Disclosed herein are novel approaches to thyroid cancer therapy. These approaches include methods to enhance thyroid specific gene expression, for example methods to enhance expression of thyroglobulin and / or the Na<+> / I<-> symporter in thyroid cancer cells. Enhanced expression of thyroid-specific genes promotes cellular differentiation and reduces biologically aggressive behavior such as invasion and metastasis. In addition, enhanced expression of thyroglobulin and / or the Na<+> / I<31 > symporter increases the ability of thyroid cancer cells to concentrate iodine or iodide, thereby making the cells more susceptible to radioactive iodine therapy. Also disclosed herein are methods for detecting thyroid neoplasms in a subject, by administering a therapeutically effective amount of a histone deacetylase inhibitor, administering a detectable agent whose uptake or concentration in thyroid cells is increased by administration of the histone deacetylase inhibitor, and detecting the detectable agent.

When the brightness of a subject detected by a detecting device 4 is higher than a predetermined value, for example 700 [cd / m2], a switching judgment circuit 5 judges that an area sensor (solid-state image-sensing device) 3 should perform logarithmic conversion.

When the brightness of the subject detected by the detecting device 4 is lower than the predetermined value, for example 700 [cd / m2], a switching judgment circuit 5 judges that the area sensor 3 should perform linear conversion. In response to this judgment by the switching judgment circuit 5, the switching signal generating circuit 6 outputs a switching signal to instruct the area sensor 3 to perform linear conversion.
