy of the biopsy material themselves. Teaching goals: 1. The radiologist will have an understanding of the procedure for creating meaningful TIC slides 2. The radiologist will be able to determine adequacy of material on a broad array of histologies

Introduction Definition of touch imprint cytology (TIC) Review material required for TIC Learn technique for proper TIC preparation Identify properly and improperly stained slides Review of cytologic findings, anatomically divided (lung, pleura, mediastinum, chest wall). - Normal cells - Inflammatory findings - Infectious findings - Benign findings - Malignant findings Sample cases Summary
