Microradiography of Microcalcifications in Breast Specimen: A New Histological Correlation Procedure and the Effect of Improved Resolution on Diagnostic Validity Table 1 BIRADS classification in conventional radiography and microradiography. Changes by microradiography were only rated if diagnosis changed from the benign group (BIRADS 2 and 3) in to the malignant group (BIRADS 4 and 5) and backwards, respectively. No change correct is “No (c)” and no change false is “No (f)”.
